ALTOSONIC V
ELECTRICAL INSTALLATION

Construction
The Flow Processor UFP-V, is an industrial type computer, e.g. Advantec Workstation AWS-
842T. The I/O modules are mounted on the front side of the I/O-rack and transfer the
(intrinsically safe) process inputs to the flow processor. On the back side are the connections to
the UFC-V field mounted converter unit, the custody transfer certified pulse output, the Modbus
connection, as well as binary status outputs and control inputs. For custody transfer purposes
the panel may be sealed. The optional printer connection is direct on the terminal of the
workstation and is supplied with a DB9 connector. See figure for terminal side of the
workstation).
I/O rack input signals (front side)
The I/O modules are interfacing with process instruments for:
 Temperature, Pt100 or 4…20 mA transmitters;
 Pressure 4...20 mA transmitters
 Density transmitters with frequency superposed on the loop current.
Note: Modules may be intrinsically or non-intrinsically safe.
Custody transfer certified I/O modules that may be used are:
 Made by MTL (Cenelec, FM and CSA Ex i certified modules)
MTL 5073/4 Pt 100 temperature input
MTL 7206 4 .. 20 mA loop powered transmitters
MTL 7087 4 .. 20 mA loop powered density transmitters
 Made by Phoenix (for non Ex circuits)
MCR-T-UI Pt 100 temperature input
MCR-CPS-I/I-44-E 4 .. 20 mA loop powered transmitters
 Made by Pepperl & Fuchs
KFD2-CD-Ex1.32-8 4 .. 20 mA current output

Data sheets of the different modules are not included because it is dependent of the ordered
configuration. Connections are not renumbered so the data sheets of the modules and the
equipment connected are needed for the planning of the installation.
Connection of the body temperature sensor of the UFS-V to the I/O module
Because the flow sensor UFS-V is mounted in a potential hazardous are an Ex-i certified I/O
interfacing module MTL 5073/4 for the body temperature shall be used. The body temperature
sensor terminals are interfaced as follows:
MTL 5073/4 connection
