L628T type flow meter

  • Application occasions

    Gas liquid two-phase metering of conventional natural gas wet gas, Shale gas, coal-bed gas and wet saturated steam, and flow metering of sewage containing bubbles, liquid containing impurities, general gas containing impurities and mud can also be applied

  • Structural composition

    It consists of an averaging tube, a composite pressure sensor, a temperature sensor, and a flow computer.

  • Working principle

    When using standard orifice elements to measure liquid containing gases, due to necking and the collision and separation effect between the fluid and the orifice, liquid accumulation occurs upstream of the throttling element, resulting in the phenomenon o
