DAA Series Self-Cleaning Sight Glass/Rotor Flow Indicator

Brand: KOBOLD Instruments, Inc

The KOBOLD DAA visual flow indicator with rotor features a self-cleaning mechanism to ensure full visibility of the rotor at all times.

Typical sight flow indicators suffer from poor indicator visibility through normal use from build-up that impedes observation of the rotor through the viewing window.

Typically, for a sight flow indicator to be cleaned, it must be removed from the pipeline, cleaned and then replaced at some specified time, such as during plant shutdown.

Unfortunately, dirt build-up does not typically schedule itself to correspond with planned shutdowns.

Enter the DAA flow indicator. Simply twist the sight glass and the integral wipers clean the flow indicator’s viewing area to allow unobstructed observation of the rotor.

The offending contaminants are then simply washed away by the media flow. This process may be repeated as often as desired with no fuss and no downtime.

It is available with brass or stainless steel fittings with 1/4" to 1-1/2" NPT female threads. It is also available without a rotor for observation of fluid condition.
