What are some of the common failures that can be encountered with diesel flow meters?
2024-05-14
There are several types of diesel fuel flow meters on the market, today we have the elliptical transmission diesel fuel flow meter as an example, on daily use some of the defects that will occur, the transmission flow meter due to belong to the more complex instruments easily get out of the problem of most places inside, due to the internal work of the transmission diesel fuel on the flow of liquid cleanliness requirements, compared to the following solid particles will be stuck short, no flash or flash does not fix. Common defects and treatment methods are as follows:
1, flash on degree of compliance with a certain value without change
Fault handling methods: first determine whether there is a fault in the signal response system. Block the power supply to check whether the signal response circuit is connected to voltage normally. If faults are still present, you can clean the line filter. If the filter or piping is damaged, the flowmeter can be disassembled to check and remove contaminants. When disassembling, remember that both the upper and lower gears of the diesel fuel inlet device are also installed.
2, the degree of instability of the indicator
Disadvantages of the treatment method: check if the flow is flashing vibration system or perhaps hand on the diesel fuel transfer flow meter to see if the flashing readings have changed, if there is no change or perhaps magnetic weakening of the magnetic sensor of the flow meter, resulting in the inability to produce a limited response signal.
3, the flow rate is low when the error is relatively large
Disadvantages of the treatment method: wear or corrosion of the diesel drive shaft bushing caused by deformation of the flowmeter casing. At this stage, you can usually hear the flowmeter in operation clicking away.
4. The difference between error and practice is very large or small
Disadvantages of the processing method: the reason is that perhaps the liquid contains gas or the zero voltage signal is abnormal, the need to suspend the flowmeter new calibration work.
5、 Liquid leak
Disadvantages of the treatment method: elliptical gear diesel flowmeter leakage of this defect, certainly aging seals lead to leakage just need to replace seals on the line.
If you want to know more about the flow meter or flow meter selection, please consult the Aister flow meter manufacturer email: sales@aistermeter.com for help.
