Due to the influence of flowmeter operating conditions, if the flowmeter malfunctions to ensure that the production task will have a certain impact, at this time it will need to be able to deal with the problem as soon as possible and resume use. The following technical Xiaobian of Heshun Flowmeter will share with you the common faults and treatment methods of swirling into the vortex flowmeter for your reference:

First, precession vortex flowmeter head shows instantaneous flow, pressure is normal, temperature display does not match the temperature of the work site

1. The temperature indicates "-75C" or exceeds "100°C".

The temperature sensor is damaged. Replaceable sensor.

2. The temperature indication is above or below the actual temperature of the site. After the sensor is replaced, the phenomenon remains.

The temperature and pressure circuit is damaged. Replaceable temperature and pressure circuit.

Second, precession vortex flowmeter meter without display

1. The flow meter does not have 24V power supply or battery power. Supply 24V power to the flowmeter or replace the flowmeter battery.

2. The flow meter panel is damaged. Replace the flow meter LCD panel.

3. The flowmeter board is damaged. Replace the flow meter board.

4. The power supply is connected incorrectly or disconnected. Find and reconnect.

Third, precession vortex flow meter header temperature, instantaneous flow display, pressure does not match the actual working pressure indicator

1. If the pressure indicator is "80" or the flow meter "upper pressure limit" (the upper limit can be found in the flow meter selection reference table).

One is to connect a new pressure sensor to see if the meter shows the local atmospheric pressure. If the local atmospheric pressure is displayed, the original sensor is damaged. Replaceable pressure sensor. The second is the external half of the new pressure sensor. If the meter still shows “80”, it proves that the flowmeter motherboard is bad. Replaceable flow meter board.

2. The pressure indication is basically a certain value (the on-site working pressure changes greatly, the flowmeter meter shows no change in pressure or changes).

One is that pressure sensors take pressure holes. Can clear the pressure hole. The second is that the linear calibration curve of the pressure sensor deteriorates. The pressure sensor can be replaced or recalibrated.

Four, precession vortex flow meter head shows normal temperature and pressure, no instantaneous flow rate display

1. The flow meter selection is too large. The over-selection of the flow meter will cause the flow meter to display no flow. One is to lower the lower cutoff frequency of the flowmeter (this allows the flowmeter to be used, but it will cause the flowmeter to be less accurate). The second is to replace the small size flowmeter.

2. The preamplifier has no current input. The flowmeter has no power supply and is used for 24V external power supply or battery power supply.

3. The preamplifier has no frequency output. Replaceable preamplifier.

4. The main precession vortex flowmeter board is damaged. Replaceable flow meter board.

The above are the common faults and solutions to the precession of vortex flowmeters. Please also pay attention to contact the manufacturers in time to ensure the normal use of the flowmeter as soon as possible. As a professional R&D flowmeter manufacturing enterprise, Heshun Flowmeter manufacturers have been persisting in the production concept of “quality and brand” and “brands and development” for the past few years. They persist in making unremitting efforts to tackle difficult problems and constantly research and develop new technologies and products. Our customers provide products with reliable quality and conform to the demand. At the same time, we have established a long-term cooperation relationship with many production companies. All colleagues of Heshunda look forward to working with you to set sail.
