Differential pressure gauge / gas flow FCO560

The FURNESS CONTROLS FCO560 gas flow and differential pressure calibrator FCO560 meets the requirements for low differential pressure calibration of transmitters, transducers and pressure switches.

An external pressure transmitter can be used as a reference for calibration of higher pressure equipment.

The unit can be combined with a laminar element to provide a flow calibrator that can cover flow rates from 1 ml/min to more than 30,000 l/min.
