1. What pressure does the spiral vortex gas flowmeter display?

The common Ziyou instrument series intelligent spiral vortex gas flowmeter adopts the latest microprocessor technology, which has the advantages of strong functionality, wide flow range, easy operation and maintenance, and convenient installation and use. The main technical indicators have reached the advanced level of similar foreign products. Widely used in various gas metering industries such as petroleum, chemical, power, metallurgy, and coal. The following is a brief list of the causes and solutions for the malfunction of the head of the vortex gas flowmeter.

1. The instantaneous flow rate and pressure displayed on the head of the vortex flowmeter are normal, but the temperature display does not match the temperature at the work site.

The temperature reading is "-75C" or exceeds "100 ℃". The temperature sensor is damaged. The sensor can be replaced. 2. If the temperature reading exceeds or falls below the actual temperature on site, the phenomenon persists even after replacing the sensor. The temperature and voltage circuit is damaged. The temperature and voltage circuit can be replaced.

2. There is no display on the head of the vortex flowmeter. 1. The flowmeter does not have a 24V power supply or battery power supply. Provide 24V power to the flowmeter or replace the flowmeter battery. 2. The traffic meter LCD panel is damaged. Replace the flow meter LCD panel. 3. The flowmeter motherboard is damaged. Replace the flowmeter motherboard. 4. The power wiring is incorrect or disconnected. Find and rewire.

3. The temperature and instantaneous flow rate displayed on the head of the swirl gas flowmeter do not match the actu

al working pressure indication If the pressure reading is "80" or the "pressure upper limit" of the flowmeter (the upper limit can be found in the flowmeter selection reference table). One is to connect a new pressure sensor externally and check if the meter displays the local atmospheric pressure. If it displays the local atmospheric pressure, the original sensor is damaged. The pressure sensor can be replaced. The second is to connect half of the new pressure sensor externally. If the meter head still displays "80", it indicates that the flowmeter motherboard is damaged. The flowmeter motherboard can be replaced. 2. The pressure reading is basically a certain value (the on-site working pressure changes greatly, and the flowmeter head shows no or little change in pressure). One issue is that the pressure sensors pressure sensing hole is blocked. The pressure tapping hole can be cleaned. The second issue is the deterioration of the linear calibration curve of the pressure sensor. The pressure sensor can be replaced or recalibrated.

4. The temperature and pressure displayed on the head of the vortex flowmeter are normal, and there is no instantaneous flow display.

Choosing too many flow meters can result in no flow display. One is to lower the lower cutoff frequency of the flowmeter (so that the flowmeter can be used, but it will cause a decrease in the accuracy of the flowmeter). The second is to replace the small-sized flowmeter. 2. The preamplifier has no current input. The flowmeter is not powered by a power source, and can be powered by a 24V external power source or battery. 3. The preamplifier has no frequency output. The preamplifier can be replaced. 4. The main vortex flowmeter plate is damaged and mis
