Note: Check that the self-adhesive protective film on both ends of the flow sensor is removed before installation.
7.1.2.2
Insulation
ULTRAFLOW® 54/34 should neither be insulated nor enclosed as natural ventilation of the sensor is thereby prevented.
Condensation, which is formed around the cooling sensor ULTRAFLOW® 34 when operating in hot, humid environments,
is thus entrapped. Should you after careful consideration decide to insulate ULTRAFLOW® after all, the electronics case
must at least remain uninsulated.
7.1.3
Maintenance and service during operation
The flow sensor is verified separately and can, therefore, be separated from the calculator. See the sealing drawings of
the connected calculator such as MULTICAL® 603 (5512-2029_GB) or MULTICAL® 803 (5512-2360_GB).
Due to the sealing levels of Pulse Transmitter/Pulse Divider (see
), it is also permitted to replace the supply and
exchange the supply type in Pulse Transmitter/Pulse Divider while ULTRAFLOW® is installed in the installation. For battery
supply of Pulse Transmitter/Pulse Divider, a lithium battery with connector from Kamstrup A/S must be used. Lithium
batteries must be correctly handled and disposed of (see Kamstrup document 5510-
408, ”Lithium batteries
- Handling
and disposal”). It is
also permissible to replace output modules of Pulse Transmitter/Pulse Divider.
The cable length between ULTRAFLOW® and the MULTICAL® calculator may be extended under certain installation
conditions, for example by use of Cable Extender Box, up to max 30 m (see
Other repairs of ULTRAFLOW® and Pulse transmitter/Pulse Divider require subsequent reverification on accredited
laboratory.
