Afriso presents the USG 20 level limit switch, which is suitable for level detection and monitoring of tanks and pipes. The level switch works on the basis of ultrasonic technology. As the device has no interfering contours due to the flush mounting option, it is piggable in pipes, easy to clean in CIP/SIP systems and can even be used with small pipe cross-sections. The USG 20 is available with a wide range of process connections (e.g. G1/2, G3/4, G1, Tri-Clamp, milk pipe, Varivent, weld-in socket). This point level switch also enables non-invasive measurements from the outside through plastic containers or pipe walls.
