Clamp-on ultrasonic flow sensor

The Keyence FD-R50 is a clamp-on ultrasonic flow sensor designed for non-invasive measurement on 40A and 50A pipe sizes. It attaches to the outside of piping without cutting or process shutdown. The sensor uses ultrasonic transit-time technology to determine flow rate. This makes it suitable for monitoring liquids in existing industrial systems.

Suited for retrofit monitoring on 40A and 50A lines

Engineers needing flow data on installed 40A or 50A pipes without breaking containment will find this sensor fits the requirement. It is not intended for pipes outside the 40A and 50A range or for applications requiring an in-line wetted sensor. Buyers who need a different pipe diameter or an insertion-style meter should look at other models.

Pipe size compatibility 40A and 50A

The single specification that decides fit is the pipe size designation of 40A and 50A. The sensor clamps are machined for these two nominal diameters only. Confirm the exact pipe outer diameter matches the 40A or 50A standard before ordering. No other pipe sizes are supported by this model.

Questions about this item

What pipe sizes does the FD-R50 clamp-on ultrasonic flow sensor support?

The FD-R50 supports 40A and 50A pipe sizes, allowing non-invasive flow measurement on these diameters.

How is the FD-R50 mounted on the pipe?

The FD-R50 uses a clamp-on design that straps onto the exterior of the pipe without cutting or process shutdown.

What coupling step is critical when installing the FD-R50 sensor?

Applying sufficient ultrasonic coupling gel between the sensor face and pipe wall is critical; skipping this creates air gaps that block the signal.
