EF122 Variable Area Flow Meter with Needle Valve 80 – 800 L/h (AIR)
Achieve precise, stable air flow control with an integrated needle valve and robust construction.
The Ensim EF122 variable area flow meter provides highly accurate flow management in industrial air lines, and its integrated needle valve allows you to control flow rate in the finest detail. In addition, the borosilicate glass tube and 316 stainless steel float structure deliver long-lasting performance under challenging conditions. Furthermore, this flow meter withstands up to 16 bar pressure, while Viton seals ensure excellent leak-tightness. Moreover, the 100 mm tube length enables clear readings and the 2.5 accuracy class produces reliable results.
The EF122 operates on the variable area principle, where a float rises in a tapered borosilicate glass tube as air flows upward, indicating the flow rate directly on the scale. The 316 stainless steel float and Viton seals resist corrosion and wear, while the 1/4″ BSP or NPT connections enable easy integration into existing pipelines. Consequently, the compact design allows quick installation in tight spaces, and the needle valve provides fine adjustment for stable, repeatable measurements in laboratory and industrial processes.
