ROTAMETER - 0.02 - 0.25 L/MIN ACCURACY ±2.5% FSD

Reading the flow rate
Before taking a reading ensure that the rotameter is positioned on a level surface.

The reading is taken from the top level of the float. The operator should read the scale at eye level, not from above or below, to ensure the accuracy is maximized.

The accuracy of rotameters is impacted if the float is not steady. Ensure that the float is spinning freely and is not oscillating up and down before taking a reading.

Optional accessories
717-511 - Tubing adapter for small sample tubes. Enables leak free connection of small diameter sorbent tubes to the rotameter.
