Pressure liquid level gauge with Modbus bus

This sensor indicates the height of the liquid column by measuring the difference in pressure at the bottom of the tank, where it is immersed, and the atmospheric pressure. The ready result is sent via the Modbus bus.

The sensor is calibrated for water column measurements.

Custom Modbus module configuration for LK 4 and LK 3 is available here
