Overview & Engineering Methodology
Central Ground Water Authority (CGWA) guidelines make calibrated flowmeters with digital telemetry mandatory for all ground water abstracting industrial and commercial units. Allegiance Water provides end-to-end flow measurement solutions ranging from 15 NB to 1000 NB pipe sizes. Our electromagnetic meters feature SS316L electrodes, PTFE/Rubber linings, RS485 MODBUS communication, and 4-20mA outputs, paired with GSM/GPRS IoT telemetry gateways that stream live abstraction data directly to CGWA cloud servers.
