The vortex flowmeter produces the following causes: 1. The quality of the vortex street is not good; 2. The vortex street type is incorrect; 3. The vortex flowmeter is improperly installed; 4. The vortex flowmeter has interference signals on the spot; Vortex did not pay attention to maintenance. Vortex flowmeter failure Phenomenon : There is flow in the pipeline, but the flow is shown as 0 Vortex flowmeter failure phenomenon: There is no flow in the pipeline, but the display value is changing. Troubleshooting method: 1. Check if the instrument installation position is excessively vibrating. If the vibration is large, refer to page 10, 1 and 2 for shock absorption. . Vortex flowmeter failure phenomenon: LCD display shows a rapid increase in the rate of failure Troubleshooting: shutdown, restart. If it does not work, repeat it several times. Vortex flowmeter failure phenomenon; LCD display alternately bright or all black, the current output also jumps between the maximum and minimum. Troubleshooting: Shutdown, restart. If not, notify the factory. Vortex flowmeters have been developed over the years and their products have become more sophisticated, playing an important role in many steam trade measurements.
Water Cooling Tube For EV are used aluminum micro channel tubes with multi-port small channels to realize heat exchange cooling . It is a high efficiency battery management system solution for cylindrical cells. The cooling tube can be manufactured to meet the customer`s requirement in alloy,size,wall thickness ,geometry and batteries configuration. The micro channel cooling tube is with very low thermal resistance.When required for specific applications, we can do additional coating protection and thermal surface treatment.

Troubleshooting method: 1. Make sure that there is indeed flow in the pipe and is greater than the lower limit of measurable flow.
2. Check if the flow cutoff setting is too large.
3. If the pipe flow is normal, adjust according to the method on the first page (the flowmeter is zeroed on the field), and it will become output and display, indicating that the work is almost normal.
4. If there is still no output, the traffic still shows 0, and the cumulative amount does not change, indicating that the circuit board has a problem and should be considered for replacement.
5. If the cumulative value increases regularly in the fourth test, the problem lies with the sensor head.
6. Judging the sensor head is good or bad. Remove the two leads of the sensor head from the “S, T†terminals at the bottom of the rear circuit board, measure the resistance of the two lead wires of the sensor head with a multimeter, and the resistance of the two lead wires of the sensor head to the housing, respectively, should be greater than 2 MΩ. , otherwise need to replace the sensor head. If the sensor head is normal, then the rear circuit board will have to be replaced.
2. Turn the 6 (potentiometer) in Figure 10 clockwise to the magnification until the amplifier just has no output and zero the flow.
Vortex Flow Meter Failure Symptom: The LCD display is dim. Troubleshooting: Shutdown and restart. If not, notify the factory.
