1. What should be noted when selecting a liquid flowmeter?

Liquid flow meters are used for measuring liquid flow rates. Commonly used liquid flow meters include electromagnetic flow meters, turbine flow meters, ultrasonic flow meters, V-cone flow meters, etc. For most operating conditions in the market, electromagnetic flow meters and turbine flow meters can meet various flow measurement needs. Below, electromagnetic flow meters will be selected.. For large-diameter flow measurement, when the diameter is generally ≥ 500MM, it is recommended to use a split type for maintenance convenience. When the instrument is installed below the ground, a split type IP68 structure must be selected. When the instrument inevitably needs to be installed at the pump outlet, a split type structure instrument should be selected. Key points for selecting liquid flow meters:

1. Installation form: There are usually three installation methods: flange type, clamp type, and insert type. The selection of installation method depends on the actual working conditions on site, and these three installation methods will not be affected by the current working conditions.

2、 Nominal diameter: Commonly used diameters include DN

10, DN1

5, DN3

2, DN40, DN50, DN65, etc., depending on the flow range and on-site conditions.

3、 Electrode form: There are generally three types of electrode forms, which can be divided into standard fixed type, scraper type, and detachable type.

4、 Electrode materials: In electromagnetic flowmeters, commonly used electrode materials include stainless steel 316L, Hastelloy HB, Hastelloy HC, titanium Ti, Ta, platinum Pt, tungsten carbide WC, etc., which need to be determine

5、 Lining material: Depending on the measuring medium, corrosive media and conventional water purification use different materials. Commonly used lining materials include chloroprene rubber (CR), polytetrafluoroethylene (F4), polyurethane rubber (PU), perfluoroethylene propylene (F46), Teflon (PFA), PO, etc.

6、 Rated pressure MPa: Select the flange size that meets the on-site working conditions according to different pressure values

6.3MPa | Suitable for DN10-DN1504.0MPa, suitable for DN10-DN1501.6MPa, suitable for DN200-DN5001.0MPa, suitable for DN200-DN100000.6MPa, suitable for DN1000-DN20000.25MPa, suitable for DN2000-DN3500

7. Output signal: The common output signal method on the market is 4-20mA, and the output methods in electromagnetic flow meters include 4-20mA, 4-20mA+HART, RS485

5. Pulse.

8、 Finally, regarding the installed power supply, the ambient temperature on site, whether it is a split or integrated type, and whether it needs to be explosion-proof, it is necessary to investigate the working conditions on site. Note: For the selection of liquid flow meters, the most important parameter is the measured medium. Based on the measured medium and range, you can know what kind of liquid flow meter is needed for measurement.
