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 |
