Frequently Asked Questions (FAQ)
Flow computers require accurate measurement of both differential and static pressure. The 3630 model provides a low-pressure sensor for differential and a high-pressure (3000 psi) sensor for static, allowing both to be calibrated at the same time in the field.
The "EX" designation means the device is intrinsically safe. It is certified for use in Zone 1 explosive atmospheres, common in oil and gas production, where standard electronics could ignite hazardous gases.
The total shipping weight is approximately 5.0 lbs (2.3 kg). This includes the calibrator, soft case, test leads, clips, batteries, and the NIST-traceable calibration paperwork.
Yes. The Fluke 721EX-3630 supports the optional Fluke 720RTD probe, which allows for temperature measurements with 0.1°C accuracy—essential for complete gas flow calculation.
