2.3.1.1 Standard Sender/Receiver Units
A special transducer design makes it possible to use these sender/receiver units without
cooling by extern purge-air even with higher gas temperatures. The advantages are:
• Lower expense for mounting and installation
• Easier maintenance
• Lower operating costs.
For these reasons, standard sender/receiver units should be used where possible.
The types FLSE100-M, H and PR are intended for use with gas temperatures up to max.
260°C. The types FLSE100-SA and SD are inteded for use up to 150 °C.
Note: The measuring system FLOWSIC100 S contains one sender/receiver unit FLSE100-SA and
one unit FLSE100-SD.
The type FLSE100-SA has no electronics unit. The communication to the FLSE100-SD as
master (which communicates with the MCU control unit) is carried out via an analog cable
(fixed length: 3m).
Note: In gases with dust concentrations > 1 g/m³, the sender/receiver units have to be installed
in an angle to the flow direction of 60° (applies only for FLSE100-H). The downstream send-
er/receiver unit (slave in Fig. 2.4) has to be equipped with a rebound protector.
In addition to the various versions, the following differences apply:
The type FLSE100-M is
available with other
flanges on request (see
Section 2.7.1).
