2. How does the water meter measure?
The water meter measures the number of rotations of the turntable driven by the flow of water.. The following is a detailed explanation about water meter measurement: Working principle: There is a turntable inside the water meter, and when water flows through the water meter, it will drive the turntable to rotate. The water meter achieves measurement function by recording the number of rotations of the turntable and converting it into the corresponding water flow rate. Water meter types: Water meters are mainly divided into two types: volumetric water meters and velocity water meters. A volumetric water meter measures the volume of water flowing through it, while a velocity water meter calculates the water flow rate by measuring the water flow velocity and time. Water meter structure classification: Wet water meter: The counter is immersed in water, and its glass is subjected to water pressure. The transmission between the sensor and the counter is gear linked. The quality of water may affect the clarity of the reading on the water meter. Dry water meter: The counter is not immersed in water, the sensor is isolated from the chamber of the counter, the glass of the water meter is not subjected to water pressure, and the transmission of the sensor and counter is generally driven by magnetic steel. This type of water meter can avoid the influence of water quality on readings. Liquid sealed water meter: The digital wheel or the entire counter used for meter reading is sealed with a certain concentration of glycerol or other liquid, and the clarity inside the sealed and isolated counter is not affected by external water qua

3. [5 · 20 World Metrology Day] Water Meter Measurement Tips
Water meters are the main measuring instruments used to measure the flow of tap water through pipelines. Their accuracy is closely related to peoples livelihood interests and socio-economic development. Here are some water meter measurement tips: Types of water meters are classified according to measurement principles. Mechanical water meters can be divided into speed water meters and volumetric water meters.
. Among them, typical speed water meters include rotary wing water meters and spiral wing water meters. Water meter with electronic device: Adding electronic device on the basis of traditional water meter, it has more functions. Electronic water meter: using electronic measurement technology to achieve more accurate flow measurement. Special function prepaid water meter: Based on a regular water meter, equipped with a controller and an electric control valve, it has preset functions. The typical product is an IC card water meter. Users need to recharge first, and the fee will be deducted from the card when using water. When the balance is insufficient, the electric control valve will automatically close to stop the water supply. Remote transmission water meter: Using a regular water meter as the base meter, it has remote tran
