The Model 120 Tank Level Indicator accepts a 4-20mA signal from a wide range of level sensors, including pressure transmitters, ultrasonic sensors or capacitance probes, and displays both level and tank contents on a large LCD display.
Solid state relay outputs provide up to four level alarms and a 25 point non-linearity correction table allows the instrument to be programmed to fit most tanks.
The Tank Level Indicator is powered entirely from the 4-20mA current loop and, therefore, requires no external power or batteries.
The instrument is fully programmable with setup parameters such as span, offset, alarm levels, etc, stored in a non-volatile memory which will retain all data for more than 10 years without power.
The Model 120 is housed in an attractive IP67 (Nema 4X) polycarbonate enclosure which is completely watertight.
A wall mounting bracket is supplied as standard, while a 2″ pipe mounting bracket is available as an option.
