## Resumen

Battery-powered electromagnetic water meter for irrigation and remote water metering without external power, with IP68 protection and 3–6 year battery life.

## Descripción

### Product Overview

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.
