Liquiphant FTL51 - Vibronic Point level detection

Liquiphant FTL51 is a point level switch with extension tube for use in hazardous areas with all international certificates. 
Useable in all industries. FTL51offers functional safety SIL2/SIL3. With the second line of defense highest degree of
safety and availability of the device can be guaranteed. Reliable measurement values, not affected by: changing media
properties, flow, turbulences, gas bubbles, foam, vibrations or build-up.
