Introduction to the difference between rotary wing water meter and screw wing water meter
Rotary wing water meter and screw wing water meter are two commonly used water meters in daily life. They mainly use modern microelectronic technology, sensor technology, smart IC card technology, etc. to measure water consumption, transfer water data and settle transactions. However, many customers often ask "what is a rotary wing water meter", "what is a screw wing water meter", "what is the difference between the two" when purchasing, in order to answer customers' questions quickly and concisely , To improve customers' purchase efficiency, we will summarize the answers to the questions for customers' reference.
Rotor-type water meter: It is mainly composed of a casing, an impeller measuring mechanism, a reduction mechanism and an indicator. A water meter with a rotorcraft structure powered by a propeller. The water flow tangentially impacts the impeller from the water inlet of the case to make it rotate, and then passes through the gear reduction mechanism. The number of revolutions of the impeller is continuously recorded, thereby recording the cumulative flow through the water meter.
Screw-wing water meter: It is a kind of speed-type water meter. The rotating screw is used to drive the pointer to rotate. When the water flows into the water meter, it will impact the water meter along the axial direction and the screw-shaped impeller rotates and flows out. The speed of the impeller is proportional to the speed of the water flow. Proportional, after being driven by the reduction gear, the total amount of water passing through the water meter will be displayed on the indicating device.
The difference between the rotary wing water meter and the screw wing water meter mainly includes the following four aspects:
1. Appearance
The rotor-type water meter looks like the letter "O"; the spiral-wing water meter looks like the letter "I",
2. Function
The rotor-type water meter has simple structure, large flow capacity, good wear resistance and high measurement accuracy; the screw-type water meter has a wide working range, large flow capacity, small pressure loss, convenient installation and maintenance, but low sensitivity and low measurement accuracy.
3. Installation direction
The rotation direction of the impeller of the rotor-type water meter is vertical to the direction of water flow, and it is installed vertically during installation; the rotation direction of the impeller of the screw-wing water meter is horizontal to the direction of water flow, and it should be installed horizontally during installation.
4. Usage scenarios
The rotor-type water meter is suitable for the measurement of the total amount of one-way water flow in small-diameter 15mm and 20mm pipes. It is often used in the measurement of small and medium flow in small and medium-sized pipes in water supply projects, and the measurement of household water consumption.
Spiral wing water meters are suitable for measuring water flow in large-diameter DN80-DN200 pipelines. They are often used in water use scenarios such as factories, schools, and farmland irrigation. They can meet the measurement needs of water supply main pipelines and large factories and mines.
