1. Every sensor comes delivered with a calibration sheet. Check if the S/N on the calibration sheet
corresponds to the S/N of the sensor (see Figure 8).
2. Please store the delivered calibration sheet or its data on a defined storage place in order to be
able to refer to it in case of problems.
3. Assure that the correct calibration set for the tubing and liquid temperature is chosen. The
flowmeters are calibrated for multiple tubing types and liquid temperatures. Please check the
default factory setting on the article label. To switch to another calibration set the Levitronix®
Service Software or the user panel LUI-B.1-02 can be used (see Section 4.2.2).

3.3 Instructions for Electrical Installation
1. Remove the DC power and all cables from the flowmeter before any installation work is done.
2. For operation with the user panel LUI-B.1 or with a PC attach the cables as shown in Figure 3 and
Figure 4.
3. For operation with the OEM cable ICS-2.2 or ICS-2.4, attach the necessary wires (AWG 14-26)
according to the pin specifications in Table 5. Strip the sheath approximately 3 mm from the wires
end. Insert core into the cable terminal to the end and tighten the screw. Confirm that the wires are
securely fixed by pulling it gently by hand.
4. Alternatively, the terminal of the ICS-2.2 or ICS-2.4 cable can be removed to assemble another
connector like wall-mountable circular connectors for cabinet mounting.
5. If another AC/DC power supply than the one offered by Levitronix®is used, than the specifications
in Table 5 shall be considered (voltage range, consumption current and start-up current).
6. For usage of a fuse at the power input a 200 mA slow-blow type is recommended considering the
inrush (start-up) current of the flowmeter (see Table 5).
7. Before powering on check again all wiring connections. Confirm that the terminals are securely
fastened and that there is no possibility of short circuit.
8. When applying power, the controller needs about 10 seconds for a start-up procedure to be ready.
In order to get stable temperature and signals for converter and sensor 30 minutes must be waited
after power-on.
9. After start-up a Zeroing is recommended. Assure that the sensor is filled completely with the
according fluid, free of bubbles and that zero flow is realized. Section 4.1.3 explains the zeroing
possibilities.
10. The Levitronix®Service Software can be used to debug and configure the flowmeter over the RS485.
For communication with RS485 the MODBUS protocol can be requested at Levitronix

3.4 Mechanical and Hydraulic Installation
1. In order to mechanically fix the flowmeter body, 2 fixation threads on the backside of the housing can
be used (see Figure 6).
2. Assure that at the mounting location, the allowed ambient temperature and humidity ranges are not
exceeded (see Table 3).
3. Clamp the sensor to the tubing according to the procedure described in Section 3.5. Use only tubing
material for the specified calibration (see calibration sheet).
4. The flow circuit should be filled completely with fluid. The integrated converter contains special
algorithms, which increase the robustness of the measurement against bubbles. However, assure
that excessive bubbles are avoided in the circuit.
5. Ideal mounting position for the flow sensor is vertical direction (if not possible a slight angle) with
upward flow direction to avoid the stagnation of bubbles and particles in the measuring path of the
tubing.
6. An arrow mark on the flow sensor (see Figure 7) indicates the flow direction. Make sure that the
arrow corresponds to the direction of the flow in the hydraulic circuit.
7. Avoid excessive vibrations such as in the vicinity of displacement pumps. Insufficient contact of the
transducer (within the sensor) onto the pipe wall caused by vibration may result in inaccurate
measurement.
8. The flowmeter measures flow velocity. In order to obtain fully developed flow pattern for accurate
velocity measurement, straight run of 30x tubing ID upstream and of 12x tubing ID downstream is
recommended. If non-uniform turbulent flow or swirl flow is expected, install longer upstream straight
run and/or a flow-rectifier.
9. To install on a tubing that has open end, the sensor should be mounted in lower position of the
pipeline.
10. The sensor should be mounted where pressure in the pipe is above the atmospheric pressure in
order to avoid bubble generation by cavitation effects.
11. Devices like valves are recommended to be installed downstream of the sensor in order to prevent
formation of bubbles in the liquid. An upstream valve may form bubbles reducing the intensity of the
ultrasound signal and interfering with measurement.
12. A bypass pipe run (including bypass valve and shutoff valve) may be used for easy zero adjustment
and maintenance.
13. Please confirm that the maximum pressure is below the maximum pressure of the flexible tubing and
the maximum pressure of the sensor specified in Table 3.
11. After setup a“Zeroing”is recommended. Assure that the sensor is filled completely with the according
fluid and is free of bubbles. Stable liquid properties should be assured by flushing the circuit with the
final liquid until temperature and viscosity becomes stable. After this, zero flow shall be realized.
Section 4.1.3 explains the zeroing possibilities.
14. If Re-Zeroing is regularly necessary, automation is possible over the digital input of the flowmeter.
For the configuration of the digital input the Levitronix®Service Software is needed. Consult the
manual of the service software for more detailed description.
15. In the following cases a re-zero is recommended:
a. 30 minutes after power-on of a cool flowmeter.
b. Change of fluid properties (temperature, viscosity, density).
c. Change of chemistry.
d. Clamp-on of the sensor to a new tubing.
e. Change of the hydraulic circuit.

