OPTIFLUX 4300

ELECTROMAGNETIC FLOW SENSOR

Application

OPTIFLUX 4300 is an electromagnetic flow meter designed for measuring the flow of hot and cold water. Its electromagnetic technology gives it many advantages : no moving parts (no mechanical wear), high measuring dynamics, low pressure drop, low start-up flow and insensitivity to suspended particles.
It can also be used for glycol water measurement (without MID approval).

Features

Measures all conductive liquids with conductivity > 20 µS/cm
MID class 2 approval (for thermal energy)
Heat transfer fluid : water
Full range from DN 25 mm to DN 300 mm
Compatible with pulse input computers
Temperature range from +0°C to +180°C in separate version
Approval temperature from +0 to +140°C in compact version
Analogue output by default
Other optional communication bus
