An instrument for measuring currents, especially the force or intensity of electrical currents; a galvanometer.

An instrument for measuring the velocity of the blood current in the arteries.

An instrument designed for the measurement of non-Newtonian and Newtonian viscosities.

an instrument to measure flow of viscous substances

an instrument that measures the flow behavior of materials.

a device which exposes a small sample of compound to vulcanization temperature and tracks its changes in viscosity as it cures, to produce a kind of processing profile of the material; available as oscillating disk rheometers (ODR) and the newer moving die rheometers (MDR)

instrument that enables measurement of rheological characteristics of a substance such as Viscosity, shear rate, shear stress, strain.

Rheometers are viscometers which are able to measure visco-elastic properties of materials rather than viscosity alone.
