The telemetry system units shall be battery operated or through external power supply. The metering data should be stored in the meter even if the telemetry system is off due to power failure. (b) Sealing : The meter and telemetry system shall have proper mechanical and electronic sealing (through software) arrangement. Any attempt to open the meter or system enclosure should physically damage the tag. Compliance : The meter shall preferably be manufactured as per ISO 4064: 2014 Standards and shall have IP 68 ingress protection. Accuracy : The meter shall be of accuracy better than ± 2% for the operating flow range (from 10 % to 100 % of maximum flow rate).Test certificate : The meter manufacturer shall submit the latest test/calibration certificate of the meter, from Fluid Control Research Institute (FCRI) / National Physical Laboratory (NPL) or any third party laboratory accredited by National Accreditation Board for Testing and Calibration Laboratories (NABL), for every meter.Parameters to monitor : The meter (since installation of the requisite water meter) shall transmit the following parameters to a secure cloud : - (a) Timestamp (b) Cumulative forward flow volume (c) Cumulative reverse flow volume (d) Cumulative Net volume (e) Cumulative pump working hours (f) Meter serial number (g) Device last calibration date (h) Borewell id (Provided by CGWA)Cloud : The Communication / telemetry data should be directly captured in a secure cloud. The cloud service provider should be empaneled with The Ministry of Electronics and Information Technology (MeitY). Transmission frequency : The data shall be transmitted minimum 2 times in a day.Battery life : In case of battery operated meters the battery shall run at least for a period of 3 years with 2 transmissions per day. The battery shall be replaceable without any data loss.Data acquisition : The meter shall be supplied with complete AMR / AMI system with Data Management software. The Data Management Software must be capable of running on a standard PC. The Data Management Software should be cloud based and should have web portal access so that user can view customer data through browser. In addition to above, Data Management Software will be installed on Server placed in Central Data Base/Control Room, and the software may have option for individual customer to view their meter consumption data through Web portal. Consumer, engineer and manager screens shall be available separately.Data Collection Unit shall be capable of taking data from meter, pump etc. and should be posted in Data Management Software. Real-time data to CGWA : The un-tampered data from the secure cloud shall be sent to Central Ground Water Authority (CGWA) real-time data management platform once it is ready. Proper cyber security measures shall be taken in the secure cloud.Note : - The quoted Rate to be included for the following jobs no additional Payment will be considered in any case.(a) Taking up/down the existing pipe/fixing and any additional job & material required for fixing and testing of Digital flow meter.(b) Additional Pipe requried if any size.
