WBI Flow Sensors for HVAC and Analytical Instruments

The WBI sensors from First Sensor comes with I²C bus interface and offer mass flow measurement for gases and air based on an extremely sensitive thermal measuring principle. The WBI series includes unidirectional and bidirectional flow ranges. The digital sensors realize a very high accuracy over the whole measuring range in both positive and negative flow directions and feature low power consumption and rapid response times.

Common applications include HVAC, medical devices, instrumentation, as well as analytical instruments.
