Types of Electrodos

If you are asking what types of materials exist for electrodes the list is quite long..

316L Stainless Steel

Hastelloy C22

Hastelloy C276

Platinum

Titanium

Tantalum

etc.

As far as class if you are asking for ratings you can find class 1 or class 2 ratings..

We are not sure what you mean by, " Which have insertion length?" If you can restate your question we would be happy to have another go at an answer..

Cheers,

You don't need an insertion length, Captain. The electrodes can be flush with the pipe walls.

Indeed sir! The majority of Mag flow sensors have electrodes that are flush with the tube liners. The reason is to protect the electrode and to not provide a hang up point for any foreign matter in the pipe.
