Wireless Multi-Jet Rotary Vane Water Meter Key Features
Customizable pulse output intervals: 1L, 10L, 100L configurable
Multi-sensor compatibility: Hall-effect, magnetoresistive (MR), or non-magnetic sensing options
Integrated modules: MCU, memory chip, communication module (NB-IoT/LoRa), and Bluetooth
Non-invasive maintenance: Counter removable without shutting off water flow
Universal installation: Compatible with standard water meter dimensions
Operating Conditions
Cold water: ≤30°C
Hot water: ≤90°C
Pressure: ≤1 MPa
Environmental: Must be installed in dry, accessible locations (waterproof enclosure optional)
Communication Protocol：NB-IoT / LoRaWAN
Maximum Allowable Error:
±5% in low flow zone (Q1 ≤ Q < Q2)
±2% in high flow zone (Q2 ≤ Q ≤ Q4)
