What Are The Characteristics Of The Rotor Water Meter？
Rotor-type water meter: The rotor-type water meter has a narrow working range, large volume, inconvenient installation and maintenance, and high sensitivity. It is suitable for the measurement of the total amount of one-way water flow in small-diameter pipes. For example, domestic water consumption is measured by a water meter through small pipes with diameters of 15mm and 20mm. This water meter is mainly composed of a casing, an impeller measuring mechanism, a deceleration mechanism, and an indicator, and has a simple structure. Rotor-type water meters are suitable for measuring the total amount of water flow with small flow, so household water meters are generally rotor-type water meters.
Features of rotary wing water meter:
The rotation direction of the impeller of the rotary wing water meter is perpendicular to the direction of the water flow.
Rotor-type water meters can be divided into many types:
According to the counter can be divided into: C type, E type.
According to the applicable medium, it can be divided into tap water meter and direct drinking water meter.
According to the working principle, it can be divided into wet type, dry type, liquid seal, semi-liquid seal.
According to the installation method, it can be divided into horizontal, vertical, etc.
Water meter installation note:
If the water meter is used for a long time, impurities such as rust in the pipeline will block the filter screen or enter the water meter, which will increase the error of the water meter or affect the normal operation. It is best to clean it every three years and recalibrate it, but do not disassemble it yourself.
When the water meter is installed, there should be a free space of 400mm*40mm around the water meter and its related pipe fittings for maintenance and module replacement.
The diameter of the water meter should be selected according to the flow rate of the installation site, and corrosive liquids should not be used.
Spiral wing water meter: Spiral wing water meter is used to measure the total amount of water flow in large flow pipes. Wide working range, convenient installation and maintenance, small size and low sensitivity, especially suitable for water supply main pipeline and water consumption in large factories and mines. Its main features are large circulation capacity, small size, compact structure, and easy use and maintenance. Spiral wing water meters are often used to measure the total amount of water flow in high flow pipes. In general, large enterprises and schools will use screw-wing water meters.
