Abstract: how to improving the measuring accuracy of V cone
flowmeter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
V cone flowmeter field measurement, often because of some objective factors lead to the measurement error is bigger, the following will give you assurance of V cone flowmeter measurement precision are introduced the main measures: 1, V cone flowmeter calibration by Taiwan.
Everyone know.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is how to improving the measuring accuracy of V cone flowmeter scale article details.
V cone flowmeter field measurement, often because of some objective factors lead to the measurement error is bigger, the following will give you assurance of V cone flowmeter measurement precision are introduced the main measures: 1, V cone flowmeter calibration by Taiwan.
As everybody knows, V cone as long as the design and manufacture with reference to relevant standards, don't need a real flow calibration can be used directly.
Because of outflow coefficient can be directly calculated by the software, but after all, the ideal of the computer, and the scene environment still have certain difference, so, in order to guarantee the accuracy of measurement, suggestion to real flow per meter calibration, the calibration of the outflow coefficient and compare the calculated results, calculate on business value, modification.
2, Reynolds number correction, V cone flowmeter has a certain relationship between discharge coefficient and Reynolds number, when the mass flow rate change is directly proportional to the Reynolds number changes, thus cause the change of the flow coefficient.
3, the influence of temperature on the V cone flowmeter and its correction, fluid density changes with the temperature change, leading to the relationship between the differential pressure and flow change, secondly, pipeline diameter caused by the temperature variation, the change of the V cone hole, correction of temperature change, is to take temperature instrument measuring temperature field and then enter into the secondary instrument to adjust temperature change caused by the error.
4, expansiveness correction.
V cone flowmeter measurement of steam, gas flow, must carry out the expansiveness of correction fluid, specific design manual correction factor can consult the throttle device.
5, the calculation of steam mass flow rate, V cone flowmeter measuring, steam flow value, first by the differential pressure signal obtained by steam temperature, the pressure value look-up table density, to calculate the quality of the steam flow.
Actually V cone flowmeter for flow is to our application is very extensive, was also the representative of the differential pressure flowmeter, everyone can through appropriate inference to promote other differential pressure type flow meter.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
The increasing consumption demand in key segments such as low flow turbine flow meter, v shape
