The pulse remote transmission water meter is an intelligent water meter that converts the water consumption of a mechanical water meter into pulse signals and can be transmitted over long distances. It combines the stability of traditional mechanical water meters with the intelligence of modern electronic technology and is widely used in smart water management.

• Low cost: The additional cost on the basis of mechanical watches is very little, and it is one of the lowest initial hardware costs among all remote transmission solutions.
• Simple technology, easy to understand: The principle is intuitive, and the installation and maintenance threshold is relatively low.
• Retains mechanical reading: As a backup for electronic data, when the electronic system fails, the mechanical dial can still be read manually as a reference.
• Solves some automatic meter reading problems: It has achieved a preliminary leap from "pure manual household visits" to "remote automatic collection".

• Residential water use: Very common, it is the first choice for many new residential areas and smart buildings.
• Commercial and industrial water use: Suitable for office buildings, shopping malls, factories, schools, hospitals and other places with large flow rates and high requirements for measurement accuracy.
• Urban water supply network monitoring: Can be used for district metering (DMA) of water supply networks, monitoring the total water consumption of the area, and promptly detecting leaks and losses.

Pulse remote transmission water meters are an important "explorer" in the development history of smart water meters. They initially achieved the function of remote meter reading at a relatively low cost. However, the technical principle based on pulse accumulation has brought about an intractable problem of data reliability that cannot be eradicated. This makes it an outdated and gradually phased-out technology in the modern smart water management system that pursues data accuracy and refined management. Understanding and recognizing its principle and shortcomings can help us better understand why the current market firmly chooses more advanced technical routes such as LoRa/NB-IoT direct reading meters or ultrasonic water meters.
