| Magnetic Flow Meter Assembly Azbil |
Magnetic flow meters, also called electromagnetic flow meters or "magmeters", operate on a very simple principal. An electrically conductive liquid moving through a magnetic field will generate a voltage that is related to the velocity of the liquid. Magnetic flow meters have no moving parts and present little to no pressure drop to the piping system into which they are installed. It is a flow-through device and does require the cross section of the pipe to be completely filled by the subject fluid in order to produce a useful reading.
Some characteristics of magnetic flow meters.
- Sensor assembly has no moving parts.
- The subject fluid must be electrically conductive.
- Measurement reflects fluid velocity and is not impacted by viscosity, density, or static pressure.
- Other than regular calibration and operational checkout, no maintenance requirements.
- Produces velocity reading only. Need other inputs to produce a mass flow value.
- Bidirectional flow measurement is possible.
- Little or no pressure drop associated with the instrument.
- Comparatively higher in weight.
- Accurate measurements require entire pipe cross section to be full of fluid.
