Differential Pressure Applications

Liquid Level
Pressure differential between bottom and top of tank allows for level readings on pressurized tanks. Popular in cryogenics and other liquid systems. Gauge scales can read in percentage filled or height of fluid. Specify specific gravity of fluid and height of tank when ordering.

Filters/Strainers
Pressure drop across filter or strainer informs operator when it's time to replace, backwash or bypass filter elements. Monitoring prevents servicing too late or too early. Clean and dirty scales are popular. Our differential pressure gauge switches can be used to automatically initiate cleaning at a specific setpoint.

Heat Exchangers
Pressure drop across heat exchangers indicates problem conditions such as scale or debris buildup. Monitoring improves efficiency by alerting operator of problem conditions so that proper temperature and flow rate can be maintained.

Flow Rate Indication
Flow scale based on differential pressure is popular on venturi, orifice plates and other primary flow elements. This approach is an inexpensive and accurate alternative for large and small pipes. Specify the differential pressure that the flow rate is based on when ordering.

Backflow Prevention
Used in backflow prevention test kits, our gauges are popular for testing backflow prevention valve operation. Pressure drop is an indication of valve performance. Regular monitoring of these valves ensures the safety of public water supply.
