Technical Information
Liquiphant M
FTL51C
Vibronic
Point level switch for all kinds of liquids
with high corrosion-resistant coating
Application
The Liquiphant M is a point level switch for use in all liquids.
– for temperatures of –50 °C to 150 °C (-58 to 302 °F)
– for pressure up to 40 bar (580 psi)
– for viscosities up to 10000 mm
/s (cSt)
– for densities of 0.5 g/cm
(SGU) or 0.7 g/cm
(SGU)
The device functions reliably regardless of flow, turbulence, bubbles, foam, vibration,
solids content or buildup, making the Liquiphant an ideal substitute for float switches.
All the wetted parts of the sensor (process connection, extension pipe and tuning fork)
are coated in enamel or various synthetic materials, making the point level switch
suitable for applications in very aggressive liquids.
International approvals certify use in hazardous areas.
