HHTPF-LV is an in-line gas-liquid two-phase flowmeter, which suitable for natural gas well measurement of liquid and gas. HHTPF-LV uses a Long-Throat Venturi as throttling device, which can provide two differential pressures in the upstream and downstream. By using these two differential pressures, each flowrate can be calculated through self-developed algorithm of double differential pressure.
HHTPF-LV combines the basic theory of gas-liquid two-phase flow, computer numerical simulation technology and real flow test, can provide precise monitoring data in the whole life of a natural gas well. More than 350 flowmeters have been successfully installed and operated at the wellhead of gas field in China, especially it has been widely used in the field of shale gas in recent years.
