1.0 Introduction

This Instruction manual describes the S&DL mini software version 1,installation, use and maintenance of the S&DL mini in general. The S&DLmini software is used to view existing logger settings, program new settings,launch logging sessions, monitor current readings, download and view dataand export data.

The S&DL mini is designed to measure groundwater and surface water levelsand temperature. The S&DL mini measures both temperature andtemperature compensated water levels. Table 1.1 outlines the generalspecifications for the S&DL mini. Table 1.2 details important technicalspecifications. The S&DL mini is programmed using either a desktop orlaptop computer, which connects to the S&DL mini via an optical readercable. The optical reader cable uses an infrared data reader connected to theS&DL mini and a USB or RS232 Serial port to communicate information toand from the S&DL mini and computer.


1.1 Level

The S&DL mini uses a state of the art Stainless Steel Piezoresistive Siliconpressure transducer. The stainless steel transducer provides water level readingsthat are reliable and consistent. The S&DL mini measures total (absolute)pressure. When the S&DL mini is operating in open air, it is recording barometricpressure and converting that pressure reading to its water level equivalent abovethe mini’s pressure zero point of 9.500m. When submerged, it is recording thecombination of barometric pressure and water head pressure. The S&DL miniconverts the total pressure reading to its corresponding water level equivalent.Actual water level is obtained by compensating for barometric pressure.

1.2 Barometer

The Barometer is and should be treated exactly as an S&DL mini. TheBarometer’s only differentiating feature is that it has a small level monitoringrange of 1.5m for monitoring barometric fluctuation.

Using an S&DL Barometer is the most accurate and convenient method of obtaining atmospheric pressure. When properly programmed, the S&DL Barometer can avoid barometric data time lags and any errorsintroduced due to moisture buildup, kinking or damage to vented cable. TheBarometric Compensation Wizard in the S&DL mini software simplifies theadjustment of the level measurements for barometric pressure changes, byusing the synchronized data from all S&DL Minis on site and the siteBarometer.

Manual methods can be employed to determine the absolute water levelusing barometric records collected on-site or available from a local weatherstation (i.e. Airport). If manually compensating for barometric pressure,export to a spreadsheet program to manipulate data.

1.3 Temperature

The S&DL mini records temperature compensated water level. Groundwaterand surface water temperature measurements are particularly important insituations where temperatures may fluctuate significantly, and whentemperature is used in determining liquid level, viscosity and the calculationof certain temperature dependent contaminant reaction rates. Temperaturemeasurements will be recorded between -20 to +50˚C, but level recordingsare only compensated for temperature within the range 0-40°C.

• Instrument type and corresponding serial number (sn) cannotbe changed; they are preprogrammed into each S&DL mini.

• Project ID: Input your own S&DL mini identification system. TheProject ID is limited to 32 characters.

• Location: Input specific site / location information. The location islimited to 32 characters.

• Sample mode allows you to chose the sampling measurement type.Linear sampling only in a user specified interval.

• Linear refers to a set time interval between reading collection. InLinear mode, the S&DL mini and Barometer have a total memorycapacity of 30,000 readings of Level, Temperature and time stamp.

• Sampling Rate: Choose from 0.5sec - 59hrs linear time interval.

Figure 5-1 S&DL mini Settings Window

5.2 Setting up Channel Information

In the lower portion of the S&DL mini Settings window is the window forsetting channel parameters.

Channel 1, "Level", includes the following parameters:

• Identification describes the measurement parameter of the channeland has already been configured as Level. The Level channelmonitors water column equivalent pressure. The Identification fieldwill be the data column heading and graph line name when viewingthe data. The Identification is limited to 32 characters

• Units refers to the channel’s units of measurement. There are 2 unitsof measure available for the user to select: cm, m.

• Offset: Inputting any value in offset will add that value to eachreading, which becomes the recorded value.

• Range refers to the full scale water fluctuation range capability ofyour S&DL mini. The full scale reading of the S&DL mini unit is basedon its metric range. The range of the instrument cannot be changed.

Channel 2: "Temperature", includes the followingparameters:

• Identification and Units, Reference and Range have been pre-configured and cannot be changed.

