## Overview

Magnetic flow converter and transmitter compatible with major magmeter sensor brands, offering PWM field excitation, full-digital processing and rich communication options.

## Description

### Product Overview

The RBEFC is a magnetic flow converter/transmitter designed to work with electromagnetic sensors from Krohne, ABB, E+H, Yokogawa and Rosemount. Programmable low-frequency square-wave field excitation and a 16-bit MCU deliver strong noise immunity and stable readings in demanding installations.

Compact and remote versions cover panel, pipe and wall mounting, making the RBEFC an ideal replacement or upgrade for existing converter installations.
