STEP #2
| Mag Meters: Are They Right For My Application? |
| 1. The first step in determining whether
a Mag meter is the correct flow solution for your problem is to determine the conductivity
of your media. Typically, mag meters work well in applications where the liquids are
electrically conductive. If your liquid is non-conductive you may want to consider another
solution. |
2. Next, it is required to have a full pipe at the area
of measurement. If this is a new installation then a full pipe can be guaranteed by
the piping installation. If not then 99% of all mag meters require a full pipe the
only option available now would be the New Tidalflux which
actually takes a level measurement first then calculates a flow rate through a partially
full pipe. |
| 3. Next, the media needs to be
examined for its potential to coat the electrodes of the mag meter. This should be
fairly obvious if the media has a viscosity similar to chocolate or glue then coating can
be a problem and effect the functionality of the mag meter. If your media has the
potential to coat the inside of your pipe and please email or call us for a case by case
evaluation. Krohne's new Capaflux uses non-contacting
electrodes which eliminate the potential for coating and should be considered if other mag
meters have failed in the past. |
4. If all the earlier criteria are met then the final
consideration is the material compatibility of the mag meter. Typically, a
mag meter has two (2) areas to be concerned about the liner and the electrodes.
Rarely does the outside of the meter itself come in contact with the media. A
material compatibility chart can tell you if the media you are measuring is compatible
with the electrodes (Hastelloy C is standard) and the liner (teflon typically).
However, other materials are available of request. For detailed specifications of
the materials please see the Mag Meter specification pages! |
The next step is to understand the components of a Krohne Mag flow
solution.
