Series

 VTY20

 Highlights

 •Low wear and extremely long durability due to high quality bearing

 •Practically no deviation in mass production due to fixed pulse rate, wide measuring span (up to 1:60),

 •High measuring accuracy, mostly independent of fitting position due to integrated flow straightener
