Flow Sensors are devices used to measure the flow rate of the fluid either directly or indirectly. The Flow Sensor Market has been segmented based on the type of parameter the sensors measure, the technology utilized in the flow sensor and the end use application of the flow sensor along with geographic analysis. Flow Sensors can be classified by the fluid parameter which they measure such as: Differential Pressure, Positive Displacement, and Mass, Open channel and Velocity flow sensors and so on. Flow Sensors are classified based on the type of technology into electromagnetic, ultrasonic, orifice plate, carioles, open channel and pitot tubes and others. Flow Sensors are used in various industries including oil and gas, chemical, pharmaceutical, food and beverage as well as consumer applications such as HVAC. The market revenue of Flow Sensors is estimated to reach $8.49 billion exhibiting a growth of 7.1% through 2020.
