such as flash heater, central heating boiler and heater.
It should be assembled vertically.
It should be used in allowed using medium and application areas!
It is not used in the corrosive mediums, ambient with explosive and flammable material.
Conformity with medium to be measured should be also taken into consideration.

Palette, fastened from one point on the body, moves contact with fluid so that information about flow is obtained.
When flow stops, it is provided that paddle comes to first position by pushing magnet with reverse pole in the paddle,
attached on the body. By this means, longer life and resistance to higher pressure is provided in comparison with
those of spring mechanisms. Reed relay with high precision and long life is used.
