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 level gauges have a special design, which includes:
