For quick visual checking of liquid flow, this mechanical indicator gives operators a clear, direct reading without electronics. The dome-shaped design provides good visibility of the rotor, and the rotor movement is proportional to flow for quantitative flow indication in water and oil applications.
The family covers DN 8 to DN 25 with G1/4 to G1 internal threads, making it suitable for different pipe sizes in industrial liquid systems. Recommended Qmax reaches up to 26.5 l/min H2O, while rotor start values range from 0.5...5.0 l/min H2O depending on size.
A robust body made from gunmetal and brass supports reliable use in demanding installations. Wetted materials include gunmetal, brass, soda-lime glass, stainless steel, Nylon and NBR, with media temperatures from -20...+100 °C, pressure resistance PN 6 and a pressure loss of 0.05 bar at Qmax.
The device uses a rotor for quantitative flow indication, with rotor rotation proportional to the flow rate.
The family includes internal-thread versions from G1/4 to G1 for nominal widths DN 8, DN 10, DN 15, DN 20 and DN 25.
The flow indicator is specified for liquid media temperatures from -20...+100 °C and pressure resistance PN 6.
The device is intended for water and oils. For media with higher viscosity, the rotor start value tends to be higher.
The installation must avoid inflow from above.
