Smart water meters can be divided according to different classification standards, mainly including the following categories:
Classification by metering principle:
Mechanical water meter with electronic device: The metering principle of this type of water meter is the same as that of traditional mechanical water meters, but the mechanical reading is converted into electrical signal data through an electromechanical conversion device to realize remote communication and other functions. It mainly includes pulse type and direct reading type. The former works through magnetic sensing or non-magnetic sensing, and the latter collects signals through infrared photoelectric tubes, resistors or metal contacts.
Electronic water meter: This type of water meter does not contain mechanical moving parts. It measures flow through electromagnetic, ultrasonic, jet and other principles, solving the wear, two-way metering difficulties and error correction problems of mechanical water meters. The main types include ultrasonic water meters and electromagnetic water meters.
Classification by communication method:
Smart card water meter: It comes with collection, power supply, electric valve and card reading functions, which is easy to install and realizes charging first and then water use. Specifically, it includes wire-based smart IC card remote water meter, bus-based smart IC card remote water meter and wireless transmission smart IC card remote water meter.
Remote water meter: Uses microelectronics technology and automatic control technology to measure water consumption and calculate the usage price. This type of water meter achieves remote communication through data collectors and concentrators.
Classification by usage scenario:
Civil water meter: Mainly used in residential, office buildings, schools, hospitals and other places to calculate daily water consumption.
Industrial water meter: Suitable for industrial production departments, such as processing plants, chemical plants, etc., which require higher measurement accuracy and stability.
These classifications help users choose the appropriate water meter type according to specific needs to ensure the accuracy of measurement and convenience of use.