3.5 Instructions for Tube Mounting
1. Attention:
The LFSC-iX flowmeters are calibrated for
multiple tubing types and liquid temperatures.
Please check the default factory setting on the
article label. To switch to another calibration set
the Levitronix® Service Software or the user
panel LUI-B.1-02 can be used (see user
manual).
2. For a proper and accurate flow measurement it
is very important that the ultrasonic beam is not
disturbed by particles, dust and air in the
measurement path, which would result in
reflections and lead to a wrong flow
measurement. Specifically, it must be assured
that in the clamp-area between tubing and
sensor no particle or dust is squeezed in during
the clamp-on process.
3. Therefore, check the cleanliness of the surface
area where the ultrasonic beam leaves the
sensor and if necessary clean it with alcohol.
CAUTION
Do not use aggressive cleaning agents, which could
attack the sensor surface and its parts. Alcohol has
been tested and approved as an adequate cleaning
agent.
4. Check the tubing surface area, which is clamped
into the sensor, for cleanliness and inertness.
Assure that no particle or dust is present. Clean
the tube with alcohol or an adequate cleaning
agent specified by the tubing manufacturer.
5. Properly align the tubing with the clamp area of
the sensor and avoid bending or squeezing the
clamp area.

6. Fit the clamp hinge into the according sensor
body grove and close the clamp.
CAUTION
Take care to not squeeze the fingers during the clamp-
on process.
CAUTION
Assure that the tube is not squeezed and not axially
stretched during the clamp-on process.
7. For a stable and repeatable measurement, it is
very important that the tube is properly clamped
into the square shape of the transducer area of
the sensor. Therefore, check that the sensor is
properly fitted into the square area and that the
tubing is not squeezed somewhere.
1. After starting measurements with the system
with liquid temperature different from ambient,
or if the liquid temperature changes during
operation, full signal stability is reached after
about 30 min.
Do not squeeze the tube
during the clamp-on
procedure!
A squeezed tube affects
flow measurement!

pumps, may influence the accuracy of the flow reading. Following converter settings (different from the default
parameters in Table 4) are recommended to improve the measurement accuracy under highly dynamic flow
conditions:
Parameter
Setting or Value
Note
Low Cutoff
0%
Avoid cutting-off low flow spikes (for example from
roller pumps).
Damping Time
0.2 –0.5 s (seconds)
Reduces the filter frequency and allows more
dynamic flow readings.
Table 6: Recommended parameter settings for measurements of highly dynamic flow profiles
The settings can be done with the LevitronixService Software (see relevant manual).
5 Inspection and Maintenance
The LEVIFLOW®ultrasonic flowmeters do not require special maintenance since there are no moving parts
that can be subjected to wear and tear. However, the following periodical checks are recommended to ensure
smooth and reliable operation:
1. Check for excessive mechanical stress onto the tubing clamped on the flowmeter body for example caused by
bended tubing.
2. Inspect for loosen connections caused by excessive vibrations.
3. Inspect the sensor visually for any deposits, excessive bubbles or foreign materials in the measuring tube.
4. When using the tubing multiple times it is recommended to change the clamp-area on the tubing in order to
account for creeping effects in the clamp-area.
