Product Details

Orifice Plates Instrument Of Flow Meter Differential Pressure Orifice Plate Flowmeter

 

Product Description
In the pipeline full with fluid, a throttling elements orifice plate is installed. When the fluid flows, static pressure difference occurs on both upstream and downstream sides. By using differential pressure transmitter or gauge, the differential pressure value is converted into standard current signal or aero-pneumatic signal to show the flow or volume of the fluid on the displaying instruments. orifice plate flow meter consists of the orifice plate pilot pressure piping and differential pressure gauge or transmitter.

Detailed Images

LG throttling gear is a primary device in a differential pressure flow measurement system, which consists of a throttle, a pressure-receiving device and a straight pipe section. Throttling device is divided into standard throttling device and non-standard throttling device, the one is coincident with IS05167 and GB/T2624 standard is the standard throttling device, the others are non-standard throttling deivce.
When the pipe filled fluid flows through the throttling device in the pipe, according to the law of conservation of energy and the equation of flow continuity, the stream will form a local contraction at the throttle, thereby increasing the flow rate, static pressure reduction, static pressure difference ΔP(or named differential pressure) before and after the throttle. The greater the flow rate of the fluid, the greater the differential pressure generated before and after the throttle, and the amount of fluid flow is measured by measuring the differential pressure before and after the throttle.
Standard throttling devices should normally be used whenever possible, and non-standard throttling devices can be used only when the fluid Reynolds number is small or contains impurities.
