Abstract: the integration of the orifice meter scale differential pressure value selection method of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Abstract: the integration of orifice meter is measured flow differential pressure generator, cooperate with all sorts of differential pressure gauge or differential pressure transmitter to measure all kinds of fluid flow in pipes. Throttling device including the ring chamber orifice, nozzle, etc. This paper introduces the integration of the orifice meter. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the integration of differential pressure value of the orifice meter scale selection method of the article details. Integration of orifice meter is measured flow differential pressure generator, cooperate with all sorts of differential pressure gauge or differential pressure transmitter to measure all kinds of fluid flow in pipes. Throttling device including the ring chamber orifice, nozzle, etc. This paper introduces the integration of differential pressure orifice flowmeter value selection method, for everybody reference. Integration of orifice meter is measured flow differential pressure generator, cooperate with all sorts of differential pressure gauge or differential pressure transmitter to measure all kinds of fluid flow in pipes. Throttling device including the ring chamber orifice, nozzle, etc. The throttle device with differential pressure transmitter, can measure the rate of flow of liquid, steam, gas, it is widely used in petroleum, chemical, metallurgical, power, light industry and other departments. Integration differential pressure value of the orifice flowmeter selection methods: instrument earlier as domestic development and production of orifice meter manufacturers, production quality, the integration of orifice flowmeter performance is remarkable, is widely applied in many domestic industrial field. Cone is the use of V V cone flowmeter in the flow field generated by the throttling effect, measured by detecting the differential pressure of upstream and downstream of the flow. Compared with ordinary throttling, it changed the throttling layout, from the center hole throttle annular throttle instead. Practice shows that compared with other flowmeters, V cone flowmeter has high accuracy, good stability for a long time, the installation condition limits small and wear resistance, wide measuring range, small pressure loss and suitable for the advantages of smudges. And V cone itself as the flow field of the rectifier and become a new type has unique properties of excellent flowmeter. By V cone combination sensor and differential pressure transmitter, V cone flowmeter can accurately measure the width of Reynolds number ( 8× 103≤ 再保险≤ 5× 107). Within the scope of all kinds of medium flow. All know production throttling device manufacturers, in the orifice meter and V cone flowmeter throttle device according to the parameters, such as the calculation of hole diameter, to such a problem, is the differential pressure transmitter zui big differential pressure value, the problem of how to choose? The differential value, how to select, how to choose? And many factors, such as uncertainty, such as straight pipe before and after, so in the calculation of orifice meter and V cone flowmeter open hole diameter, must not blindly choose large differential pressure, and to consider some factors. 1. The above basic introduction selection is the differential of the big advantages, development to a certain degree, however, will bring some disadvantages of relative. Familiar with orifice flowmeter and V cone flowmeter processing technology should be know, when a cop selection pressure is too large, so is a direct result, open hole is small, then the relative is the pressure loss is very big also, orifice flow meter was the pressure loss is very big, if coupled with this, so for the entire process system, due to the pressure loss cost is considerable. V cone flowmeter, by contrast, the moderate point slightly. 2. Differential pressure value, & beta; The value is smaller, it is recommended to use zui small Reynolds number is smaller. In this way, made it possible to actual Reynolds number greater than the recommended Reynolds number, so the flow coefficient tends to be stable, measurement precision is improved. 3. For differential pressure transmitter, differential pressure big contrast pressure little more stable. 4. Differential pressure is bigger, need zui smaller straight pipe can be shorter. Said according to the characteristics of the orifice flowmeter for integration, taking into account all aspects of economic factors, should choose the opening differential zui big value; The V cone flowmeter is relatively better, for the fluid is Newtonian fluid, the straight pipe requirements of V cone flowmeter is lower, even shorter, by contrast, does not exist. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
