Rubin-1M

The level recorder performs the following functions:
- Registers and records “liquid/gas” states on one or two controlled levels (controlled levels are determined by the placement of the sensors on the outer surface of the tank)
- Automatic or manual management of the actuator (latch or valve)
- Automatic calculation of the number of discharge / filling cycles
- Display on the graphic display of the recorder the level of liquid with respect to the controlled levels, the state of the actuator and the number of cycles
- Reception and transmission of telemetric data to an external telemetry system
- - Internal diagnostics of the performance of the recorder and its tuning
- Archiving of operational parameters
