Water Velocity Measurement

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.

Water velocity measurement.

The sensor uses advanced technology to measure velocity with a laser beam at single or multiple points below the surface of the wastewater stream. 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. Pitot tubes also called pitot static tubes are used for example to make airflow measurements in hvac applications and for aircraft airspeed measurements. Pitot tubes are used in a variety of applications for measuring fluid velocity.

In the simplest method a current meter turns with the flow of the river or stream. Q 2 3 cd b 2 g 1 2 h3 2 1. 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. Ott svr 100 is a simple non contact compact surface water velocity radar sensor.

The global water flow probe is a highly accurate water velocity instrument for measuring flows in open channels and partially filled pipes. This is a convenient inexpensive method for measuring velocity at a point in a flowing fluid. 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. Surface velocity radar for measuring open channel flow.

Global water flow probes are highly accurate water velocity instruments for measuring flow in open channels and partially filled pipes. The depth of the water is also measured at each point. The current meter is a very effective device for the measurement of velocity of flowing water. The flow rate measurement in a rectangular weir is based on the bernoulli equation principles and can be expressed as.

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 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 sensor uses an ultrasonic level sensor to measure the level and determines a sub surface point to measure velocity.
