  • Differential flowmeter
    Patent number: 4016760
    Abstract: Gauge having a Bourdon tube sealed in a pressure chamber and the tube and chamber connected to a fluid line, respectively upstream and downstream of a restriction therein, for indicating through an indicator operatively connected to the free end of the tube variations in the flow rate in the line by the effect on the tube of pressure differentials across the restriction. An orifice and an equalizing valve in the upstream connection protect the tube against sudden overpressures and limit the maximum pressure differential thereon.
