Differential Pressure

Test Gauges

Mid-West Instruments has engineered a series of differential pressure transmitters with the ability to transmit data signals. The microprocessor based instruments are equipped with proprietary magnetic sensors that convert the differential pressure gauges' normal magnetic movements into electric signals.

Backflow Test Gauges

American Backflow has a large inventory of certified backflow test gauge equipment, hoses, and test fittings. We have a wide selection of analog test gauges, and also provide backflow test gauge calibration services.
