Barksdale P5 flow switch can be used to measure and monitor low viscosity fluids between 30 and 600cSt, with adjustable switching point and low switching hysteresis. It has a rugged construction and variable mounting position, and it can provide high accuracy and functional safety.
The BFS-20-0 and BFS-20-OL are flow meters designed for measuring and monitoring viscous liquids (30‑600 cSt) in hydraulic, cooling and process‑control applications. They feature a floating‑body measurement principle and are available in brass or stainless‑steel construction.
Key specifications include a viscosity compensation from 30 to 600 cSt, flow ranges of 0.1‑0.8 l/min (BFS‑20‑0) and 0.5‑1.7 l/min (BFS‑20‑OL), maximum operating pressures of PN10 bar and PN16 bar respectively, and standard operating temperatures of 120 °C (optional 160 °C). The devices use a DIN 43650 plug, offer contact ratings up to 250 V/3 A, and are protected to IP65 (IP67 with cable). This manual is written in German.
