With the development of science and technology, many equipment in our lives is also constantly being upgraded. In the field of water meters, traditional mechanical water meters have been replaced by more advanced photoelectric direct reading water meters and pulse meters. However, many people may not know the difference between these two water meters. This article will introduce the significant difference between photoelectric direct reading water meter and pulse meter.
Optical direct reading water meters and pulse water meters are two main types that have attracted much attention. They play an important role in water supply companies and are responsible for transmitting user data to computer terminals.
First of all, let's take a look at the optoelectronics direct reading water meter. Optical direct reading water meter is a device that uses optical principles to directly read the read number of water meter reading. It scans the water meter wheel through laser or infrared light, and then converts the scanned light signal to a telecommunications signal through a photoelectric converter, and finally obtains the readings of the water meter after processing through the electronic circuit. The advantage of photoelectric direct reading water meter is that the reading is accurate, it is not affected by the environment, and does not need to be manual meters, which greatly improves work efficiency.
Let's take a look at the pulse water meter. The pulse water meter is a water meter that calculates the water flow by detecting the pulse signal generated by the water flow. When the water flows through the water meter, the leaf rotation in the water meter will be pushed, and the rotation of the impeller will generate pulse signals. The pulse water meter calculates the flow of water by counting these pulse signals. The advantage of the pulse water meter is that the structure is simple and the cost is low, but its reading may be affected by factors such as water quality and pipeline pressure.
So, what are the significant differences between the photoelectric direct reading water meter and the pulse water meter?
First, the working principle of the two is different. Optical direct reading water meter is directly read the reading of the water meter through optical principles, and the pulse water meter is calculated by detecting the pulse signal generated by the water flow to calculate the water flow.
Secondly, the accuracy of the two reading is different. The accuracy of the readings of photoelectric direct reading water meters is very high, and it is almost not affected by any environmental factors. The reading of the pulse water meter may be affected by factors such as water quality and pipeline pressure.
Again, the cost of use between the two is different. The cost of photoelectric direct reading water meter is relatively high, but its high -precision and automation characteristics can greatly save the cost of manual metering. The cost of the pulse water meter is relatively low, but it needs to be maintained and calibrated regularly.
Finally, the service life of the two is also different. Due to the high accuracy and automation characteristics of photoelectric water meters, the service life is generally long. Due to the mechanical structure of the pulse meter, the service life may be affected by factors such as water quality and pipeline pressure.
