Digital Electromagnetic Flow Meter - Allegiance Water 


Management 





The Central Ground Water Authority (CGWA) mandates the installation of digital water flow meters with telemetry for groundwater extraction monitoring. Here are the technical specifications for these meters:

Metering Technology:
Electromagnetic technology.
Flow range for different sizes:
DN40: 0.5 lps to 5 lps
DN100: 3 lps to 30 lps
DN150: 13 lps to 130 lps
Accuracy: Better than ±2% for the operating flow range.
Telemetry System Features:
Tamper-proof design with proper mechanical and electronic sealing.
Data stored in the meter even if telemetry system is off due to power failure.
Transmit the following parameters to a secure cloud:
Cumulative forward flow volume
Cumulative reverse flow volume
Cumulative net volume
Cumulative pump working hours
Meter serial number
Device last calibration date
Borewell ID (provided by CGWA)
Communication:
Data transmitted at least twice daily.
Battery life of at least 3 years with 2 transmissions per day.
Cloud-based Data Management Software accessible via web portal.
