Liquid Level Indicators
Series 40000 / 41000
Protectoseal Series 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.
