255 +There will be four cooling system sensor on the AR26 vehicle, and all of the sensors include two measurements each. These two signals are water temperature and pressure. With this the temperature delta over the entire cooling system can be measured, but also the overall water flow. If the equivalent orifice of the motors, inverters and other components are known, the flow can be calculated using the orifice equation.
