Differential Pressure Gauge (MMWC)

A Differential Pressure Gauge (mmWC type) is an essential instrumentation device used for precise monitoring of pressure differences across filters, strainers, orifices, heat exchangers, and pipelines in boilers, heaters, and process piping systems . It measures the pressure drop between two points, typically expressed in millimeters of water column (mmWC) , ensuring safe, efficient, and reliable operation of process equipment.

In boiler and heater systems, the gauge provides critical insights into flow resistance, filter choking, or fouling of heat exchangers, enabling preventive maintenance and avoiding unplanned downtime. With its robust design, corrosion-resistant materials, and accurate sensing mechanism , the differential pressure gauge delivers dependable readings even under demanding industrial conditions.

This instrument is widely adopted in steam boilers, hot water generators, thermic fluid heaters, and chemical/petrochemical process pipelines , ensuring operational safety, energy efficiency, and extended equipment life.

Applications : Monitoring filter clogging in boiler feedwater and process lines. Measuring pressure drop across heat exchangers, strainers, and scrubbers . Ensuring correct flow measurement with orifice plates and venturi tubes. Used in combustion air & flue gas monitoring in boilers and heaters.
