Reflectometric level gauges KRU-1R (-1RV)

The principle of operation of the level gauge is based on the method of pulse reflectometry, which consists in transmitting a short electric pulse along a long line, which is reflected when it reaches inhomogeneity (the interface of media).

The composition of the level meters includes primary and secondary converters. The primary converter can have a monoblock design.

The primary converter contains an installation flange, on which a sensitive element is fixed with the help of a special insulator, which is a waveguide, the length of which determines the level measurement range.

The secondary converter provides power to the primary converter, an indication of the output signal and interfacing with upper-level systems via the RS485 interface.

The KRU-1R reflectometric level gauges are designed for continuous measurement of the level of liquid media.

Depending on the operating conditions, the level gauges have versions that differ:

• the measurement range;
• the value of the working pressure of the measured medium;
• the design of the primary converter (coaxial, cable, two-rod).
