Capacitance level measurement

For continuous measurement in liquids

Application
The Liquicap M FMI5x compact transmitter is used for
the continuous level measurement of liquids.
Thanks to its robust and tried-and-tested construction,
the probe can be used both in
vacuums and in overpressure up to 100 bar. The
materials used allow operating temperatures in the
medium container of –80 °C to +200 °C.
Used in conjunction with Fieldgate (remote measured
value interrogation via the Internet), Liquicap M
provides an ideal solution for inventorying materials and
optimizing logistics (inventory control).
Your benefits
• No adjustment necessary for media with a
conductivity of 100 μS/cm and higher. The probes are
adjusted to the ordered probe length on leaving the
factory (0 % to 100 %). This makes easy and fast
commissioning possible.
• Menu-guided local configuration via plain text display
(optional)
• Universal application thanks to wide range of
certificates and approvals
• Use also in safety systems requiring functional safety to
SIL2 in accordance with
IEC 61508
• Corrosion-resistant, FDA-listed materials in contact
with the process
• Can be switched for media forming buildup
• Short reaction times
• No need for readjustment after replacing electronics
• Automatic monitoring of electronics and possible
damage to insulation, as well as rod breaking or rope
tearing
• Suitable for interface measurement

PFM output (FEI57C)
