Nguyên lý hoạt động của cảm biến mức Finetek SP200, SP201, SP202, SP220,..

Thermal dispersion flow switches measure the
velocity of a liquid inside a pipe or channel.
The switch’s probe contains two key components
– a heating sensor and temperature sensor. The
heating sensor is positioned closest to the flowing
liquid and provides a consistent heat. The
temperature sensor measures the temperature
emitted from the heating sensor.
When liquid is flowing, there is a temperature
difference between the two sensors. The
temperature difference has an inverse relationship
with the flow velocity (fast flowing liquids will result
in greater heat differences and vice versa).
Since the device contains no moving parts, has no
wear and tear and maintains a long lifespan.

1. Use the water-proof gasket provided
2. The distance "a" should be 4 times larger
than the switches’ screw diameter. (Fig. 1)
3. The pipe is bubble free for proper
functioning. (Fig. 2)
4. For not-completely-filled pipes, install from
the bottom. The liquid level needs to be
higher than the probe height. (Fig. 3

4. Screw tightly to avoid. Can be installed
from various angles. For best sensitivity
and response speed, please install using in
the demonstrated in Fig. 4
5. Installing a filter upstream can decrease
liquid impurities which can reduce wear
and tear on the switch.
