Ultrasonic Flowmeter SL1288i

About SL1288i

Applications


SL1288i Portable Ultrasonic Flowmeter enables theuser to do flow measurement checks at many points in a flowprocess without the need for a permanent installation.

This ultrasonic flowmeter adopts Gentos unique PICOFLY time measurement technology, which could make the resolution reach to 10 picoseconds(0.01 nanosecond). It realizes the high respondence and high accuracy ultrasonic measurement technology and application.

Comparing with other traditional flowmeter or ultrasonic flowmeter, it has distinctive features such as high precision, high reliability, high capability and low cost, the flowmeter features other advantages:

PICOFLY technology designed. Less hardware components, low voltage broadband pulse transmission, low consumption power.Clear, user-friendly menu selections make flowmeter simple and convenient to use.Daily, monthly and yearly totalized flow.Parallel operation of positive, negative and net flow totalizes with scale factor (span) and 7 digit display.

Installation Site Selection

When selecting a measurement site, it is important to select an area where the fluid flow profile is fully developed to guarantee a highly accurate measurement. Use the following guidelines to select a proper installation site:

1.Choose a section of pipethat is always full ofliquid, such as a verticalpipe with flow in theupward direction or a fullhorizontal pipe.

2.Ensure enough straightpipe length at least equalto the figure shown belowfor the upstream anddownstream transducersinstallation.

3.Ensure that the pipesurface temperature at themeasuring point is withinthe transducertemperature limits.

4.Consider the insidecondition of the pipecarefully. If possible,select a section of pipewhere the inside is free ofexcessive corrosion orscaling.
