Liquiphant M FTL50(H), FTL51(H)

Liquiphant M FTL50(H), FTL51(H)
Technical Information
Liquiphant M FTL50(H), FTL51(H)
Vibronic
Point level switch for all kinds of liquids
The reliable function is not affected by flow, turbulence,
bubbles, foam, vibration, solids content or buildup. The
Liquiphant is thus the ideal substitute for float switches.
FTL50:
Compact design, ideal for mounting in pipes and for
installation in areas difficult to access
FTL51:
With extension pipe up to 3 m (6 m on request)
FTL50H, FTL51H:
With polished tuning fork and easy-to-clean process
connections and housings for food and pharmaceutical
applications.
High corrosion-resistant: AlloyC22 (2.4602) is available
for the fork and process connections for applications in
very aggressive liquids.
International approvals certify use in hazardous areas.
Your benefits

• Use in safety systems requiring functional safety to
SIL2/SIL3 in accordance with IEC
61508/IEC 61511-1
• Design in accordance with ASME B31.3
• Suitable for use in sterile applications in the life science
industry (device design according to ASME BPE-2007)
• PROFIBUS PA protocol: for commissioning and
maintenance
• No adjustment: quick, low-cost startup
• No mechanically moving parts: no maintenance, no
wear, long operating life
• Monitoring of fork for damage: guaranteed function
• FDA-approved material (PFA Edlon)
• Compact stainless steel housing (optional): the IP69K
protection rating guarantees the unit remains
permanently tight and can keep out water even in the
event of intensive cleaning or flooding for several
hours.

Application
Point level detection
Maximum or minimum detection in tanks or pipes containing all kinds of liquids, including use in hazardous
areas, food and pharmaceuticals.
L00-FTL5xxxx-11-05-xx-xx-000
Function and system design
Measuring principle
The sensor's fork vibrates at its intrinsic frequency.
This frequency is reduced when covered with liquid. This change in frequency causes the point level switch to
switch.

Check the following:
• The residual current in blocked state
(up to 3.8 mA)
• That for low voltage
– the voltage drop across the load is such that the
minimum terminal voltage at the electronic insert
(19 V) when blocked is not undershot.
– the voltage drop across the electronics when
switched through is observed (up to 12 V)
• That a relay cannot de-energize with holding power
below 3.8 mA.
If this is the case, a resistor should be
connected parallel to the relay. An RC module is
available under the part number: 71107226
• When selecting the relay, pay attention to the

The check is activated and monitored at the switching unit.
The twin-core connecting cable (instrument cable) with a cable resistance of max. 25 Ω per core is connected
to the screw terminals (conductor cross-sections 0.5 to 2.5 mm) in the connection compartment. Protective
circuits against reverse polarity, HF influences and overvoltage peaks are installed.
Maximum line length up to 1000 m.
A shielded connecting cable is recommended in the event of strong electromagnetic interference. Here the
shielding must be connected to the sensor and the power supply.

Adjustment
In the Liquiphant M modular system, the option of an adjustment is also provided in addition to the electronics
(see feature 60: "Accessories").
There are three types of adjustment:
Standard adjustment (see ordering information for additional option, basic version A)
• Here, two fork parameters are determined to describe the sensor characteristics, indicated in the adjustment
report and provided with the product.
These parameters must be transmitted to the Density Computer FML621.
Special adjustment (see ordering information for additional option, special adjustment, density H2O (K) or
special adjustment, density H2O with 3.1 certificate (L))
• Here, three fork parameters are determined to describe the sensor characteristics, indicated in the
adjustment report and provided with the product.
These parameters must be transmitted to the Density Computer FML621.
Greater accuracy is achieved with this type of adjustment (see also "Performance characteristics").
Field Adjustment
• During field adjustment, a density value actually determined by the customer is entered and the system is
automatically adjusted to this value (wet adjustment).

• External equipotential bonding connection on housing: cross-section max. 4 mm2
Safety mode
Minimum/maximum residual current safety selectable on electronic insert.
(with FEL57 on Nivotester only)
Max. = maximum safety:
The output switches to the power fail response when the fork is covered
For use with overfill protection for example
Min. = minimum safety:
The output switches to the power fail response when the fork is exposed
For use with dry running protection for example
Switching time
When fork is covered:
approx. 0.5 s
When fork is exposed:
approx. 1.0 s
(Other switching times on request.)
Additionally configurable for PROFIBUS PA: 0.5 to 60 s
Switch-on behavior
When switching on the power supply, the output assumes the alarm signal.

Warning!
To avoid risk of contamination, install according to the "Hygienic Equipment Design Criteria (HDC)" as stated
in the Subgroup Design Principles of the EHEDG, Doc. 8, July 1993.
The flow of liquid during cleaning is important and should be in compliance with the HDC.
Note!
• For CIP (Clean in Place) and SIP (Sterilize in Place) processes the pressure and temperature specifications of
the process connections must be observed.
• Suitable fittings and seals must be used to ensure hygiene-compliant design according to 3A, EHEDG, ASME
BPE etc.
• Surfaces with ASME-BPE option: Ra < 0.38 μm (< 15 μin) electropolished and passivated or Ra < 1.5 μm
(59 μin) mechanically polished.
CRN approval
Versions with a CRN approval (Canadian Registration Number) are marked with a "*" in ordering information
feature 20 "process connection" (s. Seite 40 ff.). CRN-approved devices are fitted with a separate plate bearing
the registration number 0F10525.5C.
Process sealing according to
ANSI/ISA 12.27.01
Process connected Endress+Hauser instruments listed and marked “single seal” or “dual seal” according to
ANSI/ISA 12.27.01 do not require an additional means of gas-tight sealing in the installation. (Process Sealing
per NEC 501, 505, CEC Part I Sec.18 ).
