Sensor pinpoints leaks in water lines
Researchers at the Fraunhofer Institute for Silicon Technology (ISIT) (Itzehoe, Germany) and their colleagues at Sensordynamics have developed silicon-based water flow sensors that can detect leaks in municipal fresh-water pipeline systems at a low cost. Acque S.p.A, researchers are testing the new robes that utilize MEMS (Micro-Electro-Mechanical Systems) technology and draws on the same principles as mass air flow sensors that measure the air intake in car engines. There is a sensor chip in the central to the probe design that features two heating wires mounted on behind the other within a thin silicon membrane that is (almost equal or equal to) 2 micron thick. An electric current flows through the wires and heats then to a constant temperature of (almost equal or equal to) 50 degree C and when cold water flows over the sensor, it cools the front wire and energy from that wire warms the water over the rear wire and lessens the cooling effect to the rear wire.
