Searching for Thermal mass flow meter, with stainless steel sheath, output preferably I2C

Hi. I'm having some serious trouble finding a Thermal mass flow meter, which will not be destroyed by occasional condensed water droplets in the measured gas. Yes, I'm aware that condensed water will make the output value invalid, but that is not an issue in my experiment.
Sage Metering sells Thermal mass flow meters, but only as complete applications (incl. RS-485, displays, etc.).
I only wish to buy the "tip" of the application, with stainless steel sheath (or similar) on the 2 sensors, and digital output: I2C.
To make sure you understand what I'm searching for, I have attached a drawing of such a "tip".
Does such a component exist?
Do you know where to search?

I designed a couple of their mass flow products for Kurz Instruments. Maybe they'd sell you a sensor. Otherwise I know of no sensor only sellers. Make your own? It's not very hard to do.

You wrote: "I designed a couple of their mass flow products for Kurz Instruments".
Did you design Sage Metering mass flow products for Kurz Instruments? Or did you design Kurz Instruments mass flow products?
 
Thanks a lot for your response, itsmoked!
1) Were the sensors you encountered very similar to the one shown on the drawing I uploaded with the original post. For example: Did they have the same overall design as in the picture? Were all parts of the sensors covered with a stainless steel sheath? What was the shape of the sensors (Crosssection: Rectangular or circular)? And how wide were they: Ø6, Ø8, Ø10mm?
2) Did you work include designing the very tip (the part shown on the uploaded picture)? Or did you work on all of the other tasks: RS-485, display, power etc.?
3) Does your reply mean that Kurz also develops the tip of the sensor, or do they buy it from a supplier?
