The KOBOLD DAA Series visual flow indicator with rotor features a self-cleaning mechanism to ensure full visibility of the rotor at all times. Most other sight flow indicators suffer problems of poor indicator visibility with use, resulting from dirt build-up on the viewing window. For such a sight flow indicator to be cleaned, it must be removed and restored at some convenient time, such as during plant shut-down. Unfortunately, dirt build-up does not typically schedule itself to correspond with planned shut-downs. Enter the KOBOLD DAA Series visual flow indicator with rotor and self-cleaning mechanism. Simply twist the sight glass, and 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 medium flow. This process may be repeated as often as desired with no fuss and no downtime. The DAA Series visual flow indicator with rotor and self-cleaning mechanism is available with brass or stainless steel fittings with female threads 1/4" to 1-1/2" NPT. The body is made of a hard glass (Duran), and the rotor and wipers are synthetic. The device is kept tight and rotatable through the use of low friction O-rings.