Note: Readingscan be correctedor offset withrespect to a

specific referenceelevation or datum for amuch wider spectrum ofnumeric Offsets as part ofthe Data CompensationWizard.


• Altitude in meters above sea level, at which the logger is actuallydeployed, is input in the Altitude field. Water column equivalentpressure decreases with altitude at a rate of approximately 1:1000.You can compensate for this by entering an elevation between -300mbelow sea level and 5000m above sea level. The readings will thenbe automatically compensated for elevation.

• Density Adjustment is used to adjust the range of the S&DL minibased on the sample fluid density. The range for the densityadjustment is from 0.9 kg/L to 1.1 kg/L. The range of the S&DL miniafter the density adjustment is based on the following formula.

Uncheck the Density Adjustment field to disable the Density Adjustment function.

Actual Range ÷ Density = Corrected Range

E.g. For 5m monitoring brackish front in a salt water intrusion study

5.000m ÷ 1.02 = 4.902


5.3 Setting up the S&DL mini Time

At the middle right of the S&DL mini Settings window are the controls forsetting the S&DL mini clock (Time Synchronization). By default in TimeSynchronization, the Enable box is unchecked. If you want to synchronizethe clocks of all S&DL minis, synchronize them to the computer time. Checkthe Enable box and select the time and click the synchronize button to setthe time in the S&DL mini. If you start the S&DL mini without synchronizingthe clock and the time difference between the S&DL mini and the PC is morethan 3 seconds, the software will give you a message asking “Do you wantto synchronize the clock?” Click “Yes” to synchronize the clock.

5.4 Program S&DL mini Settings

At this point you have completed editing the settings for your logging

session, click the button to send all the settings to the S&DL mini and the S&DL mini will store all the new settings. Now that the logger has beenprogrammed with your new settings, you can move on to Starting the logger.

5.5 Starting and Stopping the S&DL mini

To begin logging, click the button and a dialog box will open.

Figure 5-2 Start S&DL mini Window

There are two ways to start logging. Choose “Now” to start the loggingimmediately. The Status field in the S&DL mini Status window will state:Started and will indicate the logger time and the Start time. Free memoryindicates the number of readings remaining at the time of communication.


Choose to start the logging at a later dateand/or time. This Start mode is referred to as Future Start in the Statusfield. After confirmation, the starting time is stored in the S&DL mini and itwill start collecting readings at the specified time. When the Future Starttime is reached, the Status will change to Started.

After the S&DL mini is started, it will begin collecting readings. The Starticon will change to a Stop icon.

The S&DL mini can be stopped at any time before it reaches the maximumreading capacity. Starting begins a new recording session and clearspreviously stored data readings.

It is critical to note that all S&DL Minis log data in Slate mode, which meansthey will record data until stopped or their memory is full. When the memoryfills, the logger will Stop recording. For this reason, it is important todetermine, based on your start time and sampling rate, the date and timeat which the memory will be full and the logger will stop recording.

You can stop logging from the S&DL mini Settings window, by clicking the

Stop icon .

Battery life remaining is indicated in percentage remaining in the Batteryfield at the top of the S&DL mini Status block.

5.6 Saving and Retrieving Default Settings

With the Store settings as defaults icon you can store the settings of aS&DL mini into an *.ols file as a series of defaults. The *.ols file will savethe Project ID, Location, Sample Rate, Altitude, Density, Channel ID, Unitand Offset.

With the Retrieve settings from defaults icon you can retrieve thedefault settings from an *.ols file. This is particularly useful if programmingseveral S&DL Minis with similar identical settings. Keep in mind that Site /S&DL mini identification information will be identical and should bedistinguished from logger to logger or monitoring point to point.

6.2 Data Compensation

Click the Data Compensation icon to open the Data CompensationWizard. The Data Compensation Wizard is shown in Figure 6-7.

In the first window of the wizard, the user identifies the currently openedfile type. There are two file types: Barometric files (data that is retrievedfrom a Barometer) and Submerged S&DL mini file (data that is retrieve fromthe S&DL mini). After the selection of the file type, click Next and the DataCompensation selection window will open.

