| 2 | 1 | Pavneet Kaur | Flow meter – for checking the flow of water in pipe |
| 3 | 1 | Pavneet Kaur | |
| 4 | 1 | Pavneet Kaur | CSR bought ultrasonic flow meter from Chennai and the company (company name? )trained Bala and Vijai(CSR) on how to set it up. |
| 5 | 1 | Pavneet Kaur | we tested in the west water system pump in csr. then we test in many more place . |
| 6 | 1 | Pavneet Kaur | ami, aurodam and buddha garden borewell pumps . we got request from the water service |
| 7 | 1 | Pavneet Kaur | Cross check they flow meters . |
| 8 | 1 | Pavneet Kaur | so before that we want to know how our meter works. |
| 9 | 1 | Pavneet Kaur | so we tested in our tank . the pump pumping from our sump tank so the flow will be stranded. when you pump in the bore well the flow goes up and down. |
| 10 | 1 | Pavneet Kaur | we tested two times in 15 minutes.and one time 30 minutes,so we got variation between this three. |
| 11 | 1 | Pavneet Kaur | we find 1,5 % error but the flow meret they said 1 % error only. |
| 12 | 1 | Pavneet Kaur | we cross checked the flow meter of the water service we find some error in they meter also. |
| 13 | 1 | Pavneet Kaur | we tried they bore well flowmeter and they sump tank flow meter also.and we find some error also in they meters. |
| 14 | 1 | Pavneet Kaur | then we find some error in (AVWS) meter also. |
| 15 | 1 | Pavneet Kaur | It is used to check the flow of water in pipe |
| 16 | 1 | Pavneet Kaur | tools used |
| 17 | 1 | Pavneet Kaur | First the outer diameter of the pipe has to be entered in the device. It is measured using Vernier caliper |
| 18 | 1 | Pavneet Kaur | Then the thickness of the pipe is set which is also measured using vernier |
| 19 | 1 | Pavneet Kaur | Also the device asks for the material of the pipe. If the pipe material is know it can be set and if it not know then there is an option which is other (mostly PVC, HDPE, and iron) |
| 20 | 1 | Pavneet Kaur | After entering these details the device gives the spacing for the sensors. There are 2 sensors up and down which has to be fixed accordingly |
| 21 | 1 | Pavneet Kaur | When the sensors are fixed the motor is turned on and the sensors send reading to the display device |
| 22 | 1 | Pavneet Kaur | This is noted down once every minute and taken for 15 to 30 minutes. Then the average of this is determined. This is done because of the variation in the flow. This gives the flow rate in 1 hour. |
| 23 | 1 | Pavneet Kaur | This was done in different places to check to flow rate |
