Utilising the standard Valeport 125mm diameter impeller , the Model 1features speed and direction parameters as standar with further options of . Sorry, you have entered an invalid value ! The instrument is used for the accurate determination of the current velocity in water ways, channels, rivers and the sea. The meter can also be applied in polluted water currents.

The measurements are executed with the propeller mounted on the rod(s) or connected to a cable. The current velocity meter has a measuring . The Aquadopp is probably the most versatile single-point current meter on the market. The system electronics integrates accurate Doppler velocity measurements with standard sensors such as temperature, pressure, tilt, and compass.

It is low maintenance, has . Instructions on flow Measurement using current meter method. Read this article to learn about the measurement of velocity by current – meter. The velocity of flow at any point in the open channel can be most accurately and conveniently determined by means of a mechanical device named current – meter.

Global Water offers a unique, price competitive current meter for stream flow measuring. Current meter is a measuring instrument used. The USGS Type AA current meter is commonly known as the Price-type current meter. This current meter is suspended in the water using a cable with sounding weight or wading rod (taking the tail section off) and will accurately measure streamflow velocities from 0. The Pygmy Meter is scaled two-fifths as large as the standard Type AA current meter.

It does not have a tailfin assembly and is used only for measuring shallow streams with the wading rod. Its range of operation is 0. Define current meter : an instrument for measuring the velocity of flow of a fluid (as water) in a stream. An ideal current meter , whether mechanical or electromagnetic, should respond instantly and consistently to any changes in water velocity, and should accurately register the desired velocity component. Additionally, the meter should be durable, easily maintaine and simple to use under a . There are many factors to consider when selecting the proper current meter for your application. In general, you should know if you will be measuring current from an overhead structure or while wading.

It also helps to know the approximate speed of the water to be measured. This is because there are specialty meters . The Price meter , a cup-type instrument with a vertical axis, was developed by USGS and is commonly used for irrigation water measurement. This meter has the following general features: vanes to keep the front of the meter headed into the current , either a cable or a rod for handling the meter , weights for sinking the meter.

A ID: 5- Put a current meter anywhere with this very handy display.

This panel meter requires a DC voltage to run, and then has two thick gauge wires to measure current draw. A shunt is already on board so its very easy to hook up!
