The Petrotape Gauging System is a cost effective solution for monitoring above or below ground storage tanks that are at or near atmospheric pressure. Gauged products include gasoline, fuel oils, crude oils, kerosene and diesel fuel with temperatures up to 225°F (107°C). Petrotape is a packaged system consisting of the unique resistance-tape sensor, a compact filter assembly, a sensor housing and a two-wire 4-20mAcurrent transmitter. It is available in overall lengths of 3 to 100 feet (1 to 30 meters). The filter assembly protects the sensor from moisture and contaminants and provides pressure equalization. The stainless steel sensor housing mounts to a 3 inch flange. Excitation required is nominal 24VDC and the system is intrinsically safe with the use of FM approved zener barriers. Petrotape offers the option of adding one temperature detector and corresponding 4-20mA output for monitoring temperature.
