The Kobold DAA flow indicator utilizes a sight glass and optional plastic rotor to provide a visual indication of flow. The DAA features a self-cleaning mechanism insures full visibility of the rotor at all times. Most types of known flow indicators suffer problems of indicator visibility with use. These problems are the result of dirt build-up on the viewing windows of these devices. With a simple twist of the sight glass on Kobold DAA flow indicators, integral wipers clean the viewing area to allow unobstructed observation of the rotor. The contaminants are then washed away by the medium flow. This process may be repeated as often as desired with no downtime.
The Kobold DAA has flow ranges from 0.11-3.17 GPM up to 1.06-58.12 GPM, a maximum temperature of 210°F, and a maximum pressure of 230 psig. This Kobold flow indicator is available with brass or stainless steel fittings with female threads from 1/4" to 1-½" NPT. The body of the DAA is made of a hard glass (Duran) and the rotor wipers are synthetic. This device is kept tight and rotatable through the use of low friction o-rings.
