1 Introduction
The Prolevel FMC 661 field transmitter measures level with hydrostatic pressure sensors
or capacitance probes. It may be installed, commissioned and maintained by authorised
personnel only. The operating manual must have been read and understood before the
equipment is installed: instructions are to be followed exactly.
In this manualSince it is not possible to describe all applications in detail, the standard application,
continuous level measurement, has been used as the basis for the functional description.
Other applications as listed in Section 1.1 are described in Chapter 5. The operating
instructions are structured as follows:
•Chapter 1: Introduction;
contains general information including application, measurement
principle, functional description and technical data.
•Chapter 2: Installation;
contains hardware configuration, installation instructions and
connection diagrams.
•Chapter 3: Controls;
describes operation with the front panel keys, Commulog VU 260 Z,
and via the Rackbus RS-485 interface.
•Chapter 4: Calibration and Operation;
tells you how to commission the Prolevel for the standard
application including calibration, linearisation, analogue outputs,
relays and locking the parameter matrix.
•Chapter 5: Level Measurement with Limit Switch;
describes the automatic calibration correction and other operating
modes of the Prolevel FMC 661.
•Chapter 6: Trouble-Shooting;
contains a description of the self-checking system with error
messages, the simulation feature as well as instructions for
configuration on replacement of the transmitter, probe or
electronic insert.
•Appendix: Contains a flowchart for calibration and linearisation using
volume units.
•Index: lists key words to help you find information quickly.
Short instructionsShort instructions for the standard set-up, continuous level measurement, which is used
in 80% of applications, are to be found in the front cover. We advise you to commission
as described in Section 4.1. before using this procedure as this ensures that probes can
be exchanged without the need for re-calibration.
Further documentationIn addition to this manual, the following publications provide information on configuration
of the Prolevel FMC 661.
•BA 028F Commulog VU 260 Z handheld terminal
•BA 134F Rackbus RS-485
The installation of the probes, electronic inserts and accessories is described in the
documentation accompanying these articles - see text for references. When installing
probes in explosion hazardous areas the instructions included in the accompanying
probe certification must also be observed.

1.2 Measuring system
A working system for level measurement comprises:
•Prolevel FMC 661 transmitter,
•Capacitance probe or hydrostatic sensor for level measurement with
appropriate electronic insert, see Chapter 2
•If required, vibration sensor or capacitance probe for level limit detection or
automatic calibration correction.
The Prolevel may operate as a stand alone unit with standard 0/4…20 mA output; two
sets of two relays, freely assignable to channel 1 or 2, can be used to control pumps,
valves, annuciators etc.. Alternatively, the Prolevel may be operated remotely over the
optional Rackbus RS-485 interface, either direct from a personal computer or as part of
a process control system. Connection to Modbus, Profibus or FIP networks can be
realised through the gateways ZA 672, ZA 673 or ZA 674 respectively.
VersionsThe Prolevel is available in two versions:
•With display and front panel controls,
•Without display and front panel controls — in this case the transmitter must be
configured by the Commulog VU 260 Z handheld terminal or over the optional
Rackbus RS-485 interface.
In all other respects, the two versions are identical. More details on controls and operation
can be found in Chapter 3.

1.3 Measuring principle
The Prolevel FMC 661 measures level on the basis of the capacitance and hydrostatic
measurement principles. In both cases the measured value is processed by the
electronic insert and passed on as a frequency signal.
Capacitance
measurement The probe and vessel form the two plates of a capacitor, the total capacitance of
which can then be calculated from the
formula:
2πε0εrx L pF (1)
Ctot = C1 + -------------
ln (D/d)
whereby
Ctot = total capacitance
C1= capacitance of feed through
ε0= dielectric constant of air (8.85)
εr= rel. dielectric constant of product
D= diameter of vessel
d= diameter of probe
L= length of probe immersed in
product in meters
Measurement in
conducting media If the product conducts, the capacitance is now determined by the thickness and
properties of the insulating material
surrounding the probe. Equation (1)
applies, whereby the variable D is now the
diameter of the probe with insulation. In this
case the capacitance varies by approx.
300 pF/m.
Measurement is independent of dielectric
constant and not affected by changes in
this variable.
Hydrostatic
measurement In an open vessel, the level is derived from the hydrostatic pressure exerted by a
column of liquid on a probe placed at its
foot. The pressure exerted is:
p1=ρx g x h (2)
whereby
p1= hydrostatic pressure
ρ= density of the liquid
g = acceleration due to gravity
h = height of the liquid column.
Assuming a constant density, the level of
the liquid can be calculated from the
pressure measured by the Deltapilot.

1.4 Functional description
Fig. 1.7 is a block diagram of the Prolevel FMC 661. The transmitter supplies the power
to the sensor. The capacitance or pressure measured by the sensor is converted into a
frequency signal by the electronic insert located in its head and transmitted to the Prolevel
over a two-core cable. The signal is then processed to provide six operating modes.
Signal processingBy calibrating at two levels, »empty« and »full«, the frequency signal is converted to a
level measurement in the units entered during calibration. In mode 5, the measured value
at channel 1 is then corrected. For non-linear volume/level relationships, volume can be
calculated from level via the vessel characteristic which describes the shape of the
vessel. The signal resulting from the calibration and linearisation provides a standard
0/4...20 mA output, proportional to level or volume. Any portion of the measuring range
can be taken to provide a scaled output. The two sets of two relays can be assigned to
either measuring channel to provide level control by switching pumps on and off.
All measured values and the complete configuration can be accessed via the optional
Rackbus RS-485 interface.
Fail-safe operationIf a fault condition is detected, e.g. a break in sensor - transmitter cable, the analogue
signal switches to -10 % or +110 % level or holds the last measured value. The alarm
relay de-energises and the red LED on the front panel lights. In addition, each set of
relays can be set to switch on or off as required.

