hello... I am in charge of international sales and selling ultra sonic level meter. to be honest, I have no idea about this kind of products and just took over this job from my co-worker who ran away, left heavy duty for me.
Nowadays I am studying about level meter and sludge meter and open channel flow meter etc. but It is very hard to understand because my major was related to Media.
For beign successful sales person, what should I more study? and where can I get the information about ultra sonic measuring instrument?
Could you recommend the high-reputation exhibition of these instruments and trade web site?
I am looking forward to hearing kind advice from all around.
Thanks.
