SITRANS LR250 is your first choice for liquid level measurement in storage and process vessels up to 20 meters (66 ft).

The SITRANS LG series comes in four different models: LG240, LG250, LG260 & LG270 Technology: Guided wave radar Range: 300 - 75 000 mm Process Temp: -196 - +450C Vessel Pressure: -1 - +400 bar

The Type 8138 is a non-contact radar level transmitter for continuous level measurement. It is particularly suitable for use in small vessels that contain beverage liquids under sanitary process conditions.

The Type 8188 is a level measurement device with cable, rod, both interchangeable probe or with coax probe, designed for continuous level measurement. The unit is suitable for liquids, for industrial use in all areas of process technology. With a measuring range up to 75 m, the 8188 is best suited for tall vessels. Even process conditions such as strong steam generation, density fluctuations or changes of the dielectric constant do not influence the accuracy of the measurement. Build-up or condensation on the probe or vessel wall do not influence the measuring result. A liquid interface measurement is also possible with the Type 8188, typically an oil/water interface.

The Type 8137 is a non-contact radar level transmitter for continuous level measurement. The unit is available in two versions: - with thread and horn antenna (ø 40 mm) particularly suitable for use in small tanks and process vessels for measurement of practically any product. Also with flange and horn antenna (ø 40 or 75 mm) particularly suitable for use in storage tanks and process vessels for measurement of products such as solvent, hydrocarbons and fuels under extremely difficult process conditions.

The Type 8189 is a level measurement device with interchangeable rod probe, designed for continuous level measurement. The unit is suitable for liquids, for industrial use in all areas of process technology. the main application targets are in Food and Beverage (F&B) and pharmaceutical tanks to the new rod in stainless steel 1.4435 with Ra < 0.76 µm. For applications with corrosive liquids a PFA coated version is available.
