2. Magnetic flow meter - Wikipedia

   en.wikipedia.org/wiki/Magnetic_flow_meter

   A magnetic field is applied to the metering tube, which results in a potential difference proportional to the flow velocity perpendicular to the flux lines. The physical principle at work is electromagnetic induction. The magnetic flow meter requires a conducting fluid, for example, water that contains ions, and an electrical insulating pipe ...

4. Water metering - Wikipedia

   en.wikipedia.org/wiki/Water_metering

   A velocity-type meter measures the velocity of flow through a meter of known internal capacity. The speed of the flow can then be converted into a volume of flow to determine the usage. 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 ...

5. Computational magnetohydrodynamics - Wikipedia

   en.wikipedia.org/wiki/Computational_Magneto...

   The complexity mainly arises due to the presence of a magnetic field and its coupling with the fluid. One of the important issues is to numerically maintain the ∇ ⋅ B = 0 {\displaystyle \nabla \cdot {\mathbf {B} }=0} (conservation of magnetic flux ) condition, from Maxwell's equations , to avoid the presence of unrealistic effects, namely ...

6. Flow measurement - Wikipedia

   en.wikipedia.org/wiki/Flow_measurement

   Sonar flowmeters have the capacity of measuring the velocity of liquids or gases non-intrusively within the pipe and then leverage this velocity measurement into a flow rate by using the cross-sectional area of the pipe and the line pressure and temperature. The principle behind this flow measurement is the use of underwater acoustics.

8. Magnetohydrodynamic turbulence - Wikipedia

   en.wikipedia.org/wiki/Magnetohydrodynamic_Turbulence

   While the magnetic Reynolds number is the ratio of the nonlinear term and the diffusive term of the induction equation. In many practical situations, the Reynolds number of the flow is quite large. For such flows typically the velocity and the magnetic fields are random. Such flows are called to exhibit MHD turbulence.

9. Electromagnetic pump - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_pump

   The current is fed through a conducting liquid. Two permanent magnets are arranged to produce a magnetic field B ap as shown in the figure. The supplied current has a current density (J) and the magnetic field associated with this current can be called "Reaction magnetic Field (b rc)". The two magnetic fields B ap and b rc attempt to align with ...
