Turbine Flowmeter pickup sensor
In most Turbine Flow Meters, magnets are fitted to the blades, and a magnetic pickup sensor is used to create the pulses.
The shape and the voltage level of the generated pulses depend entirely upon the type of pickup unit used.
The electrical pickup sensing device could be a simple 2-wire passive magnetic pickup producing an AC-type output.
The electrical pickup sensing device could be a 3-wire active device such as a Hall Effect sensor that produces cleaner and more uniform square wave pulses.
Watch the video and type down the correct answer in the comments below:
The higher the rate of flow, the faster the flowmeter rotor turns
a) and the higher the DC output voltage produced
b) and the greater the number of pulses produced
c) and the lower the number of pulses produced.

How does a Turbine Flowmeter Work?
Let’s talk about how a Turbine Flow Meter works.
A Turbine Flow Meter is inserted in a pipe directly in the flow path.
The mechanical part of the Turbine Flow Meter has a turbine rotor placed in the path of a flowing stream.
The only moving part of the Turbine Meter is the mechanical rotor. The rotational speed of the rotor depends upon the flow velocity. The rotor blades are usually made of stainless steel.
Watch the video and type down the correct answer in the comments below:
As the rotor spins in a turbine flowmeter, the passage of each rotor blade past a pickup point will generate
a) A varying DC voltage
b) A PWM signal
c) An electrical pulse

Turbine Flowmeter
In this video, we’re going to discuss a very common flow measuring device called a Turbine Flow Meter.
Depending on who you talk to, a Turbine Meter has one or two major parts. Some will tell you that the Turbine Meter has only one part – the Mechanical component.
Others will refer to a Turbine Meter as having 2 parts: The Mechanical component and the Electrical component.

Have you heard about VTR? The Versatile Test Reactor,will be a state-of-the-art science and technology lab for advanced nuclear energy in the U.S. and will feature a sodium-cooled fast reactor that uses high energy neutrons to test and develop advanced reactor fuels and materials.
.
Fast reactors use fast-moving neutrons to operate at higher temperatures and lower pressures. They can be cooled by molten salt, liquid metal, or helium gas. This leads to inherent safety features, higher operating efficiencies and less waste.
.
Research conducted with VTR will be pivotal in creating new fuels, materials, instrumentation and sensors as well as developing methods to drastically extend lifetime reactor cores, boost fuel performance and even accelerate fusion research.
