V cone flowmeter scale and orifice meter scale differential pressure value selection skills

Abstract: V cone flowmeter selection and differential pressure orifice meter scale values questionnaire technique information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. V cone flowmeter ( V - coneflowmeter） Is my company in the 1980 s began to develop a differentia pressure meter, it is the successful development of differential pressure type flow measurement of qualitative leap. It USES V cone in the flow field generated by the throttling effect, through the detection of upstream and downstream. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a V cone flowmeter scale and orifice meter scale differential pressure value select tip for details. V cone flowmeter ( V - coneflowmeter） Is my company in the 1980 s began to develop a differentia pressure meter, it is the successful development of differential pressure type flow measurement of qualitative leap. It USES V cone 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. 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. 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. Differential pressure value is big, need zui small straight pipe can shorter according to the characteristics of the for orifice meter, 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, there is no 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. Described above are all basic selection differential pressure when big advantages, but most of the time, development to a certain degree, will bring certain disadvantages. Familiar with orifice flowmeter and V cone flowmeter processing technology, should know that 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. So we in the process of production at ordinary times, can not blindly advice our customers choose big differential pressure value, to be really responsible for the customer, responsible for the enterprise. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
