The BSRIA Instrument Solutions DPWA series of digital pressure indicators has been designed to give the user all the features required for measuring differential pressures up to a maximum of 10 bar (model specific) in water systems.

The DPWA is a handheld pressure indicator with a remote transducer manifold assembly and is designed for the easy measurement of differential pressures in non corrosive systems. Typical applications include :-

• Differential pressure measurements across balancing valves
• Differential pressure measurements across orifice / venturi metering stations
• Hydraulic differential pressure across pump heads.

Overview

Features

In order to aid the operation of the DPWA an “equalising valve” has been fitted to the manifold assembly to allow the quick & accurate zeroing of the instrument while still connected to pressure.

The DPWA has 16 pressure units of measurements, including:

  • mbar, bar, psi, mH2O, inH2O (4 & 20°C), ftH2O (4 & 20°C), inHg, mmHg, mHg, Pa, hPa, kPa & kgf/cm².

An optional user defined pressure unit may be defined at manufacture.
