1 Description and Preparation
1.1 Description
The LEVIFLOW® LFS-SU flowsensors are
designed for non-invasive flow measurements in
single-use applications of the Life Science
industries. The wetted materials of the sensors are
made out of biocompatible polypropylene (FDA,
USP-VI, BSE/TSE and Animal free), which can be
gamma sterilized.
Figure 1: Single-use flowsensor (example LFS-06SU)
Before using the flowsensor make yourself familiar
with the following instructions.
1.2 Inspection Prior to Use
The flowsensor should be inspected prior to use for
any damage. Do not use the flowsensor if any
damage is found. Contact Levitronix®regarding
return of any suspected flowsensor.
1.3 Traceability for Troubleshooting
For full traceability of the flowsensor the serial
number located on the sensor body (see Figure 1)
shall be used. The serial number is also printed on
the biocompatibility declaration and the calibration
sheet delivered with each sensor.
1.4 Levitronix®Configuration Software
For sensor parameter setting and calibration
parameter transfer to the converter (not necessary
for sensors with a parameter chip) the Levitronix®
Configuration Software with version V1.30 or
newer is needed. For details regarding installation
of software and establishing RS485 connection
consult the LEVIFLOW®Configuration Software
manual (see Doc# PL-4501-00).
2 General Warnings and Cautions
CAUTION
Gamma Sterilization
The LFS-SU flowsensors
have been tested to be
robust against gamma radiation with a dose up to
40 kGy.
Handle the flowsensors
with care, especially after
gamma radiation with doses above 25 kGy, since the
radiation exposure decreases the flexibility of the
flowsensor material.
3 Procedure for Installation
3.1 Mechanical/Electrical Installation
Connect the sensor to the converter together with
the relevant adaptor cables. Take specific care
about the flow direction indicated with the arrow on
the flow sensor (see Figure 1). For details about
mechanical and electrical installation and design of
an adequate hydraulic circuit, consult the user
manual (Doc# PL-4509-00).
3.2 Setting of Sensor Type Parameters
The sensor type (or size) specific parameters can
be set or updated on the converter at the first
installation or whenever the sensor type is
changed.
Note: Sensors which are labeled with “Type: PC”
on the calibration tag have an integrated
parameter chip and parameters are transferred
automatically to the converter.
Start the LEVIFLOW®Configuration Software and
open the “Parameter Settings” menu (Figure 2).
Make sure that “Sensor Size”, “Full Scale”, “Kinem.
Viscosity”and “Liquid Temperature“ are set to the
values designated for the used sensor type.
Table 1table shows the standard values. For other
configuration consult the specific sensor
specification.

3.3 Transfer of Basic Calibration Values
Next step is to transfer the calibration values.
These values are available on the sensor tag or on
the calibration sheet delivered with each sensor.
Open the menu “Basic Calibration” of the
configuration software (see Figure 3). Update the
“K Factor” and the 5 “Calibration Values”.
Store the settings to the converter by using the
“Write to Converter” button.

3.4 Transfer of Linearizer Values
In some cases (for example for the LFS-03SU)
additional linearizer values are defined to increase
accuracy. These values are available on the
backside of calibration parameter tag or on the
calibration sheet delivered with each sensor. Open
the “Linearizer” menu (see Figure 4) of the
configuration software and transfer the linearizer
values.
Figure 4: “Linearizer” menu of configuration software
(Settings for example with LFS-03SU)
If no linearizer values are defined on the backside
of the calibration parameter tag (for example for
LFS-06SU and LFS-20SU), write “0” linearizer
points to the “Linearizer Points” item (see
Figure 5).
