The Fluke 721-1603 is ideal for gas custody transfer measurements with ranges, accuracies and capabilities specifically tailored to address gas custody transfers. The Fluke 721-1603 has an optional RTD probe for a complete solution for testing flow computers and instruments used in gas flow measurement.

The Fluke 721-1603 Dual Pressure Calibrator is ideal for natural gas custody transfer applications. To test a custody transfer flow computer the user needs to test and calibrate three key variables or devices, static pressure in the gas pipeline (0-1500 psi, 0 to 100 bar typical), the difference in pressure across a calibrated orifice (0-10 psi, 0 to 760 mbar differential pressure typical) and the temperature of the gas flow, typically ambient temperature (-40 to 50C). The Fluke 721-1603 can be configured with input sensor ranges that best match the static and differential pressure as well as the temperature of the gas flow to perform a complete test of the flow computer and its’ input devices.
