Liquid Level Indicators
Protectoseal Series Nos. 40000 / 41000 Liquid Level Indicators are used for accurate liquid level gauging of fixed roof tanks storing oil, water, solvents and other products. The units are designed for simple, easy installation for “tanks-in-service” or “tanks-out-of-service” and to provide a maximum of trouble-free service. They are especially recommended for applications that require a low cost, low maintenance method of liquid level gauging. Series 40000 / 41000 Indicators are float-actuated, and have a steel target that runs up and down a calibrated board to register the tank liquid contents level. The board is mounted outside of the tank and has bold, legible markings to permit quick, convenient readings.

Automatic Tank Gauge
Protectoseal Series No. 42000B Automatic Tank Gauge provides high gauging accuracy in measuring liquid level in all type of low pressure cone roof, floating roof and underground tanks. They help prevent vapor loss and reduce the time needed for taking readings. The float-operated gauges are compact and have large, legible numerals which permit quick, accurate readings of the displayed liquid level. The gauges may be used on tanks up to 65′ high and for pressure ranges up to 50 PSIG. Easy to install, they can be conveniently mounted at the top of the tank or mounted at the side of the tank for ground reading. Float movement activates a negator spring motor that rotates the liquid level indicating wheels to their appropriate positions in the viewing window.
