1. Share the wiring method of the two-wire system for vortex flowmeter?

For the two-wire wiring method of the vortex flowmeter, please refer to the attached diagram. When you open the junction box, you can see a row of wiring terminals on the green circuit board. The first group is connected to the positive+24V power line, and the second group is connected to the current output signal accompanying wire. The two-wire wiring method here is 24V+and current I+. If this is a combination wiring, that is, the wiring method for the 4-20mA output of the two-wire system, be sure to pay special attention when wiring and do not connect it incorrectly.

1. Vortex flowmeter has certain requirements for the upstream and downstream straight pipe sections of the installation point, otherwise it will affect the flow field of the medium in the pipeline and affect the measurement accuracy of the instrument. The length requirements for the upstream and downstream straight pipe sections of the instrument are shown in the figure. Note: The regulating valve should not be installed upstream of the vortex flowmeter as much as possible, but should be installed at 10D downstream of the vortex flowmeter. 2. The inner diameter of the upstream and downstream piping should be the same. If there is a difference, the inner diameter Dp of the piping and the inner diameter Db of the vortex flow meter body should meet the following relationship: 0.98Db ≤ Dp ≤ 1.05Db. The upstream and downstream piping should be concentric with the inner diameter of the flow meter body, and the different axial degrees between them should be less than 0.05Db. 3. The sealing gasket between the instru

ment and the flange should not protrude into the pipe during installation, and its inner diameter should be 1-2mm larger than the inner diameter of the body. (3) Installation steps of the vortex flow meter: 1. Open the pipe according to the requirement of opening size, so that the opening position meets the requirements of the straight pipe section. 2. Place the entire flowmeter connected to the flange into the opened pipeline. 3. Perform spot welding positioning on both sides of the two flanges. Remove the flowmeter, weld the flange as required, and clean all protruding parts inside the pipeline. 4. Install a sealing gasket with the same diameter as the pipeline in the inner groove of the flange, install the flowmeter in the middle of the flange, and make the flow direction of the flowmeter the same as the fluid direction, then connect it with bolts. （4） Installation of flowmeter on horizontal pipeline: When measuring gas flow, if the measured gas contains a small amount of liquid, the flowmeter should be installed at a higher position in the pipeline. When measuring liquids, if the measured liquid contains a small amount of gas, the flowmeter should be installed at the lower virtual part of the pipeline. （5） Installation of flow meters in vertical pipelines: When measuring gases, flow meters can be installed on vertical pipelines with no flow restrictions. If the measured gas contains a small amount of liquid, the gas flow rate should be from bottom to top. When measuring the flow direction of a liquid, it should be from bottom to top.
