Flow meter instrument direction

Hello !

i wanna know if for example a electromagnetic flow meter can measure flow in the two direction !
means we mount on pipe where the flow goes and back < >

The magnetic flowmeter can also be used for bidirectional flow measurement. It has the advantages of no pressure drop, linear output, short inlet/outlet pipe runs (five diameters upstream of the electrode plane and two diameters downstream), and good turndown.

Magnetic flowmeters are relatively expensive and are mainly limited to conductive fluid applications, such as acids, bases and slurries, as well as water. A pre-requisite for this type of flowmeter is that the fluid is electrically conductive with an absolute minimum conductivity of 2-5 ┬ÁSiemens.
