Turck Flow Sensor for Liquid Media

The Turck FCS-G1/2A4P-AP8X-H1141 is a compact calorimetric flow sensor designed to monitor liquid media in industrial environments. It integrates evaluation electronics directly into the stainless steel immersion probe with a G ½ process connection. This unit suits maintenance engineers and plant operators who need reliable flow verification without separate transmitter housings.

Installation Uses M12 Connector and Potentiometer

Installation connects via a standard M12 × 1 connector device operating on 19.2 … 28.8 VDC three-wire DC supply. The NO contact PNP output switches when flow exceeds the threshold set by the onboard potentiometer, while an LED band provides immediate visual confirmation. The plastic housing keeps weight to 438 g, though the fixed probe length limits positioning flexibility in tight pipework.

Calorimetric Principle Suits Clean Liquids Only

The calorimetric operating principle measures heat transfer from a heated element, so it requires liquids with consistent thermal properties and cannot detect flow in gases or slurries. The sensor is rated for standard application areas only and lacks specialised certifications for hazardous zones or aggressive chemical compatibility. Buyers needing bidirectional measurement or gas flow detection should consider alternative technologies.

Questions about this item

How can I verify the FCS-G1/2A4P-AP8X-H1141 flow sensor is operating correctly after installation?

The LED band on the sensor provides visual indication of flow status; a lit LED confirms the PNP output is active when flow is detected.

What comes in the box with the Turck 6870092 flow sensor and what must be purchased separately?

The box contains one flow sensor unit; an M12 connector cable for the DC 3-wire connection must be bought separately.

Which version of the FCS-G1/2A4P-AP8X-H1141 should I choose for my application?

This model is a single variant with G ½“ process connection, calorimetric principle, and 19.2 … 28.8 VDC supply; select it if those specifications match your requirements.
