Abstract
A compact differential-pressure flow meter with reduced wiring is provided. The differential-pressure flow meter has first and second pressure sensorsA andB fixed to a base memberon upstream and downstream sides of an orifice memberalong a flow channel to determine a flow rate based on a pressure difference measured between the two sides of the orifice memberby the pressure sensors. The differential-pressure flow meter includes specific control boards disposed near pressure-sensing parts installed in the respective pressure-sensing device and a main control board disposed in a board installation space formed inside the base member. The specific control boards are connected to the main control board with wires passing through a plurality of wiring conduits provided in housings of the pressure-sensing device, and external wiring are connected to one of the specific control boards or to the main control board.
