Which kind of smart water meter is good? The application of smart water meter
In our daily life, water resources are our essential energy. The price of water is determined by the degree of the water meter, so we often worry about whether the water fee will be calculated more. The emergence of smart water meters has solved this problem well. , Today we will take a look at the introduction of the smart water meter.
Electronic sensor of smart water meter: In the counting mechanism of the water meter, an electronic sensor is installed below the dial. The sensor rotates synchronously with the counting gear. The electronic information stored by the electronic sensor is completely synchronized with the mechanical reading of the water meter, forming a specific mathematical function relation. Using A/D conversion at the water meter collection terminal, the electronic information is directly displayed as the water meter reading.
Infrared sensor of smart water meter: Install an infrared sensor device at each position corresponding to the scale under the code plate of the institutional water meter. Inside the upper cover is equipped with a data processor composed of a CPU and a single-chip microcomputer. The infrared sensor on each scale will The scale display information is summarized to the processor and run through the program to display the water meter data.
IC card of smart water meter: IC card is used as the carrier. It inputs information into the water meter control system to determine the working status of the water meter, such as switch, recharge, etc. The main function is to use the IC card controller to realize the water meter prepaid application, that is, "first Buy water and use it later".
Photoelectric sensor of smart water meter: Install a photoelectric converter on the turntable of the mechanical water meter. There is a groove on the turntable. Every time the turntable rotates, the converter completes an electrical conversion and outputs a counting pulse.
Hall sensor of smart water meter: add Hall element and magnet to the mechanical water meter to form a sensor based on magnetoelectric conversion technology. The magnet installed on the counting plate rotates with the counting turntable and passes through the Hall element once. A counting pulse is output by the Hall element.
Reed switch sensor of smart water meter: Add a reed switch and a magnet to the mechanical water meter, and use the reed switch to cyclically open and close under the cyclic action of the magnet to output a metering pulse signal.
Regarding the smart water meter, Today will stop here. I hope it will be helpful to you.
