Product description
When flow indicators GN 655 are used, a rotor rotates above a minimum volume flow rate Q, depending on the medium and its viscosity. The flow rate is visible from all sides.
Flow indicators GN 655 have a high chemical resistance and are also suitable for liquids containing glycol. Please contact us if you need any additional information about media and pressure resistance. The flow indicators can be used in temperatures of up to 100 °C.
The flow indicator can be mounted in any position. The direction of flow and the installation position are irrelevant.
