Re: [Phys-l] Electromagnetic flow meter ?

Just occurred to me. W/out Googling, didn't Drs. use a similar method to
measure blood flow before ultra sound doppler?


Yes, the conductive sensors are in contact with water, there are in an
horizontal plane.B vector is in vertical plane.
The direction of the electromotive force is based on Fleming's right-hand

As a first, cheap shot, are your conductive sensors on the INSIDE of the
tube - in electrical contact with the fluid? Also, check the direction of
the B field.
