Abstract
The utility model discloses a pitotbar flow sensor for liquid with air and impurities. The pitotbar flow sensor for the liquid with the air and the impurities comprises a horizontal short round tube and a pitotbar flow sensor. A round hole is formed in the top wall of the horizontal short round tube. An inserting tube of the pitotbar flow sensor is inserted into the horizontal short round tube from the round hole. The pitotbar flow sensor is provided with a total pressure tube and a static pressure tube. The total pressure tube and the static pressure tube are respectively connected with a first air collector and a second air collector. Side walls of the first air collector and the second air collector are respectively connected with a first pressure guiding tube and a second pressure guiding tube. A first vent valve and a second vent valve are respectively arranged on the top portions of the first air collector and the second air collector. Due the fact that the air collectors are additionally installed on the pitotbar flow sensor for the liquid with the air and the impurities, flow of liquid can still be accurately measured when the liquid transported by pipelines is mixed with a little air and impurities.
Description
Technical field
The utility model relates to a kind of bi toba flow sensor of measuring fluid flow in pipeline, especially relates to a kind of bi toba flow sensor for gassiness, contaminated liquids.
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 mainly is made of bi toba flow sensor and differential pressure transmitter, bi toba flow sensor has the short pipe of level, the roof of the short pipe of level has circular hole, the intubate of described bi toba flow sensor is inserted in the short pipe of level from circular hole, bi toba flow sensor has ram-air pipe and static tube, ram-air pipe is connected with differential pressure transmitter with static tube when measuring the pipeline fluid flow, the bi toba flow meter of said structure is when measuring the pipeline fluid flow, be mixed with sometimes a small amount of gas and solid impurity in the liquid of pipeline, a small amount of gas can enter into ram-air pipe and static tube by the intubate that Pitot clings to sensor, enter into afterwards differential pressure transmitter, will there be certain error between the differential pressure of the total head that obtains of differential pressure transmitter and static pressure and actual differential pressure like this, cause the flow of the liquid that records at last inaccurate.
The utility model content
The technical problems to be solved in the utility model is to provide the bi toba flow sensor that is used for gassiness, contaminated liquids that still can accurately measure fluid flow when a kind of liquid when Pipeline transport is mixed with a small amount of gas and solid impurity.
for solving the problems of the technologies described above, the utility model is used for gassiness, the bi toba flow sensor of contaminated liquids, comprise the short pipe of level and bi toba flow sensor, the roof of the short pipe of described level has circular hole, the intubate of described bi toba flow sensor is inserted in the short pipe of level from circular hole, bi toba flow sensor has ram-air pipe and static tube, described ram-air pipe and static tube are connected with respectively the first gas collector and the second gas collector, the sidewall of the first gas collector and the second gas collector is connected with respectively the first connecting pipe and the second connecting pipe, the top of described the first gas collector and the second gas collector is respectively equipped with first row air valve and second row air valve.
adopt the gassiness that is used for of said structure, the bi toba flow sensor of contaminated liquids, because described ram-air pipe and static tube are connected with gas collector, when in ram-air pipe and static tube, gas being arranged, gas can float and be collected in gas collector, by vent valve, the gas discharging in gas collector is fallen when in gas collector, gas content reaches certain limit, thereby can guarantee the accuracy of the differential pressure of the total head of liquid in pipeline that differential pressure transmitter draws and static pressure, described bi toba flow sensor is inserted by the roof of described short pipe, the impurity that liquid contains can not stop up bi toba flow sensor, therefore the utility model finally can accurately measure the flow of liquid in pipeline.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation that the utility model is used for the bi toba flow sensor of gassiness, contaminated liquids.
Embodiment
referring to Fig. 1, the utility model is used for gassiness, the bi toba flow sensor of contaminated liquids, comprise the short pipe 10 of level and bi toba flow sensor 20, the roof of the short pipe 10 of described level has circular hole 11, the intubate 21 of described bi toba flow sensor 20 is inserted in the short pipe 10 of level from circular hole 11, bi toba flow sensor 20 has ram-air pipe 22 and static tube 23, described ram-air pipe 22 and static tube 23 are connected with respectively the first gas collector 1 and the second gas collector 2, the sidewall of the first gas collector 1 and the second gas collector 2 is connected with respectively the first connecting pipe 3 and the second connecting pipe 4, the top of described the first gas collector 1 and the second gas collector 2 is respectively equipped with first row air valve 5 and second row air valve 6.
