The Model 220 Level and Contents Display 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 Level Monitor 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 retains all data for more than 10 years without power.
The Model 220 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. Alternatively, the Model 220 can be supplied as a panel mount instrument.
