Abstract
The utility model discloses a gas-liquid two-phase flow pitotbar flow meter. The gas-liquid two-phase flow pitotbar flow meter comprises a horizontal short circular pipe and a pitotbar flow sensor. A circular hole is formed in the bottom wall of the horizontal short circuit pipe. The pitotbar flow sensor inserts into the short circular pipe through the circular hole. The pitotbar flow sensor is connected with a first differential pressure transmitter through a connecting body and a first three valve set. The gas-liquid two-phase flow pitotbar flow meter further comprises a liquid level testing device for measuring liquid level of liquid inside the horizontal short circular pipe. The liquid level testing device is provided with a liquid flow connecting pipe and an airflow connecting pipe. One ends of the liquid flow connecting pipe and the airflow connecting tube are connected with a second differential pressure transmitter through a second three valve set. Airflow holes are formed in the top wall of the horizontal short circular pipe, and liquid flow holes are formed in the bottom wall of the horizontal short circular pipe. The other end of the liquid flow connecting pipe is communicated with the liquid flow holes. The other end of the airflow connecting pipe is communicated with the airflow holes. The gas-liquid two-phase flow pitotbar flow meter can accurately measure the flow of the liquid in a gas-liquid two-phase mixing pipeline.

Technical field
The utility model relates to a kind of bi toba flow meter, especially relates to a kind of gas-liquid two-phase flow Pitotbar flow meter of fluid flow when having gas-liquid two-phase fluid simultaneously in can the Measurement accuracy pipeline.
Background technology
The bi toba flow meter is to adopt the pitot tube principle to extract total head and the static pressure signal at fluid-transporting tubing axis place, total head and static pressure signal are introduced differential pressure transmitter, in differential pressure transmitter, difference by total head and static pressure obtains dynamic pressure, dynamic pressure input integrating instrument, go out rate of flow of fluid in conjunction with the density of fluid by dynamic pressure calculation at flow integrator, then in conjunction with the internal diameter of fluid-transporting tubing, the temperature and pressure of fluid, calculate the fluid flow in fluid-transporting tubing and show.Bi toba flow meter of the prior art, comprise the short pipe of level and bi toba flow sensor, have circular hole on the diapire of the short pipe of described level, described bi toba flow sensor circular hole thus extend in short pipe, and bi toba flow sensor is connected with differential pressure transmitter by connector and three valve groups.The bi toba flow meter of said structure can be measured the flow that only has single fluid in pipeline, sometimes the two-phase fluid medium that mixes of conveying gas, liquid simultaneously in pipeline, due to biphase gas and liquid flow being arranged in transfer pipeline, gas flow will occupy certain pipeline section, and the method that multiply by the sectional area of pipeline with flow rate of liquid is measured in transfer pipeline has the fluid flow of biphase gas and liquid flow inaccurate.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of gas-liquid two-phase flow Pitotbar flow meter that can the Measurement accuracy fluid flow when pipeline is carried gas and liquid two-phase fluid medium simultaneously.
for solving the problems of the technologies described above, the utility model gas-liquid two-phase flow Pitotbar flow meter, comprise the short pipe of level and bi toba flow sensor, have circular hole on the diapire of the short pipe of described level, described bi toba flow sensor circular hole thus extend in short pipe, bi toba flow sensor is connected with the first differential pressure transmitter by connector and the one or three valve group, also comprise a level gauging device of measuring liquid level in the short pipe of described level, this level gauging device has the gentle conductance pressure pipe of liquid conductance pressure pipe, one end of the gentle conductance pressure pipe of liquid conductance pressure pipe is connected with the second differential pressure transmitter by the two or three valve group, the roof of the short pipe of described level is provided with airflow hole, the diapire of the short pipe of level is provided with liquid flow hole, the other end of described liquid conductance pressure pipe is connected with described liquid flow hole, the other end of described air-flow connecting pipe is connected with described airflow hole.
Adopt the gas-liquid two-phase flow Pitotbar flow meter of said structure, owing to having set up level gauging device in pipeline, the pressure signal that the second differential pressure transmitter conductance pressure pipe gentle to liquid conductance pressure pipe transmits draws the pressure reduction of level short pipe liquid level upper surface and the short pipe liquid level of level minimum point, thereby can calculate the true altitude of the short pipe liquid level of level, the flow rate of liquid that draws according to bi toba flow sensor and the first differential pressure transmitter again can be measured the flow of liquid in the short pipe of level exactly.
