Measuring instruments require precision, and flow meters are no exception. The higher the precision of measuring instruments and the more accurate the control of data, the more effective and safe it is in production. So when choosing a flowmeter, accuracy must be considered.
The most important factor in considering accuracy is the need to provide accurate selection parameters. When selecting a rotor flowmeter, factors such as temperature, pressure, measuring medium, and measurement range are involved, and any error in one of these factors can affect the measurement.
From the perspective of temperature and pressure, these two parameters have a significant impact on the density of gas. Gas is easily compressed, and changes in temperature, pressure, and medium density also occur. During the production process, flow meters are calibrated based on the parameters provided by customers. Errors may occur in measurements taken in different environments.
The second issue is the flow range, and the flow range should also be provided accurately. Do not assume that the larger the flow rate, the better for the same caliber flowmeter. The minimum sum of flow values for glass rotor flowmeter and metal tube rotor flowmeter is 10 times, and the commonly used flow rate is often more accurate at around 60% of the flow range. Therefore, when selecting, this flow range should also be considered.
What we also need to consider is its various other parameters, such as its compressive strength and the type of medium, which are important factors affecting its operation.
Based on the above analysis, the selection of a rotor flowmeter is not a simple task, but requires a more comprehensive analysis and consideration of the problem in order to obtain a better usage result.
