The Model 575 intrinsically safe level transmitter (photo, p. 24) and the Model DDMC meter/controller can continuously monitor the fuel level in diesel storage tanks. The Model 575 level transmitter is placed in the liquid, and an optional conduit adapter is used in the tank to protect the cable. The Model DDMC meter is used to power the Model 575 transmitter through approved electrical barriers. The DDMC also provides a continuous display of the level in the tank. The Model 575 submersible level transmitter is a hydrostatic level product for quick, reliable level measurement. It comes standard with CSA Intrinsically Safe approvals for many different level-monitoring needs, including lifts stations, inventory tank measurement, landfills, reservoirs or any type of water-treatment facility. — Ametek U.S. Gauge, Horsham, Pa.
