1 Safety instructions
1.1 Designated use
The Levelflex M FMP40 and FMP45 is a compact level transmitter for the continuous measurement
of the interface level in liquids, measuring prinziple: Guided Level Radar / TDR:
Time Domain Reflectometry.
1.2 Installation, commissioning and operation
The Levelflex M has been designed to operate safely in accordance with current technical, safety
and EU standards. If installed incorrectly or used for applications for which it is not intended,
however, it is possible that application-related dangers may arise, e.g. product overflow due to
incorrect installation or calibration. For this reason, the instrument must be installed, connected,
operated and maintained according to the instructions in this manual: personnel must be authorised
and suitably qualified. The manual must have been read and understood, and the instructions
followed. Modifications and repairs to the device are permissible only when they are expressly
approved in the manual.
1.3 Operational safety
Hazardous areas
Measuring systems for use in hazardous environments are accompanied by separate "Ex
documentation", which is an integral part of this Operating Manual. Strict compliance with the
installation instructions and ratings as stated in this supplementary documentation is mandatory.
• Ensure that all personnel are suitably qualified.
• Observe the specifications in the certificate as well as national and local regulations.

3.2 Incoming acceptance, transport, storage
3.2.1 Incoming acceptance
Check the packing and contents for any signs of damage.
Check the shipment, make sure nothing is missing and that the scope of supply matches your order.
3.2.2 Transport
"Caution!
Follow the safety instructions and transport conditions for instruments of more than
18 kg.
Do not lift the measuring instrument by its probe rod in order to transport it.
3.2.3 Storage
Pack the measuring instrument so that is protected against impacts for storage and transport. The
original packing material provides the optimum protection for this.
The permissible storage temperature is -40 °C…+80 °C.

3.4 Installation
3.4.1 General instructions for interface measurement
For the measurement of the interface level, the coaxial probe, the rod or rope probe may be used.
However, rope and rod probes may be used in bypass resp. stilling well only. Rope probes should be
used in exceptions only, e.g. if the measurement range extends for more than 4 meters or the
available space above the tank is too limited to introduce rod probes.
The following constraints for the Levelflex Interface Version have to be considered:
• The overall level has to be constant.
• The dielectric constant of the upper prodcut level has to be smaller than 10.
• The difference between the dielectric values of the two product levels should be 10 or bigger.
• The minimum product level of each product is 100mm.
!Note!
If one of these conditions is not met, the interface level measurement is not possible!
3.4.2 Installation
• Coaxial probes may be mounted directly into the tank.
• Rope and Rod probes have to be mounted into a bypass or stilling well
• For the use of any probes into stilling wells it has to be made sure that the stilling well or bypass
is perforated in a way which allows the product level in the inner part of the stilling well to adjust
to the outer level.
• The diameter of the stilling well / bypass should not exceed DN150 / 6” and not be smaller than
DN 50 / 2”
For a bypass, the dimensions of the following diagram should be kept:

FMP45: Installing with heat insulation
• If process temperatures are high (≥200 °C), FMP45 must be included in normal tank insulation
to prevent the electronics heating up as a result of heat radiation or convection.
• The insulation may not exceed beyond the points labelled "MAX" in the drawing.
