Thermal insulation
Due to a low thermal capacity of the medium, the medium temperature can be greatly
affected by the ambient temperature through the supply line and the measuring device. The
influence of the ambient temperature on the medium temperature can be reduced by
insulating the supply line.
Vibrations
Due to the high operating frequency of the micro-channel, vibrations (<20 kHz) do not affect
measuring accuracy.

Special mounting instructions
Wall mounting
‣
Use drill holes and M6 screws to secure the filter to a wall or a secure base.

Pipe mounting
‣
Use the "pipe mounting kit" accessory to secure to a pipe or post.
Installation in a bypass line
Note the following when installing in a bypass line:
• A pressure drop must be created for the medium to flow through the measuring device.
• The maximum permissible pressure drop of 0.1 bar (1.45 psi) across the measuring device
may not be exceeded.
• The bypass line can be routed to the atmosphere or back to the process pipe.
Examples:
• Create necessary pressure drop with throttle (or flow monitor) downstream from the
measuring device.
