This manual contains information necessary for the safe and proper use of the LEVIFLOW®LFS flowmeter series.
Included are specifications for the standard configuration, components, and instructions regarding its use, installation,
operation, adjustment, inspection and maintenance. For special configuration of the LEVIFLOW®flowmeters refer to
accompanying information. If the flowmeters have to be configured for other parameter settings then the LEVIFLOW®
Configuration Software (see relevant manual Levitronix

Doc.# PL-4501-00) is necessary. Please familiarize yourself
with the contents of this manual to ensure the safe and effective use of this product. After reading, please store the
manual where the personnel responsible for operating can readily refer to it at any time.

1 Safety Precautions
CAUTION
Do not under any circumstances open the flowmeter housing.
Levitronix does not assume responsibility for any damage, which
occurs under such circumstances.
!
WARNING
Hazardous voltage may be present.
In case of the usage of an inadequate AC/DC power supply, mains
voltages may be present (even if the system is designed for 24VDC).
Do not under any circumstances open the powered converter.
The usage of galvanic separated 3rd party tested (like CE and/or UL)
AC/DC supply is highly recommended.
!
WARNING
Toxic chemicals may be present.
When using the flowmeter to measure chemicals skin contact and toxic
gases may be hazardous to your health. Wear safety gloves and other
appropriate safety equipment.

1. Remove the DC power from the flowmeter.
2. Remove the cable from the flowmeter connector.
3. Attach the necessary cable wires according to the pin specifications in Table 5.
4. For usage of a fuse at the power input (24 VDC) a 200 mA slow-blow type is recommended. Consider inrush
current specification (see Table 2), when choosing the fuse type and the AC/DC power supply.
5. Attach the cable to the flowmeter connector.
6. Before powering on check again all wiring connections. Confirm that the terminals are securely fastened and
that there is no possibility of short circuit.
3.1.3 Configuration of Flowmeter Data
The flowmeter comes configured with the sensor specific data already stored in it. A calibration sheet
including the calibration data (the K-Factor and the 5 Calibration Values) is also part of the package. In case
this data should have to be changed to the users specific needs LEVIFLOW®Configuration Software can be
used. Consult the configuration “Configuration-SW User Manual” (Levitronix

Doc.# PL-4501-00) for
handling with the LEVIFLOW®configuration software.
Note: The LFIF-06 flowmeter needs configuration software version V1.34 or higher.
3.2 Mechanical and Hydraulic Installation
3.2.1 Instructions
1. In order to mechanically fix the sensor body 4 threads (see Figure 2) can be used.
2. Assure that at the mounting location the allowed ambient temperature is not exceeded (see Table 2)
3. The flow circuit should be completely filled with fluid. The converter DSP (Digital Signal Processor) contains
special algorithms, which increase the robustness of the measurement against bubbles. However, assure
that excessive bubbles are avoided in the circuit.
4. Ideal mounting position for the flow sensor is upward flow direction to avoid the stagnation of bubbles and
particles in the measuring tube.
5. Make sure that the arrow mark on the flowmeter shows into the direction of the flow in the hydraulic circuit.
6. Avoid excessive vibrations such as in the neighborhood of displacement pumps. Insufficient contact of the
transducer (within the sensor) onto the pipe wall caused by vibration may result in inaccurate measurement.
7. The flowmeter measures flow velocity. In order to obtain fully developed flow pattern for accurate velocity
measurement, straight run of 60 mm upstream and of 40 mm downstream is recommended. If non-uniform
turbulent flow or swirl flow is expected, install longer upstream straight run and/or a flow-rectifier.
8. To install on pipe that has open end, the sensor should be mounted in lower position of the pipe line.
9. The flowmeter should be mounted where pressure in the pipe is above the atmospheric pressure.
10.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.
11.A bypass pipe run (including bypass valve and shutoff valve) is recommended for easy zero adjustment and
maintenance.
12.Please confirm that the maximum pressure is below the in Table 2 specified pressure of the sensor.
13.After setup a “Zeroing” is recommended. Assure that the sensor is completely filled 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. Then push the “ZERO”
button on the flowmeter for about 3 seconds. During adjustment the “High” and “LOW” LEDs are blinking.
14.In the following cases a re-zero is recommended:
a. 30 minutes after power-on of a cool converter and sensor
b. Change of fluid properties (temperature, viscosity, density)
c. Change of chemistry
d. Change of the hydraulic circuit

4 Operation
4.1 General Timing Specifications
4.1.1 Startup Time
After power-on a startup sequence proceeded. During this sequence flow measurement is not performed.
Start-up time is about 3 seconds.
4.1.2 Thermal Stability Time
To guarantee specified accuracy thermal stability of sensor has to be reached. Therefore it is recommended
to wait 30 minutes after power-on.
4.1.3 Zero Adjustment Activation Time
There are two possibilities to activate zero adjustment:
1. Activating by LEVIFLOW®configuration software: Zero adjustment starts immediately after pressing
corresponding button.
2. Activating by “Zero” button on the flowmeter (see Figure 4) has to be pressed during more than 3 seconds to
initiate zero adjustment.
4.1.4 Automatic Zero Adjustment Duration
The duration to perform an automatic zero adjustment is about 20 seconds.
4.2 Operation
4.2.1 System Operation with PLC Interface
Figure 5 shows the standard configuration of the digital and analogue output. For other configurations the
LEVIFLOW®configuration software has to be used (according manual is Levitronix

Doc.# PL-4501-00).
Note: The LFIF-06 flowmeter needs configuration software version V1.34 or higher.
4.2.2 Operation with RS485
Operation with communication over an RS485 bus is possible. The according MODBUS protocol can be
requested at Levitronix

4.2.2 Operation with LEVIFLOW®Configuration Software
For debugging, data collection and configuration of the flowmeter system the LEVIFLOW®Configuration
Software is available at Levitronix®. Contact Levitronix®for a sample of the configuration software and the
according manual (Levitronix

Doc.# PL-4501-00). An approved USB to RS485 adaptor with the according
connection cable can be ordered according to the information in Table 1.
Note: The LFIF-06 flowmeter needs configuration software version V1.34 or higher.
Figure 7: System operation with LEVIFLOW®configuration software
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 flow sensor body for example caused by
bended piping.
2. Inspect for loosen connections caused by excessive pipe vibrations.
3. Inspect the sensor visually for any deposits, excessive bubbles or foreign materials in the
measuring tube.
