Note
Choose the right model and size to meet the needs of your irrigation system.
Pipes need to be cleaned before installing the water meter to avoid the effects of dust and debris on the meter's performance.
Install and connect the water meter properly according to the manufacturer's recommendations and make sure it is securely fastened.
In daily use, do not apply excessive pressure or force to the water meter to avoid damaging it.
For water meters that have not been used for a long period of time, operations such as opening and flushing need to be performed to ensure that they are working properly.
Water meters need to be calibrated regularly to ensure their measurement accuracy.
Pay attention to water quality issues. Poor water quality or the presence of large amounts of impurities such as particulate matter may affect the accuracy and life of the irrigation water meter.
It is recommended that the condition of water meter pipes and valves be checked at least once a year so that problems can be identified and addressed in a timely manner.
