Shelok Hydraulic Orifice Flow Meter

Principle

As fluid flow full of a pipeline flow through the throttle device in the pipeline, the flow beam will be partially contracted in the throttle device so that the flow velocity increases, static pressure decreases, and then Static pressure difference will be formed in front and back of the throttle device. The greater the flow velocity of the fluid is, the greater the differential pressure increase, so the fluid flow can be measured by measuring the differential pressure of the throttle device.

 

孔板流量計

Introduction

Standard orifice can be applied to measure the flow of liquid, gas and steam in the pipeline. The Standard orifice was designed and manufactured according to the national standard GB/T2624-93 (ISO-5167), and tested according to the national standard JJG640-94. The Standard orifice can adopt three tap methods: corner taps (including annular chamber taps), flange taps or D-D / 2 taps.

The standard orifice is designed, manufactured and tested in accordance with national standards, it is not necessary to be calibrated in actual flow. The standard orifice is characterized as high precision, simple structure, low cost. But the loss of pressure in all the standard throttle devices was the most, so it is not suitable for the low pressure loss application. The Standard orifice can be widely applied to petroleum, chemical, metallurgy, electric power industries etc.
