Differential pressure gauges
Description
Used for monitoring the differential pressure of fluids, both liquid and gaseous, even in the presence of high static pressure. It may indicate pressure drops or flow and level differences in filtration plants. Available with diaphragm seals for separating the process fluid, if the fluid is corrosive, highly viscous or it crystallizes.
Applications
Refineries, chemical and petrochemical plants, water and wastewater pressure control. Particularly indicated for filter monitoring.
