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. The pressure loss of the Venturi nozzle is relatively small, and its length is shorter than that of the Venturi tube.

Take pressure at the corner joint.

Mainly used for gas flow measurement with large caliber, low static pressure, and short distance from on-site support pipelines.
