The communication method of ultrasonic water meter
The ultrasonic water meter is a new type of water meter based on the principle of ultrasonic time difference for flow measurement and display. The meter is equipped with an M-BUS interface by default and can form a remote meter reading management system through the M-BUS bus and other communication equipment.
So what are the principles when choosing a communication method, and what are the functions and advantages of each communication method?
Let's talk about the various communication methods of ultrasonic water meters in detail.
We often use the M-BUS communication method, which adopts the wired communication form to collect the user's water consumption data through the collector, and then transmit the user's water consumption-related information to the water meter service management cloud through the M-BUS bus transmission method. The staff can Relevant operations and management are carried out with the help of the management system.
Modbus has the following features:
(1) The standard is open, and users can use the Modbus protocol for free and with confidence, without paying any fees, and without infringing intellectual property rights.
(2) Modbus can support a variety of electrical interfaces, such as RS-232, RS-485, TCP, etc., and can also be transmitted on various media, such as twisted pair, optical fiber, wireless, etc.
(3) The frame format of Modbus is simple, compact, and easy to understand. Easy for users to use, quick for manufacturers to develop, and simple for water management
Ultrasonic remote water meters use advanced ultrasonic flow measurement technology to measure the flow of water flowing through pipes. It can store water records for nearly 18 months, which is convenient for users and management departments to view.
The ultrasonic water meter adopts a wireless transmission form, without wiring or construction, which will not damage the user's decoration, but also realizes flexible data transmission, allowing users to feel the fun of wireless. Under normal circumstances, the coverage of ultrasonic water meters is much wider than that of M-BUS technology, the signal transmission and reception are more stable, and it can “walk through” dense buildings or open areas. Users bring better meter reading and management methods, making it more convenient for people to use meters.
Ultrasonic communication methods include M-BUS, 485, or wireless communication interfaces, users can choose the appropriate communication method according to their own needs.
