Abstract
Measurement of flow rate is an essential requirement of process Industry. There
are many methods which are employed for flow measurement based on the
requirements. The most commonly used device for low viscosity, transparent
fluids are Glass Tube Rotameter (GTR). The principle of operation for a GTR is
based on the mechanical force balance between the weight of the float and the
magnitude of flow rate. The current work aims at converting the GTR into a
digital device using the halleffct sensor (turbine flow meter). halleffect sensor
will be connected at the inlet of the rotameter & its reading will be calibrated
according to the rotameter reading. Hall effect flow sensor consists of a plastic
valve from which water can pass. A water rotor along with a hall effect sensor is
present the sense and measure the water flow. When water flows through the
valve it rotates the rotor. By this, the change can be observed in the speed of the
motor. This change is calculated as output as a pulse signal by the hall effect
sensor. Thus, the rate of flow of water can be measured. The output reading of
halleffect sensor will be shown at lcd display.
