## Resumen

Battery-powered insertion ultrasonic water meter for agricultural irrigation and water supervision, with IP68 protection and no pressure loss.

## Descripción

### Product Overview

The RBBW-I is a battery-powered insertion ultrasonic water meter for agricultural irrigation, garden management and water supervision. Insertion mounting keeps pressure loss at zero, and the ultrasonic principle has no rotating parts, so accuracy holds up in water carrying gravel and weeds.

A built-in volume controller and time accumulator enable automatic, scheduled and quantitative water supply, while time-sharing flow accumulation supports gradient and rate-based billing.
