Differential Pressure Gauges - Dwyer

Differential pressure gauges measure the difference between two pressure points. They show filter loading, flow through orifices, level in pressurized tanks and pressure drop across equipment.

DP Gauge Options

  • Diaphragm DP gauges – low differential ranges
  • Piston DP gauges – high line pressures
  • DP gauges with switches – alarms and control
  • Backflow test kits – backflow preventer testing
  • Accessories – manifolds and mounting kits

Choosing a DP Gauge

Specify differential range, maximum line pressure, wetted materials and connection. Use 3-valve manifolds to protect gauges during startup.

Centro supplies differential pressure gauges and accessories.
