The flow rate of the measured medium in the pipeline must be within the flow range of the flow meter, otherwise it cannot be used.
How to select a vortex flowmeter with a supervisory inspection certificate? I believe many people have encountered this problem. Today, Supmea Measurement and Control, a flowmeter manufacturer, will share with you its flowmeter selection experience.
The flow rate of the measured medium in the pipeline must be within the flow range of the flow meter, otherwise it cannot be used. It is best to be at 1/2 to 2/3 of the flow range of the flow meter. If the actual pipe diameter is larger or smaller than the selected flow meter diameter, shrink tube or expansion tube diameter reduction should be used to ensure the correct use of the flow meter.
① When the measured medium is a compressible fluid, and When the temperature and pressure of the on-site medium change greatly, it is recommended to use a vortex sensor with pulse signal remote transmission and a flow totalizer, pressure transmitter, and temperature transmitter with temperature and pressure compensation. ② The flowmeter is installed indoors with a good environment and does not require remote signal transmission. It only needs to read the flow value on site. The installation location of the flowmeter is convenient for operation and data reading. It is recommended that users choose a digital vortex flowmeter. ③When the installation environment of the flow meter is poor or the installation location is not convenient for on-site reading of flow values or centralized management, it is recommended to use a sensor that outputs pulse signals and is equipped with a flow totalizer, or a vortex meter with a 4~20mA standard current output. Street transmitter. ④When it is necessary to observe the flow rate on site and transmit signals remotely, it is recommended to use a digital vortex transmitter with a 4~20mA output. ⑤ When there is no need for on-site reading and only standard signals are transmitted remotely, it is recommended to use a vortex transmitter with a 4~20mA standard current output.
High-temperature models of 250℃-350℃ are generally equipped with radiators. Use explosion-proof vortex flowmeters in explosion-proof places.
The above is a brief selection method. Actual selection must refer to specific working conditions to understand factors such as accuracy, pressure level, connection method, and anti-vibration selection. In fact, when users have needs for selection, they can make selections based on the manufacturer's recommendations. Supmea Measurement and Control’s pre-sales service has professional technical service personnel to help users select flow meters and build metering solutions. After-sales services will also provide guidance on site selection, installation, etc. Users do not need to worry about flow meter selection at all. and installation issues.

The thermal mass flow meter is designed based on the principle of thermal diffusion. The instrument uses the constant temperature difference method to accurately measure the gas. It has the advantages of small size, high degree of digitization, convenient installation and accurate measurement. Reduce your energy costs and increase your sustainability. Monitor your consumption and analyze your leakage flows with just one measuring device.
Mass Flow Meter is a new type of advanced flow measurement instrument and has been rapidly developed in the world. It has been widely used for process detection and custody transfer measurement in many industries such as petroleum, petrochemical, chemical, pharmacy, marine, pharmaceutical, municipal, paper, food and energy and so on. It has been highly valued by the flow research community and welcomed by users at home and abroad.
