Description:

 The Chemtape 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 general industrial chemicals,pharmaceuticals,and petro-chemicals with temperatures up to 225°F (107°C). Chemtape 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 contaminates 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. Chemtape offers the option of adding one temperature detector and corresponding 4-20mA output for monitoring temperature.

Features:

 • Complete, intrinsically safe level gauging package for chemicals

• Hastelloy™ construction provides excellent chemical compatibility

• Tank top mounted for easy installation, stillpipe not required in non-agitated tanks

• Sensor has no moving parts to stick or break; virtually maintenance free

• Optional combined level and temperature capability; wide operating temperature

• Works with Wireless, WRT & WBR System
