Q1. Can the Rosemount 8800D measure argon gas flow?
Yes. The Rosemount 8800D Argon Flow Meter uses vortex technology, which is suitable for inert gases such as argon, nitrogen, and air. It provides accurate volumetric flow measurement.
Q2. Does the 8800D measure mass flow or volumetric flow?
The 8800D measures volumetric flow. To obtain mass flow, you must apply density compensation or use a Coriolis flow meter (e.g., Rosemount 8742C) for direct mass flow measurement.
Q3. What is the accuracy of the 8800D for gas applications?
For gases, the typical accuracy is ±1% of reading under proper installation and operating conditions.
Q4. What pipe sizes are supported?
The 8800D is available in sizes from ½ inch to 12 inches (15–300 mm). Larger diameters can be handled using insertion-style vortex meters.
Q5. What are the installation requirements?
The meter requires straight pipe runs to ensure stable vortex formation:
Q6. Is the 8800D suitable for corrosive or dirty gases?
It is best suited for clean, non-corrosive gases like argon. For corrosive or particulate-laden gases, material compatibility and potential clogging should be evaluated.
Q7. What outputs are available?
The 8800D provides standard 4–20 mA, HART®, FOUNDATION™ Fieldbus, and Modbus communication options.
Q8. How does the 8800D compare with other Rosemount flow meters for argon?
