Differential Pressure Gauge
120 Series (Piston Type)
Midwest 120 Series Differential Pressure Gauge is a piston type pressure gauge that measures differential pressure through the movement of a floating piston magnet against a calibrated spring. The gauge pointer, outside the pressure housing, follows the movement of the piston magnet and indicates differential pressure.
- Midwest 120 Series Piston Type Differential Pressure Gauge has a simple, rugged, compact design.
- More cost effective and more accurate than using two pressure gauges in monitoring differential pressure.
- Weather-resistant construction standard.
- Shatter resistant lens.
- Midwest 120 Series Differential Pressure Gauge can use in measuring the pressure drop across filters, strainers, separators, valves, pumps, chillers, etc., and for local flow indication and control.
