Ultrasonic flowmeter

1.Ultrasonic Flowmeter is a type of flowmeter that determines the flow velocity of fluid using ultrasonic soundwaves .
2.Ultrasonic Flowmeter works on the principle of Transit Time Difference Method , where we use Ultrasonic Transducers to emit and detect the ultrasonic waves.

2. Ultrasonic Flowmeter U ltrasonic Flowmeter  is a type of flowmeter that determines the flow velocity of   fluid using ultrasonic soundwaves   . Ultrasonic Flowmeter works on the principle of Transit Time Difference Method , where we use Ultrasonic Transducers to emit and detect the ultrasonic waves.

3. Principle : Transit Time Difference Method Flow velocity of Fluid is directly proportional to difference in time taken by ultrasonic waves to traverse between the transducers.

4. Formulae: v / (2D) = Difference in Time intervals [ T 1 -T 2 ] v = Average Flow Velocity of Fluid c = Velocity of Sound in Fluid Medium D = Diameter of pipe

8. Procedure Open the Valves accordingly to ultrasonic flowmeter setup. Switch on the power supply so that water gets pumped into the ultrasonic flowmeter setup . First Perform ZERO FLOW TEST for Confirmation. Take the reading displayed on the Software and also note down the Loadcell reading . Compare both the flow rates.

9. Requirements 1.5 hp water pump - Rs.7600 Two ultrasonic transducers Weighing Machine TDC1000_TDC7200 EVM Kit - Rs.8050 Pipe of 1 inch Diameter Four control Valves Two tanks(water sump)

10. Work Progress : We have finalized the design model along with its frame . Presently We were working on the functioning of TDC 1000_TDC7200 EVM Kit and how to run this on the Software.

11. Difficulties : Mounting the transducers exactly at 45º angle to the pipe. Inserting the Transducers and sealing it firmly without any leakage, without disturbing the flow parameters.

12. Improvements : We can improvise this by, replacing Laptop interface by r asberry pi minicomputer with an LCD Display. Acrylic Tank with calibration scale helps the user to calculate the flow rate manually.
