4. Installation And Usage for the Remote Reading Water Meter

Select the right water meter according to nominal flow rate which is less than or next to the rate through the pipe. It is not a good way for the user to buy the water meter based on the pipe size.

The place to be installed should be free from sunshine, frost,  pollutant and water. During the period of frost, the inlet valve in the meter should be closed and the outlet valve and water tap should be open except for being packed for thermal insulation, thus to prevent the damage from being frozen.

Meter should be installed horizontally, and the digits on the dial is up to the face and arrow direction in the meter should be same with the flow.

The stone, sand and slight impurities in the new installed pipe should be cleared off for the sake of the meter fault.

For the purpose of metering accurately, the water tap should be higher than the meter.

Water meter should be not connected with pipe and there are live interface (e.g. pipe interface, connection screw, sealing washer etc.) between the meter and pipe. The meter should not be damaged due to the over-stress caused by pipe and its elements during installation.

Comparison  of 2 type Remote reading water meter

Comparison
Pulse Output Water Meter Photoelectric Direct Reading Water Meter
Electromagnetic interference Pulse signal susceptible to external electromagnetic interference during transmission Materials not magnetic sensor, Meter Reading data instantly, without outside electromagnetic interference
Power Must maintain uninterrupted power supply, the loss of power will cause the system to data errors Systems usually do not work, no electricity, no power ,when reading the meter ,the power will supply ,after reading it will stop supply power
Meter reverse when water supply is cut off  ,the meter will possible reversal and couse secondary pulse signal, resulting in measurement error Directly read the pointer value or the figure show on the meter face plate, without water meter reverse impact
Demagnetization phenomenon With the extension of the use of small magnets,it will appear demagnetization ,can not send out the output pulse normally, resulting in an error Direct-reading meter, the sensor is not magnetic material, there is no demagnetization phenomenon
Accuracy Due to the above reasons, resulting in inconsistencies of the reading data between the meter and the computer shows Direct-reading meter reading similar way as the human eye, so between the meter shows the number of data and computer keep the same.
Price Cheap expensive
