Measurement Science Enterprise, Inc.

MSE specializes in miniaturized optical sensors with three universal characteristics: minimum size, minimum weight, and minimum power consumption.

Velocity Measurement

The miniLDV™, ultraLDV™, microV™, and microS™ are the smallest, lightest, and lowest-power-consumption sensors currently available for optical speed measurement. All three sensor types can measure speed as well as direction, but each is tuned for a specific measurement distance. New for 2008 are the ultraLDV, designed for applications where sensitivity and precision are of utmost importance, the 2D miniLDV, a true two-component sensor, the 3D miniLDV, and the Integrated miniLDV, a miniLDV probe with built-in Processing Engine in a package about the size of a text book. "LDV" stands for "Laser Doppler Velocimeter"—but unlike our competitors', MSE's probes are extremely easy to use because they do not require any complicated alignment after manufacturing.

Sensor	Measurement distance (air)	Application
miniLDV / Integrated miniLDV	33, 50, 100, 150, 240 mm	velocity measurement (surfaces and fluids)
2D miniLDV	50, 100, 150, 240 mm	2D velocity measurement (surfaces and fluids)
3D miniLDV	100, 150, 240 mm	3D velocity measurement (surfaces and fluids)
ultraLDV	150 mm	velocity (with small fluctuations)
microV	7.4 mm	velocity measurement in fluids
microS	75 μm, 135 μm	wall shear stress in fluids

Particle Statistics

The miniPCS™ is a particle sizer/counter based on Mie scattering theory, able to measure particle size over a wide range. Its built-in acquisition electronics make it especially suitable for field tests.

Facilities

The flowLab™ is a table-top-sized water tunnel, perfect for small research projects, expositions, and classroom demonstrations.
