Siemens SITRANS LR250 Two-Wire Pulse Radar for Liquid and Slurry Level Measurement

Siemens SITRANS LR250 two-wire continuous radar level transmitter for liquid and slurry applications is easy to install and quick to configure. Its narrow horn and beam, along with Siemens Process Intelligence algorithms, ensure that the LR250 provides high accuracy of low and high levels, even with low dielectric media.

The LR250 is now available in four versions: a horn antenna for liquid and slurry measurement, a PVDF antenna for use with corrosive or aggressive materials, a flanged encapsulated antenna for use with corrosive or agressive media, and a hygienic encapsulated antenna for sanitary applications.

The LR250 horn antenna model is a suitable replacement for the retired SITRANS LR400 liquid level radar transmitter.
