The differential pressure gauge is one of the most overlooked and forgotten measurement instruments in the industry. This is surprising because these devices have a tremendous variety of applications. They have the ability to monitor filter systems, display liquid levels, and even measure flow rates based on a difference in pressure. Measuring flow rates with these gauges is particularly interesting because they link the difference in pressure of a piping system to a square root relation of ...This story is related to the following:Sensors, Monitors and Transducers Sponsored by: BEI Sensors (BEI Industrial Encoders) - Cat Sponsor Jan 2014 Search for suppliers of:
