DAA Flow Indicator

Brand: KOBOLD Instruments, Inc.

The KOBOLD flow indicators DAA can be installed in pipe-works for fluids. The DAA are available with both sides female threads in brass or stainless steel. The medium flow is indicated by a plastic rotor installed inside a hard glass body (borosilicate glass).

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. By installing the KOBOLD flow indicator DAA, these problems are avoided.

With a twist of 180° of the sight glass, integral wipers clean the viewing area do allow unobstructed observation of the rotor. The offending contaminants are then simply washed away by the medium flow. The device is kept tight and rotatable by hand by the use of low friction O-rings.
