The Model 140-LLI displays the level in a tank by sensing the head pressure on the diaphragm and converting it to movement of a pointer on a fixed scale, continuously indicating liquid level in an atomospheric (vented) vessel.
The Indicator is designed to have a long service with minimal maintenance requirements. Precision machining and calibration provide superior performance and accuracy of measurement while utilizing a set of precision crafted diaphragms as the sensing element, and the superior seal design isolates mechanical working parts from process fluids and corrosive agents in the
