Liquid Level Transmitter is constructed by using all sealing isolated diaphragm & oil-filled level sensor and special electrical circuit.

This ULB3 model is featured with high measuring accuracy, good stability, long life, and easy installation etc.

It uses unique craft sealing structure, has good performance against leakage, and reliable operation of submerging liquid for a long time.

According to three mathematical model relations of the measured liquid's intensity, density, and level, through the level transducer to measure the fluid's pressure which is proportional to fluid's depth, and transforms its signal to standard 4~20 mA electric current signal (or standard voltage signal) through its amplifying circuit. 

ULB3 liquid level transmitter is easy to be installed.
