Master Metering using your SCADA System

2 499 vues

Publié le

An educational presentation of the latest technology for integrating master flow meters into a SCADA system.

Three case studies are presented, each detailing a different SCADA communication backbone: FM Telemetry Radio-Modem, Cellular/GSM/GPRS Modem, and Extraterrestrial Satellite Modem.

The metered liquid in the case studies is potable water, although the technology is applicable to wastewater, oil, gas, steam, etc..
