The FLOW UNIT range provides a solution for measuring and/
or controlling flow- rates for any fluidic applications. Combining
the FLOW UNIT with our pressure handling system (Flow EZ
TM
or
Flowboard combined with MFCS
TM
) will give you the opportu-
nity to check at all times flow-rate and volume of liquids flowing
through your fluidic system. The four different FLOW UNIT models
offer an extensive choice of flow-rate ranges to best match your
required precision, f rom 8 nL/min to 40 mL/min. Beside water
based solutions, a second calibration for hydrocarbons is available
on three (3) different FLOW UNIT models (S, M+ and L+), see §8.

General information
The Flow Unit enables flow-rate measurements, in a wide range of
flow-rates thanks to the five (5) models: XS, S, M+, L+.
The flow-rate acquisition is based on a thermal technology. A heating
element on the microchip adds a minimal amount of heat to the
medium for the thermal flow measurement. Two temperature sensors,
symmetrically located above and below the source of the heat, detect
even the slightest temperature differences, thus providing the basic
information about the spread of the heat, which itself is directly related
to the flow- rate.
