Multi-Jet Rotary Vane Wet Water Meter
The multi-jet wet-type water meter is a common type of water meter used for measuring water flow in residential, commercial, and industrial applications. It is designed with multiple water jets that strike the turbine blades, causing the rotor to spin. The rotation of the rotor is proportional to the flow rate, enabling accurate measurement of water consumption.
● Multi-jet Design: Water enters the meter through multiple jets, ensuring uniform distribution of flow and reducing turbulence. This design improves measurement accuracy, especially at low flow rates.
● Wet-type Mechanism: The measuring mechanism is in direct contact with the water, making it suitable for clean water applications. The wet-type design is simple, durable, and cost-effective.
● Vertical Turbine: The turbine (rotor) is mounted vertically, allowing for compact installation and efficient operation.
● High Accuracy: The multi-jet design and precise rotor movement ensure high measurement accuracy across a wide range of flow rates.
● Low Maintenance: The robust construction and simple design minimize the need for frequent maintenance.
● Maximum Permissible Error: Lower Flow Range (Q1 ≤ Q < Q2): ±5%, Upper Flow Range (Q2 ≤ Q < Q4): ±2%
