"Wireless TransCeiver (WTC)"

"Telephone Lines are for the Birds"

As leased dedicated phone lines are becoming more difficult to acquire, AGM customers are switching to wireless data communications using AGM's Data Handlers (DH) and Spread Spectrum Radios (SSR).

"Beep Alert"

The Data Handler, when combined with your existing  pager system, provides a convenient, low cost way to detect and broadcast remote site alarms such as a pump failure or unauthorized intrusion.

"AWT"

Erratic flow signals can result in unnecessary wear and tear on chemical feed equipment.

Use the Data Handler application, "Average with Time", to smooth the signal.