There are 2 data compensation options available: Barometric Compensation,Manual Data Adjustment.


Figure 6-8 Data Compensation Window- Compensation Selection

• Manual Data Adjustment requires the user to select the ReferenceTime from the data file and enter the new reading in the ReferenceDatum to replace the original level reading of that selectedDate/Time. This field is used to adjust the data by an offset value byinputting the Reference Datum value for that time when the offset ismanually measured. Please note that the value input into ReferenceDatum field will become the actual finished data point at thatdate/time. Therefore, the program computes a correction factor toadjust the existing data value after compensation is performed. Thiscorrection factor is then applied to all the data from that file.

The compensated data will be saved in a new *.oyo file. The default filename will be the <S&DL mini file name> with the word <compensated>added to the file name prefix. Alternatively, the user can name thecompensated file. Do not change or delete the file extension.

• Barometric Compensation requires the Barometric file and thesubmerged S&DL mini file and simply involves subtraction of thebarometric reading from the S&DL mini reading. If there is aninconsistency of the time stamp between the Barometric file and theSubmerged S&DL mini file, a linear approximation on the barometricdata will be performed.

If a barometer other than the S&DL Barometer is used, barometriccompensation can be performed in an external spreadsheet program.

9 Installation and Maintenance of S&DL mini

9.1 Installation

Many options exist for installation of the S&DL mini, but essentiallythese installation methods can be classified into two broadcategories: suspended or fixed installations.

1. In suspended installations, the S&DL mini is hung viasuspension wire or Direct Read Cable from the well cap, orsome fixed tie-off location, at the well head.

2. In fixed installations the S&DL mini is fixed in place by acompression fitting, a clamping mechanism or simple metalstraps.

Prior to commencing the discussion of installation techniques severalgeneral points related to S&DL mini installation should be made.First, it is recommended that the S&DL mini be installed in a verticalorientation. However, inclined or horizontal installation is acceptable.The location of the level sensor in the S&DL mini is indicated by thedimensions in Figure 9-1.

Care should be taken to avoid dropping the S&DL mini against a hardsurface. The pressure transducer diaphragm in the S&DL mini is ultrathin stainless steel and may be damaged if the S&DL mini is droppedor impacted. Further, the pressure transducer can be damaged if thelogger is over-pressurized by submergence greater than its Levelrange. The S&DL mini is warranted to pressures up to 2x of its fullscale Level range.

Other important considerations when installing the S&DL mini inpressurized or intermittently pressurized locations such as pressurevessels, pressurized pipes, pulse flow conditions, drop structures ornear hydraulics works, is to keep in mind the potential effect of wateror steam hammer and hydraulic jump. Water hammer is caused byan abrupt alteration of flow direction resulting in pressure surges.Steam hammer occurs when steam enters a cold pipe partially filledwith water. The hammer effect has the potential to significantlyincrease hydraulic pressure possibly exposing the pressure sensor topressures beyond its maximum rating. Hydraulic jump is aphenomenon that occurs when water is “lifted” or “ramped” byvelocity or flow obstructions. Hydraulic jump causes turbulence andcreates non-representative head conditions in the water column.Care should be taken to avoid logger installation at points susceptibleto hydraulic jump.

Figure 9-2Locking, Tamper-proof Cap

Figure 9-3 Picture of Direct ReadAssembly Components

9.1.1 Suspended Installations

Suspension Wire installation

OYO supplies stainless steel suspension wire assemblies including SSstranded wire and hooks available in a variety of lengths from 15m to 150m. OYO also supplies specially designed, tamper-proof, vented, lockingwell caps suitable for 50 or 100mm wells from which the S&DL mini can besuspended (Figure 9-2).

This type of installation is applicable to both submerged and barometricrecord applications.

