Series DR Direct Reading Glass Flowmeters |
| 65 mm and 150 mm, ±5% FS Accuracy, Interchangeable
Flowtubes |

  Use
Series DR Glass Flowmeters to accurately measure flow rates
of air or water with the convenience of a direct reading scale.
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. Flowmeters are shipped completely
assembled and include standard panel mounting hardware for quick
installation.
Add suffix "M" for metric scale.
* Denotes glass float.
† Metric models use ccm as unit of measure. |
