Overview

A throttling device is a type of flow device in which a fluid filled with a pipeline flows through the pipeline. The flow beam will form a local contraction at the throttling point, thereby increasing the flow velocity and reducing the static pressure, resulting in a static pressure difference (or throttling flowmeter) before and after the throttling element.

Product Details

LGSeries flow measurement throttling device

Overview

LGThe series flow measurement throttling device is a primary device of differential pressure flowmeter, which is matched with differential pressure gauge or differential pressure transmitter and display instrument to form a differential pressure flowmeter. It has the advantages of simple structure, easy installation and maintenance, stable performance, and high accuracy. Our company produces standard throttling devices that comply with national standards GB/T2624.1-4-2006 and ISO5167-1-4-2003. It includes a transfer pressure standard orifice plate, ISA1932 nozzle, flange pressure standard orifice plate, radial distance pressure standard orifice plate, long diameter nozzle, and Venturi tube. In addition, according to the different needs of users, we also produce commonly used special throttling devices, such as 1/4 circular orifice plates, double orifice plates, eccentric orifice plates, circular orifice plates, conical inlet orifice plates, end orifice plates, double Venturi tubes, etc.
