FTL31 U3B Switch for Compact Liquid Monitoring

FTL31 U3B switch FTL31-AA4U3BAWSJ from Endress+Hauser is a configured Liquiphant FTL31 point level switch for liquids. It is used in tanks, pipes, and small vessels where reliable point level detection is required.

The FTL31 series uses vibronic technology and works without calibration. Therefore, it is suitable for overfill protection, pump dry-run protection, and general liquid monitoring. In addition, the switch can work reliably in applications with foam, turbulence, buildup, or changing liquid properties.
