Two sensors are used to measure the variation in a particular physical property of the flowing fluid. The sensors are located along the pipe at a fixed distance. If both the sensors detect a similar variation in the physical property over a time interval T, then L/T is the velocity of the particular fluid. It should be noted that this technique measures the change (signal signature) and not ...

20190604· A gas sensor is a device which detects the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage. Based on this voltage value the type and concentration of the gas can be estimated. MQ6 Gas Sensor ...
