Introduce the correct measurement measures for the electromagnetic flowmeter

The requirements of electromagnetic flowmeters to pay attention to the needs of on-site measurement often lead to errors in the measurement process due to some objective factors, so the results of measurement will not be accurate. Therefore, we need When using the electromagnetic flowmeter, it is necessary to take measures to maintain the accuracy. So, what are the ways to make better guarantees? Xiaobian made relevant introductions for electromagnetic flowmeters:

Everyone knows that the normative design and manufacturing can refer to relevant specifications and can be directly applied without the need for real-flow calibration. Since the outflow coefficient can be directly calculated by the software, but the computer calculation is more ideal than the ideal one, and the on-site environment is still somewhat different. Therefore, in order to ensure the measurement accuracy, it is recommended to stop the flow calibration for each flow meter and calibrate the outflow. The coefficient and the calculation result stop the comparison, calculate the difference, and stop the correction.

The influence of temperature on the electromagnetic flowmeter and its correction, the change of fluid temperature causes the change of density, which leads to the change of the relationship between differential pressure and flow. Secondly, the temperature change causes the inner diameter of the pipe, the change of the opening of the orifice, and the change of temperature. The correction is to take the temperature meter to measure the temperature of the field and then input it into the secondary meter to correct the error caused by the temperature change.

Each element is the element of the demand thinking, and all-round thinking will reduce more errors in the process of measuring and making it more standardized.
