V cone flowmeter scale and orifice meter scale selection of design and calculation time pressure values

Abstract: the scale and the orifice meter scale V cone flowmeter selection of design and calculation time pressure value information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Key words: V cone flowmeter throttle orifice meter time difference pressure value production equipment manufacturers all know, in the orifice meter and V cone flowmeter throttle device according to the parameters, such as calculation of hole diameter, to such a problem, is the differential pressure change to send. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the scale and the orifice meter scale V cone flowmeter selection of design and calculation time pressure value article details. Keywords: V cone flowmeter throttle orifice meter time difference pressure value production equipment manufacturers all know, 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.

The importance of mass flow meter has increased as insertion ultrasonic flow meter have become a must in our daily life.

We believe our ability can raise a giant wave of innovation among the field of mass flow meter.

is something that has been around for a few decades now, enjoying it's heyday back in the endress hauser coriolis mass flow meter.

Beijing Sincerity Automatic Equipment Co., Ltd can promise you that we never conceded on the quality standards of our products.