2.1 Probes and sensors
Table 2.1 lists the sensors most frequently used with the Prolevel FMC 661 transmitter.
In addition to those listed, all probes which can be used with an EC 17 Z, EC 37 Z or
EC 47 Z electronic insert can be connected to the transmitter. Installation hints can be
taken from the appropriate Technical Information Sheet.
Sensor constantsDeltapilot S hydrostatic pressure sensors and EC 37 Z/47 Z inserts are supplied with the
sensor constants zero frequency »fo« and sensitivity »∆f« or »S«, see Fig. 2.2. For
Deltapilot S sensors the constants depend on the measuring range, see Table 2.2. Note
these constants and enter them into fields V3H5 and V3H6 during commissioning,
Section 4.1. This dispenses with the need for a recalibration of the transmitter on
replacement of the sensor or insert.

2.2 Prolevel FMC 661 installation
Location Where possible, find a shady, protected spot in which to mount the Prolevel transmitter:
•Nominal operating temperature: 0°C…+60°C
Use a protective hood or provide cooling if the ambient temperature exceeds +60°C. For
temperatures below -20°C insulate the instrument.
Mounting The Prolevel FMC 661, with IP 66 protective housing, can be mounted on a wall or post
outdoors or in the control room. Fig. 2.3 gives details for wall mounting.
Fig. 2.4 shows how the Prolevel can be
post-mounted with the all-weather cover.
The fastenings (nuts and bolts) for both
post mounting and all-weather cover are

2.3 Transmitter wiring
Warning!
•Make electrical connections with the power supply switched off!
•The PE terminal strip must be grounded externally (contact protection)!
•When wiring up probes and sensors in explosion hazardous areas, observe the
instructions on the certificate and other local regulations.
Terminal stripThe terminal strip for cable diameters up to 2.5 mm2is located in a separate connection
compartment. Fig. 2.5 shows the wiring diagram for the Prolevel FMC 661 (Terminal 3 is
reserved for the internal protective ground):
•Remove the plastic cover from the front of the connection compartment
•Press out the pre-stamped cable entries as required
bottom: 5 x Pg 16, 4 x Pg 13.5; rear: 4 x Pg 16.
PowerThe power requirements are printed on the nameplate at the right-hand side of the
nameplate, see also Section 1.5, "Technical Data".
•If the specifications on the nameplate do not correspond to those of your
power supply, do not connect up - you may damage the instrument!
•Connect the protective ground to the metallic terminal strip provided at the left
— this ensures safe isolation and contact protection.
•Current output, relay outputs, power connection and sensor input are all
electrically isolated from one another.
Analogue outputsOnly one non-floating device can be connected to the current output.
•There is no limit to the number of floating devices, other than that imposed by
considerations of the maximum load of 600 Ω.
RelaysFor the switching capacity of the relays see the technical data in Section 1.5.
•Relays 1a and 1b are normally assigned to channel 1
•Relays 2a and 2b are normally assigned to channel 2.
The assignment can be changed by software, see Section 4.4.

2.4 Sensor connection
Sensor cable Use commercial 2-core installation cable, max. line resistance 25 Ω/core, for the sensor/
transmitter cable — the Prolevel satisfies the quoted EMC standards with this cable.
Level probes and
sensors, channel 1 The Prolevel FMC 661 can be operated with a variety of sensor types, each requiring a different electronic insert. For Channel 1, continuous level measurement:
•EC 37 Z or EC 47 Z for capacitance and Multicap probes
EB 17 or EB 27 P for Deltapilots S
Level limit switch,
channel 2: The level limit switch may be a vibration probe — Liquiphant (liquids) or Soliphant (solids) — or a capacitance probe, with electronic insert
•EC 16 Z/EC 17 Z for Multicap probes
EC 17 Z for other capacitance probes
•EL 17 Z for Liquiphant probes
EM 17 Z for Soliphant probes
EC 37 Z and EC 47 Z The electronic inserts EC 37 Z and EC 47 Z have two measuring ranges which can be
selected by inserting a bridge between terminals 4 and 5 of the insert, see Fig 2.6. Full
instructions on selection of the insert are to be found in Publication E 07.80.06/1c.
•Note the zero frequency fo____ and sensitivity S_____on the insert for the
range you have selected.
EC 17 Z The EC 17 Z electronic insert can be used at Channel 2 with capacitance and Multicap
probes for limit level switching. The connection diagram is shown in Fig. 2.6. Technical
information is given in Publication E 11.84.04/1a.
EC 16 Z The EC 16 Z electronic insert is for use on channel 2 with the Multicap probes with active
build-up compensation. Wire it up as described in the Technical Information Sheet
TI 170F delivered with the insert.
