Description
Panametrics GF868-1-31-21514-0-0-CC-RPT — Ultrasonic Flare Gas Flowmeter
Product Overview
The Panametrics GF868-1-31-21514-0-0-CC-RPT belongs to the DigitalFlow GF868 ultrasonic flowmeter family, designed for gas-flow measurement in flare systems. Unlike a differential-pressure flowmeter that relies on a restriction in the flow path, the GF868 uses ultrasonic transit-time measurement to determine gas velocity. With suitable pipe geometry, transducer selection, and application configuration, the instrument can support flow monitoring in refinery and petrochemical installations where flare-gas measurement contributes to process monitoring, loss accounting, and emissions management.
The GF868 product family supports one-channel and two-channel arrangements, along with configurable enclosure, power-supply, and input/output options. A configured instrument may provide analog inputs and outputs, serial communications, and display functions, depending on the installed options. These capabilities are useful when integrating flow measurements into a plant monitoring or control system. Actual performance, however, depends on gas composition, operating conditions, transducer installation, pipe dimensions, signal quality, and correct entry of the site’s measurement parameters. The complete suffix should therefore be checked before assuming a particular channel count, electrical supply, or I/O arrangement.
For maintenance and procurement teams, Panametrics GF868-1-31-21514-0-0-CC-RPT should be treated as a configured instrument rather than a generic GF868 replacement. Before ordering, compare the full model code and nameplate, inspect the enclosure and electrical connections, and confirm the installed transducers and cable arrangement. If the instrument is intended to replace an existing flare-gas meter, preserve the original site configuration and verify calibration and measurement parameters during commissioning. A meter that powers up successfully is not necessarily ready to deliver reliable process data; its measurement setup and field installation must also be validated.
Product Introduction (Non-Templated)
Flare-gas measurements are only useful when the instrument is matched to the actual gas stream and installation. The Panametrics GF868-1-31-21514-0-0-CC-RPT is part of an ultrasonic flowmeter family developed for flare-gas measurement in demanding process environments.
The platform supports single- and dual-channel configurations, but the full order-code suffix must be checked before a replacement is approved. Verify the supply voltage, enclosure, I/O options, transducer compatibility, and stored site parameters before returning the instrument to service.

Frequently Asked Questions
Q1. What is the -1-31-21514-0-0-CC-RPT used for?
It is a configured model in the Panametrics DigitalFlow ultrasonic flowmeter family, intended for gas-flow measurement with a particular emphasis on flare-gas applications. Confirm the exact configuration from the instrument nameplate and order documentation.
Q2. Is this a one-channel or two-channel flowmeter?
The family supports both configurations. The full suffix supplied here has not been decoded conclusively, so the channel count should be verified from the nameplate, internal configuration, or original order record.
Q3. What power supply does this exact model require?
The family includes AC-powered and optional DC-powered configurations. Do not select a replacement power supply based solely on family-level specifications. Read the instrument nameplate and confirm the ordered power option before energizing the unit.
Q4. Can I connect this flowmeter directly to a DCS or PLC?
The family documentation describes analog I/O and serial communication options. Direct integration depends on the options installed in the specific meter, the DCS/PLC input types, signal scaling, and the communication interface. Verify terminal assignments and configured output ranges before connecting field wiring.
Q5. Can I reuse the existing transducers when replacing the electronics?
Possibly, but compatibility must be confirmed. Check the transducer model, operating frequency, cable type and length, mounting arrangement, pipe dimensions, and gas-service requirements. Reusing transducers without validating these details can lead to weak signals or measurement errors.
Q6. Does replacing the meter preserve the original calibration and site settings?
Not automatically. Site parameters and configuration data must be checked and restored or re-entered as appropriate. Record the existing setup before removal where possible, then verify pipe geometry, gas parameters, channel activation, measurement units, output scaling, and alarm settings during commissioning.
Q7. What should I request when purchasing surplus or refurbished stock?
Ask for photographs of the full nameplate and suffix, confirmation of channel and power configuration, enclosure details, transducer and cable compatibility, and available functional-test records. For a critical flare-gas measurement point, request evidence that the supplied configuration matches the existing installation and establish how calibration and acceptance testing will be handled.
