Location

The flowmeter can be located both indoors and outdoors, but the following conditions must be
observed:
Liquid temperature
The FC300 DN 4 is available in 2 temperature versions:
Standard version:
High temperature version:
For the high temperature version the multiple plug is raised from the sensor housing by a pipe,
as the maximum temperature of the plug is 125 °C (257 °F). It is possible to insulate the sensor
while still having access to the plug.
Important.
When the liquid temperature and the ambient temperature differ too much, the sensor must be
insulated to prevent 2-phase flow causing possible loss of measuring accuracy. This applies
especially in applications with low flow.
The sensor must always be completely filled with a homogeneous liquid or gas in single phase,
otherwise measuring errors will occur.
