Water flow measuring

Hello,

I need your help to choose new order number for these devices:

1. Flow measuring:

SITRANS F M Intermag 2/Transmag 2 Magnetic-inductive Flow Transmitters 7ME5033, 7ME5034

7ME5033 0AA11 1AA0 (old one)

2. Sensor for measuring (which is connected to flow measurer)

7ME5002-1AB00-0AA0

My problem is that they are out of order. So can you tell me how to choose the appropriate order number, especially for the measuring sensor. I have asked Siemens, they told that they are out of production.

So does anybody know to choose the new one.

Thank you.
