US Patent 10551276 Vehicle coolant flow and coolant quality sensor assembly

A vehicle coolant flow and coolant quality sensor assembly for use in an internal combustion engine (ICE) vehicle, a hybrid vehicle, or an electric vehicle. The coolant flow sensor includes a dual coil magnetic flow meter or the like for measuring coolant flow rate and the coolant quality sensor includes a sealed hot wire anemometer or the like and an integrated temperature sensor or the like for measuring coolant quality (e.g., ability to absorb heat) and coolant temperature, respectively. The various sensors are disposed in an integrated housing through which coolant is transported.
