Series DP3 Differential Pressure Module
Wireless, Measures Differential Pressure, Air Velocity, and Flow
The Series DP3 Wireless Differential Pressure Module is a compact, highly
accurate, auto-ranging differential pressure module ideal for low flow applications.
The Series DP3 is used in conjunction with the Dwyer Mobile Meter® application
software to view pressure drop across filters, static pressure in ducts, and velocity
pressures from pitot tubes or air flow stations.
