Connecticut Patent of the Month – October 20

Gem Sensors, Inc. is a global supplier of sensing and control solutions. Their portfolio spans from liquid levels to flow and pressure sensors. Liquid level indicators need to be durable for use in a range of environments – including cold and low power operations. Unfortunately most of those on the market are difficult to use in dark, tight, confined, or hard to reach locations. Gems Sensors’ design tackles these limitations – and for that reason, they have been granted a patent.

Their patented design offers a safe alternative to sight glasses which are prone to breaking or becoming cloudy. The device consists of a tank and second housing in fluid communication. When the two liquid levels are approximately equal, a float in the second housing cooperates with the circuitry, opening LED light switches which transmit light through a light-transmissive cover.

This high visibility indicator makes liquid levels easy to read in any conditions. In addition, the water level indicator is isolated from the measure media; therefore, SureSite® water level gauges can be used where sight glasses are not even a consideration.
