Water Velocity Measurement Instruments

Beginning then with the first electronically operated sailboat speedometer and continuing to expand into open channel velocity measurement.

Water velocity measurement instruments. The ysi services team provides complete installation setup and indexing of these instruments ensuring that the manufacture s recommendations are met. There are various forms of current meters and the most commonly used ones are a the price current meter and b propeller type current meter. The global water flow probe is a highly accurate water velocity instrument for measuring flows in open channels and partially filled pipes. Designed for measuring flow in open channels and rivers where reliable velocity data is required continuously during floods or periods of high concentrations of suspended sediments.

The water velocity probe consists of a protected water turbo prop positive displacement sensor coupled to an expandable probe handle with a digital readout display. Sontek a xylem brand manufactures a variety of water velocity measurement instruments and is an industry leader in acoustic doppler profilers adp s and acoustic doppler velocimeters adv s. These instruments are currently 2012 the most commonly used velocity meter for index velocity stations. Acoustic doppler velocity meters advms are acoustic current meters that use the doppler principle to measure water velocities in a two dimensional plane.

The model 2100 instrument was introduced in 1980 and has been one of the most reliable water current measuring instruments in the us. Ott svr 100 is a simple non contact compact surface water velocity radar sensor. The water velocity probe consists of a protected water turbo prop positive displacement sensor coupled with an expandable probe handle ending in a digital readout display. The newest addition is a data logging flow meter the model 3000.

The water velocity probe consists of a protected water turbo prop positive displacement sensor coupled with an expandable probe handle ending in a digital readout display. Global water flow probes are highly accurate water velocity instruments for measuring flow in open channels and partially filled pipes. This type spiral paddle type velocity apparatus for testing water flowing scheduled the measuring point time average velocity. This instrument characteristics is small volume light and modelling compact structure precision carrying use convenient applicable to small rivers the river sell water irrigation and drainage channels of ford water conservancy survey runoff experiment etc and is widely used in the test tube of small and medium sized pump station efficiency flow.

All types of the instrument have common features.
