How to guarantee the measurement accuracy of flow meter scale

Abstract: how to guarantee the measurement accuracy of flow meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. The flow measurement accuracy refers to the flow measurement system for precision, it there is a difference between with the accuracy of the meter itself. Flow meter itself only good performance, high precision, is not necessarily can obtain higher measurement accuracy. To ensure that the flow measurement system. More flow meter manufacturers choose model price quote you are welcome to inquire, here is how to guarantee the measurement accuracy of flow meter scale article details. The flow measurement accuracy refers to the flow measurement system for precision, it there is a difference between with the accuracy of the meter itself. Flow meter itself only good performance, high precision, is not necessarily can obtain higher measurement accuracy. To ensure the accuracy of the flow measurement system, in addition to the reasonable selection, correct installation and debugging, timely maintenance and maintenance, the application of intelligent technology to measure part may introduce errors are just the right amount of compensation and correction is also an effective method. To compensate the temperature of the liquid expansion coefficient, for example, to compensate the temperature, pressure and compressibility of the gas, the Reynolds number effect of differential pressure flowmeter and to compensate flow beam expansion coefficient, for a variety of compensation for the nonlinear of the flow coefficient of the flow meter, the displacement meter, the compensation for the temperature of the vortex flowmeter, the compensation for the velocity distribution of the ultrasonic flowmeter, etc. This compensation and correction, with the method of the system will detect some inherent, relying on its own cannot be overcome the error of processing, to eliminate or get basically eliminated. Practice shows that this method is simple and effective, is very promising. In the method ensures that the measurement accuracy of, occupies an important position in the online real flow calibration. Used mostly by adopting the method of off-line calibration flow meter, the use of this method after error correction calibration of flowmeter while the accuracy is higher, but because of its verification reference condition of the line and the actual use is different, when the verification when there are differences between the fluid properties and the actual use of the fluid, verification of environmental conditions and instrument use place of the actual environment different, resulting in the use of additional error, reduce the measurement accuracy. Online real flow calibration method is an effective method to solve this problem. Oil metering station in the construction phase, for example, set aside the standard volume tube connectors, access standard volume tube, through the valve switch can realize the machines in the metering station real flow meter to realize on-line calibration. Now, in the distribution of the gas station is also require the use of online real flow calibration method. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

Currently there is a global trend growing. People are more conscious about endress hauser ultrasonic flow meter and are seeking alternatives to traditional solutions.
