■ GENERAL

DIR110NN is a tank side indicator for tank gauges.

Connected to Tokyo Keiso's tank top servo operated tank gauge

FW9000NN series, DIR110NN indicates liquid level, temperature

and other operation status. Required data for tank related are

displayed on it at the tank side, resulting in easier tank control and

management with time saving.

In addition to indicating functions, maximum 6 points relay output

are prepared. This function makes easier connection to higher

level computer and/or peripheral equipments.

By accessing magnet sensors, shown as arrows on the indicator,

various data are pre-settable for operating FW9000NN.
