Wired remote water meters have been favored by many water supply management departments due to their good communication signals and high rate of meter reading. However, due to various reasons, water leakage problems sometimes occur in remote water meters. What is the problem with water leakage?
According to the technician, the main reason for the leakage of the remote water meter is that one line may be damaged, it can be connected to the ground, or the two lines are damaged and water is connected.
After the line is not completely broken, but the formed land, connected water, water, or signal line two branches are not completely connected through the water, causing leakage or incomplete short circuit will cause the collector power or current collector table reading abnormality To judge.
It is necessary to use a multimeter to detect the cause of the short circuit when the photoelectric direct reading water meter has long leakage. After investigating the above two cases, we usually use a multimeter to measure the resistance at the end of the line. If the resistance is in hundreds of Europe and thousands of Europe, then people suspect that it is not completely shorted. Leakage is very similar to short circuit and is an incomplete short circuit condition. Leakage can affect the meter's signal return to the collector, resulting in a collector or an abnormal reading that cannot be replicated.
Of course, the probability of water leakage from a remote water meter is very low. The above introduction just wants to tell you some information about the remote water meter. Don't worry too much.
