Direct Reading, 127 mm Scale, ±10% FS Accuracy

Be the first to review this product

Series DR4 Glass Flowmeters offer a simplified solution to the problem of fluid flow indication at higher capacity levels. Flowmeters have a direct reading scale for air or water and are designed to withstand even the harshest industrial applications. Permanently fused ceramic scale has integral float guides for optimum float performance. Reflective plastic background and 1.5 X magnification lens reduces eye fatigue and allows for more accurate readings. Units include a safety blow-out back panel for additional protection.

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.
