Overview

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 Model 140-LLI is designed to have a long service with minimal maintenance requirements. Precision machining and calibration provide superior performance and accuracy of measurement. The Model 140-LLI utilizes 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 atmosphere.

Operation

Head pressure moves the diaphragm (attached to a shaft) resulting in a linear motion. The shaft connects to the indicator at a pivot point. At this pivot point the linear motion transfers into rotary action, which then moves the indicator to accurately show the liquid level.
