ALTOSONIC V
INTRODUCTION 1
1.3 System description
The ALTOSONIC V is a high precision instrument designed for linear, bi/directional flow
measurement of liquids. The ALTOSONIC V is partly positioned in a potential hazardous
environment and partly in a non-hazardous environment.
The Flow Sensor UFS-V and the Flow Converter UFC-V are designed and factory prepared to
function in a potential explosive environment. Housings and cable glands are certified types and
have to be handled in accordance with the specifications.
The remaining (optional) components of the ALTOSONIC V system, the Flow Processor UFP-V
and the supplied I/O rack configuration may only be operated in a safe non-hazardous area. The
I/O rack contains the additional I/O modules for a safe separation between hazardous and non-
hazardous environment. In this chapter the electrical connections between the different parts of
the installation are discussed.
Some additional material, that is not in the scope of supply, is required for connecting the PT100
in the Flow Sensor UFS-V to the Flow Computer UFP-V I/O-rack, the RS485 connection between
the Flow Converter UFC-V and the Flow Computer UFP-V I/O-rack and the power supply of the
Flow Converter UFC-V.
 Cables from the body temperature sensor Pt 100 of the UFS-V to the I/O temperature
module in I/O-rack 4 wire shielded twisted pairs
 The RS485 data connection between the Flow Converter UFC-V and the Flow Processor
UFP-V
