ANDERSON NEGELE
The Anderson-Negele FWS/FWA is a flow switch with an optional 4-20mA or frequency output (changeable on the sensor) to enable it to give not only a PNP switch point output but also a volumetric output when required (+/- 10% full scale accuracy on output). Using the ultrasonic Doppler principal for flow detection means that the FWS and FWA are completely independent of system temperature fluctuation, media conductivity and system pressure. There is also an LED to indicate the state of the switched output, which is freely scalable across the flow range of the sensor.
This product is ideal for dry pump running detection due to its fast reaction time, use in CIP/SIP systems with a high temperature version available as well, if required. The sensor is designed to operate at 140°C for 120 minutes continuously without issue and all media contacting materials are FDA compatible. An ideal lower cost FDA approved sensor where using a more expensive technology isn’t necessary and switching or “rough” flow volumes are all that is required.

A few pictures from our recent team day (& night!) in Dublin City. A great day where we welcomed some of the OEM Sweden team also.
We recently had an incredible team building day at Croke Park where we had inspirational talks from Mark Donovan and also Niall Breslin, who talked about the excellent work his charity A Lust For Life.
Our partners and friends from OEM Automatic AB Sweden attended also. Great to show them a piece of Irish history.
Thanks to all involved and also to our amazing team for their hard work and dedication 💪
