_01

_02

_03

  Display parameters can switch freely, can display instantaneous      flow (Nm3/h), total flow(Nm3), medium temperature (℃)and            pressure (Kpa) at the same screen.

_05

     Lower power consumption, could use the battery powered and        connect the external power,too.

 

_07

                         Double flow sensor, enjoy excellent stability, high                             accuracy and anti-vibration performance

 

_09

2_01

 

  Can be divided into five sections for correction, this operation will    make measuring more accurate

 

2_03

   Precession vortex flow meter combines the swirl generator and swirl eliminator in the       flow sensor, which can reduce the pressure loss, realize wider flow measuring range,       upgrade measurement !
