ADS Environmental Services FlowAlert QR 775011 A2 - Manual (Page 18)

2-6 ADS FlowAlert Manual
includes the monitor clock, random access memory (RAM), and
Flash. The monitor uses RAM while taking readings and
processing the flow data. The RAM then downloads the data to
Flash, or non-volatile memory, which also stores the monitor
firmware and configuration information. Flash ensures the monitor
maintains the data during battery pack replacement or a power
failure.
Input Device Processing
The input component of the board controls the processing of the
pressure depth sensor and the float switch. It initiates pressure
depth sensor readings and requests for the float switch state. The
board also processes the solicited (and unsolicited) data received
and stores it in the monitor memory.
Communications
The communications component of the board provides multi-
tasking/handling of all communications processes. It interfaces to a
landline or wireless modem (based on the model of FlowAlert), as
well as manages local serial communication requests. The
communications component also is responsible for gathering real-
time information from the other components on the board.
Voltage Regulator
The voltage regulator regulates and distributes power supplied from
the battery pack to the analog, communications, and DSP
components on the board.
Communications
ADS offers two remote communication options for the FlowAlert
monitor. The first option involves wireless communication over the
cellular network using GPRS (General Packet Radio Service)
through the modem in the monitor. GPRS facilitates high-speed,
low-cost, efficient TCP/IP communication in areas with AT&T
