Fluke 721EX [FLUKE-721EX-3615] Intrinsically Safe Dual Precision Pressure Calibrator, .025% Accuracy, -14 to 36 psi/0 to 1500 psi

The Fluke 721-3615Ex Dual Sensor Precision Pressure Calibrator, 36 psig, 1500 psig is ideal for gas custody transfer measurements with range, accuracy and capability specifically tailored to address gas custody transfers. The 721-3615 has an optional RTD probe for a complete solution to testing flow computers and instruments used in gas flow measurements.

To test a custody transfer flow computer, the user must test and calibrate three key variables or devices: static pressure in the gas pipeline; the difference in pressure across a calibrated orifice; and the temperature of the gas flow (typically ambient temperature). The 721-3615 can be configured with the input sensor ranges that best match the static and differential pressure, as well as the temperature of the gas flow, in order to perform a complete test of the flow computer and its input devices.
