Series 41000 Liquid Level Indicator

Protectoseal Series No. 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. 

The Indicators are especially recommended for applications requiring a low cost, low maintenance method for liquid level gauging and where operations necessitate accuracy to ± 1 inch. 

The Indicators are float-operated with a steel target that runs vertically up and down, registering tank contents on a calibrated board that is mounted outside of the tank for quick, convenient readings.
