A Small-Sized And Highly Sensitive Rotor Water Meter
A rotor water meter is a type of velocity water meter. Its working principle is that the water flow drives the rotor (rotor blade) inside the meter case to rotate. The rotational speed is directly proportional to the water flow speed. The number of rotations is accumulated through a gear transmission mechanism and converted into water consumption, which is displayed on the counter.
In simple terms: The faster the water flow, the faster the rotor rotates; the more rotations, the greater the accumulated water consumption.
When comparing the rotary water meter with the "one-meter-multiple-card water control machine" used in campus bathrooms, the clear differences in their positioning can be seen:
| Feature | Rotor water meter | Campus bathroom water control machine |
|---|---|---|
| Core Function | Pure measurement tool, only responsible for measuring and displaying the total water consumption. | Integrated system terminal for measurement, control, charging, and management. |
| Flow Control | No. The water flow is always unobstructed and cannot be actively shut off. | Yes. The water flow is switched on and off according to instructions through an electromagnetic valve/electric valve. |
| Charging Method | Not involved in charging, only provides measurement data. | Real-time charging and deduction, supports charging by time/flow. |
| User Identification | None. Cannot distinguish who is using it. | Yes. Different users are identified through a card reader. |
| Data Output | Mechanical reading, manual meter reading is required. | Electronic data, can be transmitted in real time to the management platform remotely. |
| Purpose | Trade settlement (water supply companies charge users). | Resource management and behavior control (schools save costs, students consume fairly). |
Rotary water meters are the fundamental components for water resource measurement and the "workhorses" that ensure reliable and economical water usage metering for thousands of households. However, in specific scenarios where precise control, resource conservation, and fee management are required (such as campus bathrooms), they evolve into a part of more sophisticated intelligent water control systems, exerting greater management efficiency. Although they share the same technical principle (both may use rotary metering units), they are completely different in terms of functionality and system hierarchy.
