EN 655 Flow Indicators Plastic, with Rotor


ELESA original design
code: HVF

Product description


When EN 655 flow indicators 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.

EN 655 flow indicators 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 212 °F (100°C).

The flow indicator can be mounted in any position. The direction of flow and the installation position are irrelevant.
