TSI’s LDV Blood Flowmeter

  • Chapter
Laser-Doppler Blood Flowmetry

Part of the book series: Developments in Cardiovascular Medicine ((DICM,volume 107))

Abstract

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.
