ABSTRACT:
A sensor component that may be used in conjunction with a filter module may include a plurality of sensor packages. The latter, in turn, may incorporate one or more micro-electromechanical systems (MEMS) sensors to measure various characteristics of fluid flow and filtration. A single sensor component may be adapted to measure the pressure, temperature, flow rate, differential pressure, conductivity, viscosity, pH level, etc. of the fluid at an upstream and a downstream location. Sensor measurements may be obtained continuously in order to monitor and indicate fluid conditions, including the use of a warning mechanism to indicate an out-of-range condition when the measurements fall outside of pre-set limits. Depending on the application and the fluid being filtered, data, including measurement data, may be transmitted through electrical connections or wirelessly. In wireless configurations, a sleep-mode may be included to maximize the life of local power supplies.
