1. What are the types of quality flow meters?
2. What is the reason why a devices flow meter does not display flow? The flowmeter is from Shanghai Automation. The background introduction is too simple to make a judgment. Firstly, it is necessary to know which type of flowmeter it is, whether it is electromagnetic, vortex street, or orifice plate; What is the reason for not displaying traffic? Is it a black screen in the header or is the data in the header always zero. The transmitter header is black. Please check the power connection. If there is no problem with the connection, please send the transmitter back for repair. If the LCD source display of the flow meter is always zero, there are several common situations: 1. The flow rate is too small. 2. The flow meter is installed upside down. 3. The pressure tube is blocked or the probe is malfunctioning. Sometimes the flow meter will have no display, and it will be normal after stopping the power supply. Can it be completely resolved. _A hundred ..
Do you mean that the entire LCD screen is out of battery or there is no display value showing up? The first situation requires checking whether the cable plug inside is loose; In the second scenario, first confirm whether the fluid flow rate or lead cover is also intermittent. Secondly, open the watch body and check if there is scaling or blockage of debris at the electrodes inside the watch body. Finally, check the wiring plug of the meter head again. If the current output is normal, it must have been caused by the loose plug during the excitation, resulting in the failure to display. If there is no current output, check whether the output board is faulty. If you are a newly installed flowmeter, you also nee
4. The on-site display of the differential pressure flowmeter is not showing on the computer
There is a problem with the transmitter and process pipeline.
. The differential pressure flowmeter does not display on the computer on site, which means there is no flow display value, and the transmitter has no current signal output. The reasons are as follows:1. There is a problem with the transmitter: the sampling valve is not open, the pressure pipe is blocked, the condensed water of the steam flow is not completely condensed, the drain valve is not closed, the power supply and connection cables of the transmitter are faulty, and the components of the transformer are damaged.
1、 There is a problem with the process pipeline: there is really no vertical blockage and fluid flow inside the process pipeline.
5. Reasons and solutions for no display or unstable readings of steam flow meters
The reasons and solutions for no display or unstable readings of steam flow meters are as follows:
1. Reasons and solutions for no instantaneous flow display and power supply and wiring problems: power supply not connected, poor or damaged cable connection (such as signal line mistakenly connected to the power supply end).
. Solution: Check if the power line is supplying power normally and confirm that the power voltage is stable. Check
