Velocity Meter
A Digital Water Flow Meter
The digital water flow meter consists of a turbo prop sensor which is attached to a handle that is expandable and has a digital readout display. The Global Water Flow Probe is a very accurate water flow instrument that measures the flow in open channels as well as in partially filled pipes.
The digital water flow meter has true velocity averaging and can measure flows in a very accurate manner and is used for measuring flows in rivers and streams as well as monitoring velocity in ditches as well as canals. The digital flow meter also has many features to it including easy flow monitoring, digital display in ft/second or meters per second, does not weigh much and is reliable as well as rugged and is used by water professionals all across the world.
Debris Shedding Turbo-Props and Telescoping Handle
This digital water flow meter also has debris shedding turbo-prop and a telescoping handle with staff gauge and can display instantaneously true average velocity and also has a rain-proof digital computer read out. It is most useful for measuring flows in streams, rivers, canals, storm waters, wastewaters and industrial process waters.
To operate this digital flow meter, its flow probe incorporates the unique turbo-prop propeller sensor which makes it possible for positive displacement techniques to sense velocity and is designed to shed debris and has ample protection inside the two inch diameter housing. One can place the probe housing directly on the bottom of the pipes or streambeds in order to measure low flows down to two inch depths and the flow motor propeller turns feely on the shaft without mechanical interconnections and so has almost no friction.
In addition, the flow probe handle is able to telescope from three feet to six feet in height or five feet to fifteen feet and is made of anodized aluminum for its low weight as well as durability and can be extended up to twenty-five feet in length with the help of PVC pipe and extension cables, which allow sewer flow measurements from the level of the street and measuring of stream flows from the bridge. Attached to the lower section of the digital water flow meter is a three feet Mylar coated staff gauge which is graduated in hundredths of a foot and centimeters and this helps in instant water depth measurements as well as accurate positioning of the propeller.

What is the velocity in meters per second? And what is the radius?
What is the velocity of a beam of electrons that go undeflected when passing through perpendicular electric and magnetic fields of magnitude 7.0 103 V/m and 3.1 10-3 T, respectively?
What is the radius of the electron orbit if the electric field is turned off?
See, due to electric field electrons get accelerated and their speed increses.So after time t, v = {(eE)/m}t. At this instant when electric field is switched off, with this speed e move in strictly circular path with fixed radius. radius=mv/qB.
