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

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.
