Do you know what precautions should be taken when using a vortex flowmeter?

Proper use and installation are crucial for vortex air flow meters, as they reduce the probability of problems. Next, let flow meter manufacturer Qingtian Instrument explain the precautions for installing vortex flow meters..

1、 The flowmeter should be installed indoors. If it needs to be installed outdoors, measures should be taken to avoid direct sunlight and rain.

2、 Flow meters should be avoided from being installed in places with strong magnetic field interference, small space, and inconvenient maintenance.

3、 Flow meters should be avoided from being installed in environments with high temperatures, equipment thermal radiation, or corrosive gases. If installation is necessary, insulation and ventilation measures must be taken.

4、 Flow meters should be avoided from being installed on pipelines with mechanical vibrations. If installation is necessary, shock absorption measures must be taken, such as installing flexible hoses for transition, or installing pipeline fixing support points and shock-absorbing pads at 2DN upstream and downstream of the flow meter.

5、 After spot welding the flange and pipeline, the flowmeter should be removed and cannot be welded with the flowmeter.

6、 The flow meter can be installed 360 ° in any direction along the vertical axis of the pipeline. Installation method: The low-temperature medium meter pole is installed vertically on the ground; The high-temperature medium meter rod is installed parallel to the ground.

7、 Due to the sagging of the pipeline, it is easy to cause sealing leakage between the flowmeter and the flange. Therefore, the flowmeter

8、 In the pipeline measuring steam, in order to prevent the converter temperature from being too high, at least half of the instrument connecting rod should not be insulated.

9、 For the convenience of observation and wiring, the meter head of the flowmeter can be rotated 360 ° in its original position. After adjusting the position, tighten the locking nut. To prevent water vapor from entering the housing from the locking nut, it is necessary to wrap and seal the locking nut with waterproof tape if necessary.

10、 The direction of the shielded cable connecting the flowmeter should be kept away from places with strong electromagnetic field interference, and it is absolutely not allowed to be laid together with high-voltage cables. Shielded wires should be shortened as much as possible and should not be coiled to reduce distributed inductance, with a length not exceeding 500 meters. 1

1、 When wiring, first unscrew the back cover of the watch case and send the signal wire into the waterproof connector. Tighten the waterproof joint and ensure that the cable is bent downwards before entering the waterproof joint to prevent water from entering the housing along the cable.

2. What phenomena may occur if the air flow meter is broken? As an important component of the engine management system, the air flow meter plays a crucial role in monitoring the intake volume of the engine. It converts intake information into electrical signals and accurately reports to the ECU (Electronic Control Unit) to en
