Any measuring instrument has an important indicator, which is accuracy. The same goes for flow meters, the higher the measurement accuracy, the better the benefits and safety generated in production. So when choosing a flowmeter, accuracy must be considered. Since precision is considered, it is necessary to consider various selection parameters.
When selecting rotary flow meters and float flow meters, factors such as temperature, pressure, measuring medium, density, flow range, and material can all affect measurement errors.
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 flow rate and value of glass rotor flowmeter and metal tube rotor flowmeter are both 10 times, and the commonly used flow rate is usually more accurate at around 60% of the flow range. Therefore, when selecting, this flow range should also be considered.
The third one is the medium. The density of the medium itself is also different, and some media are corrosive. When considering the selection of flow meters, the material must be taken into account.
In addition, other parameters of it need to be considered, such as its compressive strength, which are important factors affecting its operation.
Simply put, choosing a glass rotor flowmeter is not a simple task, and it requires a comprehensive analysis and consideration of the problem in order to select the correct flowmeter model and obtain the most efficient flowmeter.
