Water Velocity Measurement

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.

Water velocity measurement.

Ott svr 100 is a simple non contact compact surface water velocity radar sensor. Q 2 3 cd b 2 g 1 2 h3 2 1. Most velocity based meters have an adjustment vane for calibrating the meter to the required accuracy. In the simplest method a current meter turns with the flow of the river or stream.

Pitot tubes also called pitot static tubes are used for example to make airflow measurements in hvac applications and for aircraft airspeed measurements. The depth of the water is also measured at each point. There are several types of meters that measure water flow velocity including jet meters single jet and multi jet turbine meters propeller meters and mag meters. 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 current meter is used to measure water velocity at predetermined points subsections along a marked line suspended cableway or bridge across a river or stream. 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. All types of the instrument have common features. Global water flow probes are highly accurate water velocity instruments for measuring flow in open channels and partially filled pipes.

The global water flow probe is a highly accurate water velocity instrument for measuring flows in open channels and partially filled pipes. 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. The current meter is a very effective device for the measurement of velocity of flowing water. Pitot tubes are used in a variety of applications for measuring fluid velocity.

This is a convenient inexpensive method for measuring velocity at a point in a flowing fluid. The flow rate measurement in a rectangular weir is based on the bernoulli equation principles and can be expressed as. The sensor uses an ultrasonic level sensor to measure the level and determines a sub surface point to measure velocity.
