Innovative Sensor Technology (IST) AG, Wattwil, Switzerland, offers the microflowSens mass flow sensor element with a <10 ms response time. The 2.23 by 3.5 mm chip has measuring resistors wired in a Wheatstone bridge to minimize the number of external electronic components devices. The resistors, lined up in a row, cause a temperature gradient when the surrounding media flows over it; signal strength correlates to mass flow and sign of the gradient reflects the direction of flow. The positioning holes let you position the device and mount the sensors to a PCB. Applications include medical flow measurements and differential pressure monitoring.
