Arrangement for highly dynamic measuring volume flow of flowing media e.g. hydraulic fluid and oil, has insert at distance space of connections within main channel and possesses channels, which are concentric to longitudinal axis direction

摘要

The arrangement has a sensor element provided at an adjacent flow channel. A main flow channel comprises cross-sectional surfaces of the adjacent flow channel. Fluid connections are arranged at distance from each other between the main flow channel and the adjacent flow channel. The sensor element forms viscosity-dependent throttle at the main flow channel in a dimension-limited manner. An insert is provided at a distance space of the connections within the main channel and possesses spiral individual channels (9), which are parallel or concentric to a longitudinal axis direction. The insert is formed as a metal structure or a plastic injection part or a structure of ceramic material.
