Necessary direction and distribution of gas flow over the surface of the meter provides a well-defined internal geometry of the measuring chamber sensor. In the course of the heating element reaches a temperature of 160 0C higher than the ambient temperature. At zero gas flow over a surface measuring the output voltage of the bridge is zero. At the same time of the gas flow sensor is located along the first stream is cooled and the temperature sensor that is located on the opposite side, heated. As a result the unbalancing and the output voltage appears, the magnitude and sign of which are proportional to the volume and direction of gas flowing per unit time through the measuring chamber sensor.

Due to the small size of the sensing element, extremely low thermal mass and high temperature gradient flowmeters Honeywell characterized by very short response time (about 1 ms), high repeatability and low hysteresis. Because the sensors are proportional to the proportional measurement technique, the maximum accuracy is achieved near zero flows.
Due to the very low energy consumption of sensors Honeywell completely safe device. All these advantages plus the compact design make these devices suitable for many different applications. Currently, flow Honeywell has successfully used both in domestic as well as medical and industrial equipment. Main application areas are: hvac system, climate control systems, systems of distribution of oxygen in hospitals; alv apparatus, gas chromatographs; control gas leakage. Types of sensors, their characteristics and especially on the degree of integration of all sensors Honeywell gas flow can be divided into two groups.
