TURBINE FLOW METER (VARIANTS) Russian patent published in 2005 - IPC

FIELD: measuring equipment.

SUBSTANCE: device has body with measuring channel, in which serially mounted are stream rectifier, shaft, on which bladed turbine is rigidly held with ferrite rod pressed in hub thereof, self-induction coil, through which shaft passes, assembly for taking signal and micro-power generator. Measuring channel, behind self-induction coil, has device, made of elements, at least one of which is made of thermo-sensitive material and can alter shape with changes of temperature or under effect from external force. According to second variant, in turbine flow meter additionally mounted are second shaft in conjunction with first shaft, self-induction coil and signal-taking assembly, while on second shaft, in shafts conjunction area, a device is held with functions of thermo-capturing, elements of which can change shape under effect from temperature or external force.

EFFECT: broader functional capabilities.
