Overview
The King Instrument SCFM-AIR-STP 0-4 flow meter is a precision air flow measurement instrument engineered for reliable performance in pneumatic applications. This rotameter combines a clear acrylic metering tube with a direct-reading float scale, providing technicians and engineers an immediate visual indication of air flow rates. The unit is calibrated for air at standard temperature and pressure (STP) and includes a Kuri Tec K1136 connection hose assembly for quick integration into existing systems.
Key Features
- 0–4 SCFM measurement range optimized for low to medium flow pneumatic applications
- Acrylic tube construction with clear visibility for easy float reading
- Direct-reading float design—no external instrumentation required
- STP-calibrated scale for accurate air flow measurement
- Includes Kuri Tec K1136 hose assembly for immediate deployment
- Compact, durable design suitable for lab, test bench, and field use
