2022TANK indicator is designed for liquid tank applications.
It is connected to a tank level transmitter with a mA or V
signal. The indicator can feed a level transmitter with a 24 V
150 mA supply.
This mA or V signal is linearized to a level reading using up to
ten free linearization points. They are mA - level pairs. Any of
the points can be edited afterwards. The level can be expressed
in any unit, e.g. mm or m or inches.
Liquid volume is then acquired from the level reading using up
to 32 free linearization points. These are simply level - volume
pairs. Again, the volume can be expressed in any unit. The
six-digit display allows displaying readings up to 999 999.

The indicator can be configured using the front panel or
alternatively using a serial connection and a free software
Mekuwin. The serial connection allows to read the level and
volume using Nokeval SCL protocol, whose specifications are
available to everyone. The serial connection is on an option
card.
The meter can be equipped with two or three alarm relays using
an option card.
This meter is a part of the 2000 series. It is available as a
96x48 mm panel meter with 14 mm digits (2022TANK) or in a
wall-mounted IP65 enclosure with 20 mm digits (28002022TANK).
