need advice on entering in this world.

to the world:


Sure, You should hire me as a consultant in the industry.

Look at
Endress Hauser
Polysonics
Fischer Porter

These are the better known ultrasonics around today, at least in the
US. You have a tough job. Dozens of ultrasonic companies have appeared
in the past few years and pricing has dropped. The good news is that
there are a lot of stupid mistakes that designer put into these
instruments. You should get someone who has had to make these things
work in the field.

Look at where the market is. Water and wastewater industries use lots
of these items. I would guess that the petrochemical industry also use
a lot.

Is your company producing ultrasonic Doppler flowmeters too or is it
just open channel and flow? Some companies are producing hybrid units
that measure flow in partially filled channels by both Doppler and
level. Customers seem to want these units. Polysonics seem to be held
as the best on the market right now but I see a lot of improvements
they could make.

Ask me some more specific info. Ultrasonic measurement systems has
been my company's biggest product to install and commission over the
years.
