Flow transmitter and switch for industrial liquids

Fluxicont FU4SK

Flow transmitter and switch for liquid flow and temperature, measuring 3…300 cm/s and –20 °C…+110 °C with RS485 Modbus®-RTU or IO-Link®, 4–20 mA and 2 push-pull switch outputs.

Introduction

Reliable flow monitoring matters when liquid processes need fast feedback and durable hardware. This compact transmitter and switch measures liquid flow and temperature continuously, with a calorimetric sensor covering 3…300 cm/s and process temperatures from –20 °C to +110 °C.
 
It fits a wide range of industrial tasks, including machine and plant engineering, climate and refrigeration systems, hydraulics and pneumatics, process industry, environmental technology and building automation. A broad choice of process connections, sensor lengths and electronics helps match the device to the installation instead of forcing the installation around the device.
 
Built for demanding environments, the fully welded stainless steel housing offers ingress protection (IP69K/IP67), pressure resistance up to 40 bar and tested shock and vibration resistance. RS485 Modbus®-RTU, IO-Link®, analog current output and two push-pull switching outputs support integration into modern control and monitoring systems.

Features

Calorimetric measurement

The device uses a wear-free calorimetric sensor for continuous flow and temperature monitoring in liquids.

Process connection options

Versions are available with G½"A or G¼"A process threads according to DIN EN ISO 1179-2 E.

Sensor length variants

Multiple sensor lengths support adaptation to different installation depths and process connection sizes.

Electronic output versions

Type V provides RS485 Modbus®-RTU. Type L provides IO-Link® with analog current output and two push-pull switching outputs.

Electrical connection

The device uses an M12 plug connection for the electrical interface.

Material configuration

Process-wetted materials include stainless steel 1.4404/316L, stainless steel 1.4571/316Ti, FPM and EPDM.

Optional configurations

Options include LABS-free and silicone-free execution, laser-marked TAG, EN10204 3.1 material certificate, drinking water suitability certificate and factory presetting.
