Item # item-1068, Taylor Valve

An industry leader in the design and manufacturing of fluid control and measurement devices, Taylor Valve Technology control products are engineered and manufactured to the highest standards of precision to deliver a greater level of measurement accuracy with a minimum of moving parts.
For a more environmentally responsible design and more accurate results, you can always count on Taylor technology.

Taylor Model 140-LCD

A head pressure type level indicator, the Model 140-LCD continuously indicates liquid level in an atmospheric (vented) vessel- The Model 140 is a significant upgrade over other products on the market, helping to ensure longer service life and reduced maintenance requirements while increasing the accuracy of measurement.
The Model 140 utilizes a precision crafted diaphragm as the sensing element. Its superior design isolates the mechanical working parts in the unit from liquid inside the vessel.

High-performance, Taylor-made features:
  • Easy To Adjust - The unit features external Zero Adjust and Span Adjust knobs that can be field adjusted in less than 15 minutes without changing the vessel's liquid level or disassembly of the gauge.
  • Easy To Read - Scale reads the same as a hand tank gauge; no need to convert PSI of head pressure into feet and inches of water to get the correct reading.
  • Corrosion Resistant - 100% of all internal and external parts are constructed of corrosion-resistant materials.
  • No Spills - Unit equipped with two diaphragms. If the primary diaphragm fails, the sight glass indicator will tell the operator of the failure, while the secondary diaphragm will continue to display the correct gauge reading.

Pulsation Dampener minimizes pressure spikes caused by irratic flow of liquid into or out of the vessel, delivering a constant pressure on the spring for more accurate gauge readings.

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.
