FLOW MONITORING AND CONTROL SYSTEM

摘要

The invention provides a flow measurement and control system (30) that is suitable for many industrial applications. The system has solenoid operated selecting valves (52, 53) that can be connected to pressure tappings of apparatus in which fluid flows. Each selecting valve is mounted to a manifold (34, 37) so as to be in fluid communication with the inlet of a pressure transducer (54). A control means (50) is provided to operate the said valves so as to successively connect one or more of them to the transducer while isolating the others therefrom. Valves (40, 41) are preferably provided to enable connection (also under control of the control means) of a purge supply for the valves and pressure lines connected to them.
