Gear volume flow sensors HySense® QG
The gear volume flow sensors (HySense® QG) working via the displacement principle.

Gearwheels are set in motion via a medium. With each rotation of the gearwheels, a defined amount of liquid is transferred through the volume flow sensor. The rotation movements of the gearwheels are caught by signal pick-ups and transferred in digital impulses. HySense® QG gear volume flow sensors are available in different measurement ranges from 0,05 until 300,0 l/min.
