Revised Dec-2013
This manual focuses on the hardware aspects of the ControlWave
Electronic Flow Meter (EFM) (called the "ControlWave EFM" or
"EFM" throughout the rest of this manual). For information about the
software used with the EFM, refer to Getting Started with ControlWave
Designer (D5085), the ControlWave Designer Programmer's Handbook
(D5125), and the online help in ControlWave Designer. For information
on the flow measurement application used in the ControlWave EFM,
see the ControlWave Flow Measurement Applications Guide (D5137).
This chapter details the structure of this manual and provides an
overview of the ControlWave EFM and its components.

1.8 Software Tools ................................................................................. 1-8
1.9 Overview of the Gas Flow Measurement Application .................... 1-10
The ControlWave EFM measures differential pressure, static pressure,
and temperature and computes flow for both volume and energy for up
to four meter runs in accordance with API (American Petroleum
Institute) and AGA (American Gas Association) standards.
 Exceptional performance and low power consumption through use
of the ARM microprocessor
 Two CPU options (33 MHz or 150 MHz)
 Two RS-232 and one RS-485 asynchronous serial communication
ports
 Optional Ethernet port (150 MHz CPU only)
 Optional Expansion Communication modules (ECOMs) with
optional built-in modem and/or radio
 Wide operating temperature range: (-40 to +70C) (-40 to 158F)
 Variety of I/O modules (including mixed I/O)
 RTD input
 Lithium coin cell battery (located on the CPU module) provides
battery backup for the real-time clock and the system's static RAM
(SRAM)
 Keypad /. Display for operator interaction.
