DIR110NN

TANK SIDE INDICATOR■ 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, temperatureand other operation status. Required data for tank related are
displayed on it at the tank side, resulting in easier tank control andmanagement 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.
