HUBA Flow Sensor 240.915461K
Product Description
The Vortex 240 flow sensor is based on the vortex principle and provides reliable measurement results for liquid media with varying specific viscosities (from antifreeze to drinking water). The sensor has no moving parts, ensuring a long service life and high accuracy. It delivers accurate and stable flow measurements even under harsh conditions. A key highlight of the Model 240 sensor is its exceptional resistance to high system pressures and medium temperatures. It also features high accuracy and leak-proof performance. It covers a wide range of applications, from smaller diameters for measuring DN 6 pipes to large-diameter applications in industrial processes. Its compact design allows for direct installation on a manifold, ensuring efficient use of space.
