The case: Together with the middle cover, the crystal and the sealing gasket, it forms a sealed body to prevent the leakage of the measured water. The inner hole of the case is usually lined with a corrosion-resistant material or coated with a good anti-rust coating.
Screw wing: Generally, it is injection molded with engineering plastics (such as ABS). The cylinder is hollow to reduce weight and increase buoyancy. One end has a cover to prevent water from entering and increasing weight. It needs to have good dynamic balance performance; otherwise, the screw wing shaft and shaft sleeve are prone to wear during high-speed operation.
Error adjustment devices: Common types include paddle type error adjustment devices and rudder type error adjustment devices. By rotating the adjustment plate, the impact force of water flow on the rotation of the screw blades is increased or decreased, thereby achieving the effect of error adjustment.
Counting mechanism: It is used to record the number of rotations of the screw blades, thereby obtaining the water flow data. It is largely similar to the counting mechanism of the rotor water meter.

Rectifier: Its function is to transform turbulent water flow into laminar flow. The central shaft hole is used to support the rotor shaft, and this shaft hole must be coaxial with the shaft hole on the bracket to ensure the flexible rotation of the rotor.Screw wing: Generally, it is injection molded with engineering plastics (such as ABS).

Support frame: It is used to support the screw wing shaft, enabling the screw wing to rotate flexibly under the action of water flow. Meanwhile, through the worm gear inside the support frame meshing with the worm on the screw wing shaft, the rotational speed of the screw wing is transmitted to the upper part of the support frame and connected to the counting mechanism.Error adjustment devices: Common types include paddle type error adjustment devices and rudder type error adjustment devices.
