Fluid temperature mixing indicator

Abstract From the Canadian patent

This invention relates to a system to provide a controlled temperature mixing of two or more fluids by an immediate visual indication of necessity for particular adjustment and achievement of a predetermined fluid blend temperature range. The device includes plumbing fixture apparatus comprising a pair of manually controlled hot and cold fluid mixing valves and an integral fluid flow activated temperature sensor with electronic translation of fluid temperature imbalances between sensed blended fluid temperature and predetermined temperature values. A fluid temperature imbalance will cause illumination of a particular fluid control valve handle thereby indicating that corrective temperature …
