Liquid Level Controller
The Model 140-LLI is the oil and gas industry's leading liquid level controller on the market. It utilizes cutting-edge diaphragm sensors to give you a constant analog readout of the liquid level in a vented container.
The Taylor Valve Technology Model 140 Liquid Level Controller requires minimal maintenance due to its modular design.
Its precision diaphragms have been precision calibrated to ensure consistent, accurate readouts.
The seal design ensures that the mechanical parts are isolated from fluids and corrosive agents in the atmosphere.
Description
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 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.

Pulsation Dampener:
The pulsation dampener minimizes pressure spikes caused by erratic flow of liquid into or out of the vessel, delivering a constant pressure on the spring for more accurate readings.
Features
All conections are stainless steel as a standard.
Span and zero adjustment knobs are on the exterior of the unit.
A secondary diaphragm ensures that a leak in the primary diaphragm will not result in a leak to the unit interior.
A leak indicator between the primary and secondary diaphragms lets the operator know if the primary seal is compromised.
