These immersion sensors are arranged horizontally and vertically at three heights. Why? Once again, physics is to blame, or more precisely, the convection of water. Liquids that are warmer than their surroundings rise, while colder liquids sink. To put it simply: if the reference liquid in the Sensorbottle warms up, the warmer liquid collects at the top; if it cools down, this is first measured at the bottom. For this reason, we measure the temperature at three different heights: Bottom, middle and top. Only in this way can the Sensorbottle react even faster and more accurately to temperature changes. In this case, three are better than one.
With regard to positioning, it does not matter how the Sensorbottle is positioned when it is upright. However, if the Sensorbottle is lying down, the display should be at an angle of 45° when viewed from above so that the sensors are vertically above each other.
