With the continuous development of technology, automation technology has been increasingly applied in various fields. Water meter no wire actuator, as one of the core components, are gradually becoming important equipment in the industry due to their high efficiency and convenience. As the name suggests, water meter no wire actuator combine wireless control and electric actuation functions.
These devices are usually driven by electric motors and perform actions based on control signals to achieve precise control. Compared with traditional wired actuators, the biggest advantage of water meter no wire actuator is that they support remote control via wireless networks, which eliminates the complexity of physical wiring and offers greater flexibility.
| Parameter Item | Standard Specification Value | Supplementary Notes (Compliance & Application) |
| Rated Operating Voltage | 3.6V DC | Standard voltage for smart water meter lithium batteries, universal for mainstream battery-powered models |
| Operating Voltage Range | 2.5V - 5V DC | Wide voltage compatibility, stable performance within the range; higher voltage boosts torque slightly but may shorten service life |
| No-load Operating Current | ≤ 25mA | Ultra-low standby power consumption, effectively extends the service life of built-in water meter batteries |
| Locked-rotor Current | Approx. 450mA (300-series motor) | Built-in overload protection, prevents motor burnout during valve jamming; 300 motor is a high-stability standard configuration |
| Output Torque | ≥1.8N·m (2400:1 reduction ratio); ≥2.7N·m (3700:1 reduction ratio) | High torque to resist municipal water pressure impact, ensuring stable valve opening and closing |
| Valve On/Off Actuation Time | ≤10s (2400:1 reduction ratio); ≤16s (3700:1 reduction ratio) | Fast response speed, meets real-time control requirements of smart water meter systems |
| Gear Reduction Ratio | 2400:1 (Applicable for DN15-DN20); 3700:1 (Applicable for DN25) | Precision reduction ratio matching, tailored for different standard water meter calibers |
| Waterproof Grade | IP67 | Fully dust-tight, resistant to temporary water immersion within 1m depth for 30 minutes; suitable for humid, water-exposed meter installation environments |
Standard pin sequence for plug-and-play connection; pin functions and sequence can be customized according to customer project requirements
| Pin Number (2.0mm) | Pin Function Definition |
| I | Valve Open Control Signal |
