Klinger STG Thermal Massflowmeter DN50 PN40 SS304 0,7-700Nm3/h 4-20mA/RS485 24VDC Temp. -40…100°C. Klinger STG (DN15-DN2000 is a thermal mass flow meter,
based on the thermal dispersion principle,
which can be used for measurement on
pure dry gases.
Principle
The principle describes how a heated body
is cooled in a gas stream, and we hear it
mentioned daily on both TV and radio in
connection with the weather forecast. Here
we often talk about what the cooling of the
wind will mean for our perception of the
temperature - and how a strong wind can
give us the feeling that it is much colder than
it really is.
In practice, it is possible to use this
phenomenon to measure the flow. This is
done by controlling the heating of a body in
the flowing medium, the heating being
controlled so that there is always a constant
differential temperature with an identically
designed reference body. The power to be
used for the heating will then be proportional
to the mass flow of the medium.
STG is delivered in different versions, but
common to them all is that the two
temperature sensors (bodies) are located at
the tip of an insertion sensor, which must be
placed where the flow is desired to be
monitored.
This means that the sensor part itself will
only be a slight restriction in the pipe
system, and therefore it will be suitable for
working at very low operating pressures.
The main disadvantage of the measuring
principle is that it is a measurement at a
point, which means that the optimum
accuracy can only be achieved where the
speed profile of the product is defined. For
this type of meter - more than any other -
you need longer straight pipe lengths before
the meter, the longer the better for correct
measurement.
Application
Klinger STG can be used for most gases in
installations from DN10 up to DN 4,000mm -
in a very large measuring range - typically a
span of 100: 1.
A feature that makes the meter suitable for
tasks where both high flow monitoring and
leak detection are desired.
