Home Products and Solutions Metering Device

CTN-2020 series separation and metering device (heavy oil well metering)

  • Application occasions

    Suitable for conventional oil wells, SAGD oil wells, condensate natural gas wells, heavy oil wells, etc. in oil and gas field surface processes.

  • Structural composition

    By sampling electric on-off valve, discharge electric on-off valve, separation storage pipe, double flange differential pressure transmitter, mass flow meter or density meter or moisture content meter, electric heater, temperature sensor, explosion-proof

  • Working principle

    The metering device consists of a gas-liquid separation metering part and a bypass sampling moisture content measurement part (the two parts do not interfere with each other and work independently). Electric three-way valve sampling, double flange Level s
