Wenglor weFlux² and UniFlow Calorimetric Flow Sensors
In Turkey, Mikron Proses supplies Wenglor weFlux² and UniFlow calorimetric flow sensors as the main seller and integrator of Wenglor fluid sensors. The calorimetric principle gives a measurement independent of flow direction and installation position, while the V4A 1.4404 (316L) stainless steel housing contains no moving parts.
weFlux² FXFF Compact Series
The weFlux² FXFF has a compact V4A 1.4404 (316L) stainless-steel housing with an integrated analysis module and is FDA compliant. It withstands 100 bar mechanical pressure and carries IP68/IP69K protection, for high-pressure process pipes and washdown. The sensor measures flow velocities from 10...400 cm/s and temperatures from -25...150 °C. Its switching output allows it to act as a flow switch for pump dry-run protection. Process connection options include G1/2" CIP-capable hygienic thread, 50.5 mm Tri-Clamp, and cutting-ring fittings. The FXFF is available with an IO-Link 1.1 interface, and variants with two 4...20 mA analog outputs (flow and temperature) are offered, such as FXFF101-104.
UniFlow FFAF / FFXF with 7-Segment Display
The UniFlow FFAF / FFXF series has a large 7-segment display that shows measured values as a percentage or in litres per minute, so the flow state can be read locally. FFAF001 covers 15...200 cm/s; FFAF002/003 and the FFXF series have a selectable measuring range of 10...300 cm/s. Mechanical resistance is 60 bar. FFAF is rated IP67 and FFXF IP67/IP69K. UniFlow sensors are set through an on-device menu and, depending on the model, offer one or two switching outputs, or one switching output with an analog output. The UniFlow series does not have an IO-Link interface; IO-Link is a weFlux² option.

Applications
- Pump dry-run protection: The switching output has a response time of 1...5 seconds to stop the pump when flow ceases.
- Cooling water and generator cooling lines: The weFlux² reads both flow velocity and temperature in the same sensor. For cooling system design, see the cooling tower automation guide.
- CIP cleaning cycles: The weFlux² is FDA compliant and EHEDG-certified in combination with selected process connectors; the UniFlow FFXF is FDA compliant and CIP-capable. For process details, refer to the CIP/SIP guide.
- Pharmaceutical and food filling: Flow velocity and temperature are tracked with a single sensor.
How Mikron Proses Helps
Mikron Proses selects the appropriate FXFF or FFAF / FFXF model based on pipe size, pressure rating, and hygiene class. The team helps specify G1/2" hygienic threads, 50.5 mm Tri-Clamp, or cutting-ring fittings, and integrates IO-Link 1.1 (weFlux²) or analog and switching outputs into the plant control system. For related online measurement, see the online analyzers range. For advice on choosing between sensor principles, see the flow sensor selection guide.

Frequently Asked Questions
Technical answers from Mikron Proses.
Where can I buy Wenglor weFlux² flow sensors in Turkey?
Mikron Proses supplies the Wenglor weFlux² FXFF and UniFlow FFAF / FFXF series in Turkey as the main seller and integrator of Wenglor fluid sensors. The sensors are used for cooling water monitoring, pump protection and CIP lines. For model selection, contact the team through the contact page.
What is a calorimetric flow switch and how does it work?
A calorimetric flow switch senses flow without moving parts. The weFlux² and UniFlow series use this principle to deliver a measurement independent of flow direction and installation position. When the flow velocity falls below the set threshold, the PNP/NPN switching output changes state to protect pumps or signal a cooling water interruption.
Can the weFlux² sensor be used for cooling water circuits?
Yes. The weFlux² FXFF covers flow velocities from 10...400 cm/s and temperatures from -25...150 °C, which suits cooling water and generator cooling lines. The 100 bar mechanical resistance and IP68/IP69K housing allow installation in demanding industrial environments.
Are Wenglor flow sensors suitable for CIP cleaning?
The weFlux² has a 1.4404 (316L) stainless steel body, is FDA compliant and is EHEDG-certified in combination with selected process connectors. The UniFlow FFXF is FDA compliant and CIP-capable. Process connections include G1/2" CIP-capable hygienic thread and 50.5 mm Tri-Clamp for direct integration into hygienic pipework.
What outputs do Wenglor weFlux² and UniFlow sensors provide?
The weFlux² offers switching and analog outputs, and an IO-Link 1.1 version; variants FXFF101-104 provide two 4...20 mA analog outputs for flow and temperature. UniFlow FFAF / FFXF sensors have a large 7-segment display and offer one or two switching outputs, or one switching output with an analog output, without IO-Link.
Does mounting angle affect measurement accuracy?
No. The calorimetric probe measures independently of flow direction and installation position, so the sensor does not need to be aligned with the flow.
