Is the photoelectric direct reading water meter okay? The use of the photoelectric direct reading water meter.
Hydropower engineering is one of the key points of our Daily life. Natural water meters are also a must-have product in our home life. Photoelectric direct-reading water meters have only appeared in recent years. How about photoelectric direct-reading water meters? Next, let's take a look!
Is the photoelectric direct reading water meter okay?
Directly read the word wheel data, compared with the traditional pulse meter, it can reduce the reading error to zero; adopts low-power design, only need to supply power when reading and valve switching; adopt advanced data encoding and verification technology, The communication reliability is high; it adopts the rotary-wing metering structure, which has high metering accuracy, convenient meter reading and beautiful appearance.
The working principle of photoelectric direct reading water meter
The photoelectric direct reading water meter adopts the photoelectric direct reading technology to read the word wheel data. Compared with the traditional pulse meter, it can reduce the reading error to zero. It is an electronic remote water meter with zero error of electromechanical conversion in the automatic meter reading system. Low power consumption design, no need to supply power normally, only need to supply power for meter reading or valve. The photoelectric direct-reading water meter adopts a rotary-wing measurement structure, which has the characteristics of high measurement accuracy, small starting flow, convenient meter reading, beautiful appearance, safety and health, and long life. The photoelectric direct reading water meter cooperates with the intelligent meter reading system equipment to complete the intelligent reading of the water, electricity, and gas meter data of the community, and realize the network data sharing with the settlement center.
Use of photoelectric direct reading water meter
1. The diameter of the water meter should be selected according to the flow rate of the installation site.
2. The installation location should avoid exposure to the sun, freezing, pollution, dampness and flooding in order to facilitate disassembly and meter reading. During freezing, in addition to wrapping the water meter and the water pipe, when not in use, close the valve at the inlet of the water meter, and open the drain valve and faucet at the outlet to prevent the water meter from being damaged due to frost expansion. It is recommended to install in a dedicated water meter box.
3. The water meter should be installed horizontally, literally facing up, and the arrow direction is the same as the water flow direction.
4. In the newly installed pipeline, the stones, sand, hemp and other debris in the pipeline must be washed clean before installing the water meter to avoid malfunction of the water meter.
5. For accurate measurement, the faucet should be higher than the water meter.
6. If the water meter is installed at the water inlet pipe of the boiler, the water meter should be prevented from being scalded by the backflow of hot water.
7. The water meter should not be directly connected to the pipeline, and the water meter and the pipeline should be connected through a pipe connection, a sealing gasket, and a connecting nut. When disassembling and assembling the water meter, do not force the hard plate to avoid twisting the case.
8. Avoid excessive stress on the water meter caused by pipes and fittings. When necessary, the water meter should be installed on the base or bracket.
9. Valves should be installed before and after the water meter to facilitate maintenance and replacement.
