Battery-Powered Electromagnetic Flowmeter
Accurate, maintenance-free flow measurement in remote locations — no external power required
Approved by：CE, SIL-3, ATEX certification
The AFTLD battery-powered electromagnetic flowmeter uses internal battery power supply without external power supply. It is suitable for working conditions where the field power grid cannot be reached and the power grid is difficult to lay. It is especially suitable for the monitoring, measurement and settlement of the tap water supply system.
AFTLD battery-powered electromagnetic flowmeter converter, designed with ultra-low-power circuit technology, efficient and reliable excitation signal processing circuit, realizes measurement function, ensures high reliability and stability of converter, and adopts efficient system management Technology greatly reduces system power consumption, saving power costs while achieving accurate measurements.
Its intelligent sleep-wake algorithm and self-diagnostic firmware ensure consistent measurement accuracy without compromising battery efficiency.
- Independent Power System – Operates independently using a high-capacity lithium battery with low-power circuitry.
- Dual-Frequency Excitation – Maintains accuracy in low-conductivity or pulsating flows
- High Accuracy in the Field – ±0.5% accuracy maintained through dual-frequency excitation and digital signal processing.
- IP68 Protection – Fully waterproof enclosure for direct burial or chamber installations.
- Intelligent Data Logging – Internal memory stores up to 26,000 records for secure, traceable measurement.
- Low-Power DSP Circuitry – Optimized for energy efficiency and long battery life.
- Flexible Communication – Pulse, RS485, or optional GPRS for remote data transmission.
- No Moving Parts – Ensures zero pressure loss and eliminates mechanical wear.
- Real-Time Self-Diagnosis – Continuously monitors internal signals to detect abnormal flow readings, so you can identify issues before they impact accuracy.
