Abstract: A flow sensor includes a fluidic component, such as a tube, a heat source, an upstream temperature sensor, and a downstream temperature sensors. The fluidic component defines a flow path having inlet and outlet ends disposed closer to each other than to a mid-point of the flow path. The heat source and the upstream and downstream temperature sensors are disposed in thermal communication with a fluid in the flow path.

Abstract: A method and apparatus for measuring the viscosity of a sample solution which comprises an input tube for transporting a sample solution flow towards a splitter for diverting input flow into two distinct flow streams where three capillary tubes are located in the two flow streams placed downstream from the flow splitter, where each flow stream has one or two capillary tubes a delay volume, and a flow through transducer having hydraulic connections placed in one stream or in two streams used for measuring the pressure difference across the capillary tubes.
