Differential pressure is a measurement between two different pressure sources. For example it could be the pressure difference across a filter, valve or restrictor. GNW offer a range of differential pressure gauges for a wide variety of applications and industries. Our sealed sensor systems accurately measure liquid level, flow and other differential pressure
 
Manufactured as either diaphragm (cell), capsule or Bourdon tube type gauges, we are able to offer many different configurations of gauges. Please contact us with your requirements.
