Electromagnetic Flow Meter - Allegiance Water Managements
Central Ground Water Authority (CGWA) guidelines, here are the specifications for Electromagnetic Flow Meters used for groundwater extraction monitoring:
Meter Type: The flow meter should be either an Electromagnetic flow meter or an Ultrasonic meter.
Accuracy: The meter must have an accuracy class of 2 (T50) as per ISO 4064:2014 standards.
Flow Range: The flow range accuracy should be better than ±2%.
Size Options:
DN40: Flow range from 0.5 lps to 5 lps
DN100: Flow range from 3 lps to 30 lps
DN150: Flow range from 13 lps to 130 lps
Power Source: The meter can be either battery operated or powered through a UPS.
Ingress Protection: The meter should comply with IP 68 ingress protection.
Leak and Flow Detection: The meter should be capable of detecting leaks, zero flow, and high flow.
Telemetry System:
The meter should transmit data to a secure cloud.
Transmission frequency: Minimum 2 times per day.
