Series TVA All Fluoropolymer Flowmeters

Series MM Mini-Master® Flowmeter

Series DR Direct Reading Glass Flowmeters

65 mm and 150 mm, Interchangeable Flowtubes, Direct Reading Scales

The Series DR Direct Read Variable Area Glass Flowmeters are ideal for the direct flow measurement of air, water, and other commonly used gases. These flowmeters are designed with direct read scales with no need for correlation charts. They feature borosilicate glass tubes in 150 mm or 65 mm scales with aluminum and SS metering valve options.

Flowmeters are shipped completely assembled and include standard panel mounting hardware for quick installation.

Calibration Options are available in the Accessory tab.

Questions

Question

I am looking to use an "Air" flowmeter RMA-6-SSV to monitor CO2 flow. I am wondering if there are are any concerns or correction factors I need to apply.

Answer

A specific gravity correction factor will need to be considered when monitoring other gases with a meter calibrated for air. The correction factor equation is as follows: Q2=Q1 x sqrt (1/S.G.) Where: Q1= Observed Flowmeter reading Q2= Standard Flow Corrected for Specific Gravity 1= Specific Gravity of Air or Water S.G.= Specific Gravity of media being used in flowmeter originally calibrated for air or water.
This equation can be found in the beginning of the Flow section in the catalog. Alternatively, special ranges and scales can be provided; for specific information please contact our customer service department.
For further information, see our "Tech & Specs" Video Blog: Fix your Flow... Specific Gravity and Pressure Corrections for Variable Area Flowmeters (Episode 4), in Dwyer's Video Library.

Question

Will a DR4244 show an accurate measurement of flow with Methane or is there a converstion We need to use?

Answer

The scale on the DR direct reading flow meters is in millimeters. Therefore, they will come with a conversion chart to convert from millimeters to flow rate for air and water. You will then need to correct that chart to be used for Methane by correcting for the difference in specific gravity. These flow meters can be used to accurately measure the flow of Methane though.
