![]() ![]() The measurand (mass flow rate) is forced through this tube. To harness this force for the purpose of measurement, a rotating tube may be used. The sideways motion component of the swirl may be attributed to the Coriolis (pseudo)force. Of following a straight path it “swirls��? (in a motion). This is apparent in a hurricane on the earth (a rotating system) where, when air flows towards a low-pressure region from surrounding areas, instead Additionally, Coriolis meters have a quick response, and can principally afford an all-metal-no-sliding-parts fluid interface.Ī Coriolis force is a pseudo-force that is generated when a mass is forced to travel along a straight path in a rotating system. This also makes Coriolis meters versatile – the same instrument can, without need for factory calibration, measure diverse fluid media – liquids as well as gases. density, state, temperature, heat capacity, viscosity, etc.) of the medium that they measure. ![]() Flowmeters based on the Coriolis effect offer the most direct sensing of the mass flow rate, and for this reason do not need complicated translation or linearization tables to compensate for other physical parameters (e.g. The accurate and quick measurement of small mass flow rates (~10 mg/s) of fluids is considered an “enabling technology��? in semiconductor, fine-chemical, and food & drugs industries.
