Orifice meter scale measures to ensure measurement accuracy

Abstract: the orifice meter scale measures to ensure accuracy of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. The orifice meter measuring, often because of some objective factors lead to the measurement error is bigger, the following will give you the main introduction to ensure accuracy of orifice flowmeter measurement under the main measures: 1, orifice flow meter are calibrated by Taiwan. Big. More flow meter manufacturers choose model price quote you are welcome to inquire, here is ensure measurement accuracy of orifice meter scale measures the article details. The orifice meter measuring, often because of some objective factors lead to the measurement error is bigger, the following will give you the main introduction to ensure accuracy of orifice flowmeter measurement under the main measures: 1, orifice flow meter are calibrated by Taiwan. As you all know, the standard orifice plate as long as the design and manufacture with reference to relevant standards, don't need 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, the orifice meter 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 orifice 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 orifice opening, 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. Orifice meter measuring 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, orifice meter 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. Orifice flowmeter for flow is actually 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. The orifice meter measuring, often because of some objective factors lead to the measurement error is bigger, the following will give you the main introduction to ensure accuracy of orifice flowmeter measurement under the main measures: 1, orifice flow meter are calibrated by Taiwan.
