The RBXEF-B is a battery-powered electromagnetic water meter designed for irrigation districts, remote networks and locations without mains power. Four 3.6 V lithium cells deliver 3–6 years of operation, and the IP68 housing allows installation in flooded chambers.
Bi-directional measurement, a 200:1 (optional 500:1) turndown ratio and NB-IoT/GPRS reporting make it a practical choice for NRW management and agricultural irrigation billing.
The RBXEF-B offers Class 1 & 2 (±0.5% / ±0.2%) accuracy, verified through our ISO 9001-managed factory calibration process.
The RBXEF-B is available for pipe sizes from DN50 ~ DN500 (DN600 – DN1200 optional), supporting a wide range of industrial flows.
The RBXEF-B supports Pulse, RS485 Modbus, GPRS/NB-IoT, frequency 1–5000 Hz output for integration with your control system.
Open-channel electromagnetic flow meter using area-velocity measurement for reliable flow and level data in sewage, stormwater and irrigation channels.
Ultra-low-conductivity electromagnetic batching meter with stable zero and ±0.2% batching accuracy for pure and low-conductivity liquids down to 1 μS/cm.
Battery-powered electromagnetic flow converter with IP68 housing and 3–6 year lithium battery, compatible with major magmeter sensor brands for remote metering without mains power.
