KROHNELevel MeasuringInstruments

KROHNE level production and marketingfacilities are located in Germany, France,England, the United States and other count-ries for a variety of reasons. Primarily to gainan international edge in applications.

We make our products globally applicable.

The latest in quality assurance and a parti-cularly intense KANBAN production help usto drastically improve delivery speed downto a few days for regular products and only afew weeks for specials.

The KROHNE Strategy

KROHNE is present in almost every plantand process in the world. A global player, wereact quickly to your customer’s demands,whatever they ask, whenever they ask.

We are members of all important industrialassociations to ensure we anticipate theindustrial trends of the future, and then setthe benchmarks that others follow.

At KROHNE, we pride ourselves on beingeasy to do business with. Our key objectivesare to offer the best products for your applications, and to ensure that co-operationwith us is as easy as possible, we supportall our sales activities with extensive pre-and post-sales consultancy and technicalassistance.

KROHNE – easy to work with.

We offer a comprehensive and versatile range of level gauges and levelswitches for level measurement.

KROHNE level products are found in all industries, in all types of storagetanks and silos, in hazardous areas, onshore and offshore as well as ontanker ships, road and rail transporters.

Implementation of various measuring principles, advanced technologyand stringent quality control procedures have produced measuringinstruments which guarantee high accuracy even under extreme operating conditions. Applications extend from liquid sulphur at 284°F(140°C) to the storage of liquefied gases; from tanks on oceangoingships to storage tanks in nuclear power stations.

Our experience in the industry enables us to adapt to a wide variety ofapplications in every industry. You can count on KROHNE for accurate,reliable measurements, even under the most difficult conditions, all atan affordable price.

KROHNE level measuring instruments meet the requirements of EMCguidelines and CE directives. All factories are certified to ISO 9001.

Official approvals are available for many of our devices as follows:

� FM and ’Ex’ certificates of conformity

� Approval as part of an overfill protection system

� Approvals in conformity with the German pressure vessel code andvarious other international approvals

Our devices can be fitted with a choice of user-specific processconnections. Various interfaces such as RS 485, Modbus, PROFIBUS-PA, Foundation Fieldbus and HART® are available for intelligent datacommunication.
