Differential Pressure Filter Monitors

Measure pressure drop across filters or strainers to inform the operator when it's time to service the filter. Monitoring prevents servicing too early or too late.

Save Time & Money

Reliance on scheduled maintenance or using two pressure gauges often results in loss of filter efficiency and wasted time. One simple differential pressure gauge eliminates this wasted time and inefficiency and also errors - which means it pays for itself. One differential pressure gauge with a red arc, or a clean/dirty scale, or electronics can immediately indicate an alarm condition, saving time and problems.

Orange Research has supplied differential pressure filter gauges for over 50 years. Our piston DP models are the low cost gauges for liquids. Diaphragm DP models are used on gas filters. Use on filters or strainers in the most demanding environments. Orange offers the most standard features and options in the industry.

Filter Gauges

Orange is the #1 supplier of filter gauges. Select from 1-inch mini indicators to 6-inch gauges. Add a red arc or electronics to indicate when it's time to service the filter. Pressure bodies are machined from solid blocks of aluminum, brass or stainless steel, allowing for up to 10,000psi working pressures on some models.

Switches & Transmitters

Switches are available in SPST, SPDT or DPDT. Select one or two switches per unit. Transmitters are available with either 0-5Volt or 4-20mA outputs. Electronics are available with or without a gauge for both local and remote monitoring. Electronics are available for normal or hazardous locations.
