Product description
Variable area metal tube flowmeters for liquids, gases and steam. Metallic or plastic tube with a robust construction, they are particularly suitable for flow measuring under extreme temperature and pressure conditions. High resistance to corrosion. Indication by means of magnetic coupling. Low pressure drop and float damping mechanism to avoid float instability in flowmeters for gas or steam service.
