ALTOSONIC V
MECHANICAL INSTALLATION

are pre-wired. At one side cable glands are mounted. At each corner outside the housing there
are mounting brackets for mounting it e.g. on a suitable stable wall.
After mounting there shall enough space around the housing to open the cover and for the
cabling. It is allowed to mount the housing in each position, only avoid situations where
water will collect in the cable glands. Provide dripping bends on the cables.
After the electrical installation, carefully tighten the cover, all bolts shall be used.
Before closing the cover of the housing, inspect the flame path surface on mechanical
damage.
This surface shall be slightly greased to guaranty protection class IP65 and protection
against corrosion. The bolts for fastening the cover shall also be slightly greased also as
protection against corrosion. Greasing for instance with silicon grease.
Unused cable entrances shall be tightened with blind plugs.
Optionally the UFC-V is designed to operate within an ambient temperature of -40 …. +60°C
For use under -20 °C ambient temperature the housing is equipped with a heating device to
keep the electronics within its working temperature range.
If because of indirect heating e.g. by sunlight the housing temperature can become > +65 °C a
sunshade is recommended to prevent the electronics inside against excessive heating.

Ultrasonic Flow Processor UFP-V including I/O rack
The UFP-V Flow Processor has a standard 19" 6U high housing, PC-Based industrial
workstation with industrial grade high brightness DSTN LCD display. The workstation may be
mounted in a suitable 19” rack. This rack is standard not included. The dimensions of the
computer are 482x266x307 mm, mass is about 17 kg, maximum power 260W. Standard this flow
computer is equipped with CPU and several I/O boards. One of the boards is KROHNE specific.
For the cable connections, power I/O etc. an I/O rack is supplied, 19” 4U high. The certified unit
is containing all terminals for connection to mains and PE (protective earth), the terminals to
and/or from auxiliary equipment, I/O-modules and the interface card with the flow processor.
Dimensions: 482x176x250 mm, mass 5 kg, 19" 4U, maximum 20W.
Protection class for both items is about IP30. If a higher protection class is required, this can
only be attained using a cabinet with the desired IP classification. The cabinet can be equipped
with (mechanical) air circulation to prevent overheating the electronics.
