8 Overview
1758-FLO DataSite controllers
In addition to the features listed in preceding sections, the 1758-FLO DataSite
controllers provide the additional feature of being able to calculate gas flow.
1758-FLO DataSite controllers contain the 1758-FLO flow measurement
algorithm which conforms to the following standards:
• AGA-3 (1992 version) (1)
orifice metering of natural gas and other
related hydrocarbon fluids;
• AGA-7 (1)
measurement of gas by turbine meters;
• AGA-8 (1)
compressibility factors of natural gas and other related
hydrocarbon gases.
The 1758-FLO controller can be configured by using the DS FloConfig
software. This tool provides functions such as reading and revising parameters,
reading historical data and monitoring measurement results.
Features at a Glance
• Advanced 32-bit processor with embedded real-time multi-task
operating system (RTOS).
• 8 analog inputs (2 with point-to-point HART interface), 2 analog out, 8
discrete inputs, 4 discrete outputs, and 3 pulse inputs.
• Embedded Ethernet, two serial ports (RS232/RS485) and one HART
multi-drop interface; native protocols include Modbus RTU, Modbus
ASCII, and Modbus TCP.
• 6M Flash, 1M RAM, and 32K ferroelectric RAM for long-term storage
of configured parameters.
• HiBeam technology that allows the DataSite controller to act as a web
and event-based data server. HiBeam also has tools for interfacing with
your controller-based data through a standard web browser.
• Conformity to IEC61131-3. Supports LD, FBD, IL, ST and SFC
programming languages.
• Isolation of power supply, signal output and input terminals from the
main control circuit.
• Standard industrial design and DIN rail mounting option, which are
convenient for field installation and configuring interior hardware.
(1) The 1758-RTU controller does not have AGA-3, AGA-7 or AGA-8 calculations.
