It is a kind of volumetric flow measuring instrument, which is mainly used in oil, chemical, medical industries.
l Digital counter can be rotated at any angle in order to read the show value.
l It not only can display the accumulated flow rate, but also can display instant flow rate.
l It use two batteries (3.6v,5.4A) to supply power, whose service life is 8 years.
