1. How to select a flowmeter
1. Before selecting a flowmeter, the type and flow rate value of the measured medium (which can be an estimated value) should be determined, and then the specifications of the vortex flowmeter should be selected according to the flow range corresponding to the vortex flowmeter when measuring different media in the table.
2、 The flow rate of the measured medium in the pipeline must be within the flow range of the flowmeter, otherwise it cannot be used. It is best to be at 1/2 to 2/3 of the flow range of the flowmeter.
3、 If the actual diameter of the pipeline is larger or smaller than the selected diameter of the flow meter, a contraction tube or expansion tube should be used to reduce the diameter to ensure the correct use of the flow meter.
4、 Select the vortex signal output method based on the purpose of the vortex flowmeter: When the measured medium is a compressible fluid and the temperature and pressure changes of the medium on site are significant, it is recommended to use a vortex sensor with pulse signal remote transmission and a flow integrator with temperature and pressure compensation. Pressure transmitters, temperature transmitters, or Pt100 need to be purchased separately by the user. The flow meter is installed indoors with good environmental conditions and does not require remote signal transmission. It only needs to read the flow value on site, and the installation location of the flow meter is convenient for operation and data reading. Jianpeiyan recommends that users choose battery powered on-site direct reading vortex street flow meters. However, if the flowmeter is installed outdoors and exposed to the atmosphere, a battery powered on
5、 Select high or low temperature vortex flowmeters based on the temperature of the measured medium. High temperature models ranging from 250 ℃ to 350 ℃ are generally equipped with radiators.
6、 Explosion proof vortex flowmeter is selected for explosion-proof places.
