Product Features of the Smart Prepaid Digital Water Meter with M1 Card:

Cutting-Edge M1 Card Technology: Our smart water meter employs cutting-edge non-contact M1 card technology, enabling wireless data transmission to tackle challenges such as waterproofing, moisture resistance, and anti-tampering measures.

Micro-Power Efficiency: With its micro-power technology, the meter typically consumes less than 0.5μA of power, dramatically extending the battery life to ensure reliable operation for over 6 years.

Electric Suspension Ball Valve Innovation: Our meter features electric suspension ball valve technology, characterized by anti-locking and non-fouling properties. This innovation minimizes pressure loss, wear and tear, power consumption, rusting, and blockages.

Automatic Valve Discharge and Anti-Rust Mechanism: The meter incorporates automatic valve timing that switches actions in response to the sudden pressure surges caused by water usage. This ensures automatic valve discharge to prevent valve rust, fouling, and related issues.

Comprehensive Seal Design: Every aspect of the meter is designed with a full seal using epoxy resin, ensuring impeccable sealing.

Protection Against External and Magnetic Attacks: In the event of external power or magnetic attacks, the meter will automatically close the valve, providing robust security against tampering.

Working Conditions:

Flow Range: Q1~Q3 (Q4 for short-term operation without changing error)

Ambient Temperature: 5°C to 55°C

Ambient Humidity: 0% to 93% RH

Water Temperature: For cold water meters: 1°C to 30°C, for hot water meters: 30°C to 90°C

Water Pressure: 0.03 MPa to1 MPa (short-term operation up to 1.6 MPa without leaks or damage)

Pressure Loss: ≤0.063 MPa

For accurate measurement, ensure a straight pipe length of 10 times the DN (diameter nominal) before the water meter and 5 times the DN after the water meter. The flow direction should align with the arrow on the meter body.

Power Supply Requirements:

The operating voltage for both alternating current (AC) and direct current (DC) should fall within -15% to +10% of the standard voltage. The frequency of AC should be within ±2% of the standard frequency.
