Why would you think it wouldn't? The operation of a magmeter is not dependent on the acidity/alkalinity of the fluid, unless it's likely to be corroded in extreme cases.

Can you answer these questions:

Magmeter Selection

The key questions which need to be answered before selecting a magnetic flowmeter are:

•

Is the fluid conductive or water based?

•

Is the fluid or slurry abrasive?

•

Do you require an integral display or remote display?

•

Do you require an analog output?

•

What is the minimum and maximum flow rate for the flow meter?

•

What is the minimum and maximum process pressure?

•

What is the minimum and maximum process temperature?

•

Is the fluid chemically compatible with the flow meter wetted parts?

•

What is the size of the pipe?

•

Is the pipe always full?

Try a google search to find more info on magmeters.

pH=7, like potable water? Oh, how dull.

I wondered if the OP thought that neutral pH meant that the fluid couldn't carry a charge...i.e. was neutral in an electrical sense.

Hmmmmm cool water.....lovely

Yes. As long as the Conductivity is greater than 5 ųS/cm.