Direct Read Cable Assembly Installation

The Direct Read Cable system is available to fit 25, 50, or 100mm wells,composed of the ordered length of Direct Read Cable, the Direct ReadWellhead, and the PC Interface Cable. The Direct Read cable threads to theS&DL mini, while the socket at the opposite end of the Direct Read Cable fitsinto the specially designed Direct Read Wellhead. After removing theprotective cap the PC Interface cable connects to the Direct Read socket atsurface and to the USB or RS232 Serial port on the PC (Fig. 9-3). While useof the Direct Read Wellhead is recommended and convenient, it is optionalas long as a satisfactorily secure alternative tie-off point is found for theDirect Read Cable. Follow these steps to install a Direct Read CableAssembly to the S&DL mini:

1. Remove the top cap from the S&DL mini, align and connect theoptical socket (two glass ‘eyes’ using the alignment pin) of the DirectRead cable to the S&DL mini by threading the coupling onto theS&DL mini tightly, but do not over tighten.

2. The S&DL mini and optical socket will fit through the hole in theDirect Read wellhead. Use the eyelet at the bottom of the wellheadto securely tie-off the cable and logger. Do not suspend the loggerand cable from the surface socket.

3. Remove the protective cap from the non-optical socket at thewellhead end of the Direct Read cable, seat the socket in the DirectRead Wellhead and align and thread it to the round socket of the PCInterface cable.

4. Connect the 9 pin USB or RS232 Serial connector of the PC Interface cable to the USB or RS232 Serial port on your PC.

5. The wellheads have an access port for a water level meter probe.

9.1.2 S&DL Barometer Installation

The Barometer is an S&DL mini with a small range of 1.5m adequate tomonitor the fluctuations that occur in barometric pressure. The Barometer’sreadings are used to barometrically compensate S&DL mini readings.Typically, Barometer readings range from 30 – 100cm when the Barometeris programmed with its operating altitude. Failure to input the correctaltitude will result in incorrect readings and may cause the pressuretransducer to record out of range. It is strongly recommended that thealtitude input be accurate to ≤10m. When the Barometer is programmed atits operating altitude, its readings can be used to directly compensate forbarometric pressure, the readings of any S&DL mini programmed at the



S&DL mini’s operating altitude, provided they have the same time range. Asa rule or thumb, a Barometer can be used to compensate all the S&DL Minisin a 30km radius.

To monitor barometric pressure correctly, the Barometer should never besubmerged. In well installations, it is recommended that the Barometer besuspended in one of the monitored wells above the high water point (Figure 9-4). For best reading accuracy, the Barometer should be installed ina similar thermal environment to that of the S&DL mini. In groundwaterwells, the Barometer should be suspended beyond the frost line and deepenough to avoid large temperature fluctuations. In surface waterapplications, the Barometer is best deployed in a dry well – a well embeddedin the bottom of the water body, but sealed at the base from water entry andvented to the atmosphere. If a dry well cannot be installed, the Barometercan be installed on a float in the stilling well.

9.1.3 S&DL Placement

Always ensure that the S&DL mini is placed below the highest expectedwater level within the water level fluctuation range for that logger (as shownin Table 1.2). For best accuracy it is recommended that a field zero readingbe taken after the S&DL mini has been started. To do this, use an accuratemanual water level meter to record the water level depth from the datumpoint, and record the time in which it was measured. As described in section6.2, this data can be entered into the data compensation window of theS&DL mini software to adjust data input relative to the field zero reading, thus providing accurate data that is directly comparable to manual water level readings.

Alternatively, the S&DL mini can be placed accurately measuring thesuspension cable or Direct Read Cable length from the transducermeasurement line (Figure 9.1) to the datum point at the top of the well. Thismeasurement must be recorded for later adjustment using the offset featurein the S&DL software or another spreadsheet program.

9.2 S&DL mini Maintenance

S&DL mini maintenance consists of cleaning the outside coated stainlesssteel casing, the pressure access holes and the optical infrared eyes. Therequired frequency of cleaning is dependent on several aspects of themonitored water quality. In freshwater with good to excellent water quality,the S&DL mini cleaning requirements will be very minimal; amounting to aseasonal or even annual maintenance inspection during long termmonitoring programs.

In most cases cleaning the S&DL mini can be accomplished by washing with mild, non-residual, non-abrasive cleaners. To clean the opticalcommunications eyes located under the top cap, a soft lint-free materialshould be used. Do not insert any object through the pressure access holesat the sensor end of the S&DL mini.
