I am urgently looking for either new or second hand Masoneilan 12300 Liquid Level Transmitter Head.
I have a serious problem on the plant and Masoneilan said the item is now obsolete.
Even circuit boards in immaculate condition will help.
I haven't seen those for ages, perhaps a transmitter from another manufacturer will fit the same bridle.
I did a search for "Displacer Type Level Transmitter" and came up with Magnetrol, Mobrey, Clark-Reliance, Kobold.
Sad part is there must be hundreds gathering dust, perhaps get in touch with a long time vendor and make it worth their while to search around old customer database.
