A vessel, containing liquid that has a variation in level that is to be
monitored, with a high-level alarm set on Relay 1 and low-level alarm set on
Relay 2.
In this example, when the level rises to 2.38 m, relay 1 will come on until the
level drops to 2.24 m when it will turn off. If the level drops to 0.28 m, then
relay 2 will come on until it rises 0.42 m when it will turn off.
The display will show the level in the tank.
The mA output will be representative of level where 4mA = empty level (0%)
and 20mA = 2.8m (100%).
