Structure of
Inside measuring “head” of sensor
(1)
: electronic measuring unit, BLE module for wireless
and built-in battery (see figure 6).
Measuring part
(2)
of the sensor composed of two coaxial tubes that form condensate coating.
Changes of sensor electrical capacity depend on the diving depth of measuring probe into fuel
(dielectric liquid according to its properties).
WARNING:
Capacitive principle ensures highest accuracy of liquid measurement
when the liquid has
constant dielectric permeability coefficient
. Otherwise,
additional inaccuracy of measurement may appear.
