TSI’s LDV Blood Flowmeter

  • John A. Borgos
Part of the Developments in Cardiovascular Medicine book series (DICM, volume 107)


Since its incorporation in 1961, TSI’s primary business has been identifying requirements for the measurements of details of fluid flow, and then developing solutions to meet these needs. The company’s earliest products were a series of thermal anemometers used for measuring the flow of hot gases. This product line soon expanded into a broad line of hot wire and hot film probes and electronics for fluid flow measurement in research, medical, and industrial applications.
