Kobold Instruments - DAA-5115 | DAA Paddle Wheel Flow Indicator

DAA-5115 is a self-cleaning sight flow indicator with 1/2" NPT connections. Wetted parts are brass, POM with NBR seals, terminating in 1/2" NPT connections. Its twist-to-clean wipers clear the borosilicate viewing window mid-process, keeping the rotor in view without a shutdown. It is rated to 232 PSIG and 212°F for fluids to 150 cSt. On 1/2" NPT liquid lines, it suits dependable visual flow indication in process skids. The KOBOLD DAA flow indicator solves one of the most persistent challenges in visual flow monitoring—window fouling—through its innovative self-cleaning mechanism that maintains clear visibility without requiring system shutdowns or maintenance interventions. With a simple twist of the sight glass, integrated wipers remove accumulated residue from the borosilicate glass cylinder, allowing the fluid flow to wash away debris and restore optimal visibility of the rotor's movement for reliable operation. Available in brass or stainless steel construction with connection sizes from 1/4" to 1-1/2" NPT, this versatile indicator accommodates applications ranging from 0.11 GPM to 26.4 GPM while handling pressures up to 232 PSIG and temperatures up to 212°F. The brightly colored rotors (red for smaller models and white for larger sizes) provide distinct visual confirmation of flow status, while the universal mounting design ensures straightforward installation in both new and existing systems. By eliminating costly downtime and maintenance associated with traditional flow indicators, the DAA delivers continuous operational reliability in industrial process monitoring applications where maintaining visibility is critical to effective flow verification.
