What to consider when choosing a gas flow meter

Selection of gas flowmeter 1. The selection of gas flowmeter should consider the following three aspects: the type of flowmeter, the performance of the flowmeter, and the supporting equipment of the flowmeter. 2. The type of gas flowmeter should be selected according to the actual working conditions and the characteristics of the measured medium. 3. The following five elements should be considered in the performance selection of gas flowmeters: (1) Flow range; The flow range of gas flowmeters is related to applicable characteristics (continuous operation or intermittent operation), measurement accuracy and other factors. The same waist wheel gas flowmeter, when used for intermittent measurement, has a larger flow range (mainly because the upper limit flow can be larger than that of continuous operation); for measurement accuracy, when used for low-accuracy measurement, its flow range is larger , and for high-accuracy measurement, the flow range is small. In order to maintain the good performance and long service life of the meter, it is best to choose the working flow rate not to exceed 70%~80% of the maximum flow rate of the meter. (2) Measurement accuracy; The waist wheel gas flowmeter is one of the flowmeters with high measurement accuracy at present. The measurement accuracy given by the manufacturer on the product sample refers to the basic error obtained under the reference conditions of the laboratory. In actual use, due to the deviation of field conditions, additional errors will inevitably be brought. The actual error is the basic error and Composition of additional errors. Therefore, measures should be taken according to the problems that may occur on site when selecting the instrument. The on-site conditions have a greater impact on the measurement accuracy mainly due to the influence of the viscosity of the measured medium and the influence of temperature. (3) Pressure resistance performance (working pressure) The working pressure of the flowmeter must be borne by the working shell of the flowmeter. For different requirements of the working pressure, pressure parts of different materials should be used to avoid unsafe use. The highest shell pressure rating of conventional products can reach 1.0Mpa pressure. (4) Pressure loss; Pressure loss is also an important issue that must be considered when selecting a flow meter. Especially when using a large flow rate, more attention should be paid to checking whether the pressure loss of the gas flowmeter can meet the user's requirements. (5) Applicable purpose; The purpose of use refers to whether the flowmeter is used for trade settlement and cost accounting, or for process parameter control. The flowmeter used for accounting and measurement mainly considers whether its measurement accuracy meets the requirements of accounting, and according to user requirements, it should be equipped with various supporting equipment such as volume corrector, IC card controller, various signal output interfaces, and historical database. Function. Installation of gas flowmeter 1. Environmental conditions: There is no corrosive gas around, small mechanical vibration, little dust and far away from heat sources. For intelligent flowmeters equipped with volume correctors, there should also be a compliant electromagnetic environment. 2. Ambient temperature: generally not exceeding the range of -20°C~+80°C. 3. Pipeline conditions: Before installing the flowmeter, the pipeline must be cleaned and purged to remove all sundries, rust and dirt. The continuous pipeline should generally be coaxial with the same caliber as the inlet and outlet of the flowmeter, and no protrusion protruding from the pipe wall should protrude into the pipeline. The flowmeter should be installed without stress, fully considering the pipeline stress caused by the working temperature. The flow regulating valve, on-off valve and bypass valve installed in the circulation pipeline should work reliably, for example, if there is any leakage of the bypass valve, it will cause a serious drop in measurement accuracy. In order to facilitate observation and inspection, the cutoff of the bypass pipeline can be composed of two on-off valves connected in series. A small-diameter leak detection valve is installed on the connecting short pipe between the two valves, which can easily check the cutoff status of the bypass valve. As required, install appropriate temperature measuring instruments and pressure measuring instruments near the inlet of the gas flowmeter to determine the temperature and pressure of the gas to be measured.
