GPRS Electromagnetic Water Meter
Product Overview
The electromagnetic water meter is an instrument designed to measure the volumetric flow of conductive liquids based on Faraday’s Law of Electromagnetic Induction. Equipped with robust Modbus RTU/RS-485 communication and multiple transmission methods (GPRS/3G/4G), it delivers rich data transmission capabilities, enabling real-time monitoring of key parameters such as instantaneous flow, cumulative flow, pipeline pressure, and battery status from meters located kilometers away. It features a wide measurement range, low starting flow rate, minimal pressure loss, high accuracy, and exceptional sensitivity. Primarily used for leak detection in large-user District Metering Areas (DMA), online monitoring, water loss analysis, and statistical billing. An optional pressure sensor allows simultaneous measurement of flow and pressure.
Performance Features:
· Direct-reading electromagnetic water meter with on-site display of instantaneous and cumulative flow.
· Battery-powered with replaceable design. High-definition LCD screen for intuitive measurement.
· Simple installation—bury underground or mount in wells. Maintenance-free and user-friendly.
· IP68 (NEMA 6P) protection rating. Full stainless steel housing and infrared remote control, suitable for long-term submersion.
· Microprocessor technology ensures fast computation, high precision, adjustable low-frequency rectangular wave excitation, and low power consumption.
· SMT component mounting ensures stable and reliable circuitry.
· Self-diagnostic and self-monitoring capabilities.
