The LGB standard throttling device operates based on the Bernoulli principle and is combined with various differential pressure gauges, differential pressure transmitters, and flow integrators to form a flow meter for measuring volume or mass flow. It can be used in conjunction with regulating instruments and microcomputers to form a control system.

Corner pressure tapping: The corner pressure tapping standard orifice plate throttling device consists of a standard orifice plate and a ring chamber.
Flange pressure tapping: The upstream and downstream pressure tapping ports of the flange are 25.4mm away from the two end faces of the orifice plate.

Used for flow measurement in industries such as electricity, metallurgy, chemistry, and petroleum.
