variable application restriction orifice plate
WLG is a kind of throttling device which possesses advantages of simple structure ,and good performance .The design ,manufacturing and applicationare all in conformity with the stipulations of international standards ISO5167-1991 or national standards GB/T2624-93.WLG orific-plate flowmeter can be used to measure volumetric flow of the stable one-orientation medium in the closed pipes coupled with differential pressure transmitter and relative flow display instrument .It is widely used in petroleum , chemical.metallurgy,power ,environment protection.
Characteristics
1.The construction is simple ,fastness and easy to install .
2.Pressure tapping mode : Angle joint or flange mode.
3.Needless of true flow calibration.
4. Widely used ,working reliably ,performing stably.
5.Various accessories can be designed for customers.

Main Features
1)With simple structure ,the flow meter is of high reliability without lining in the
measuring pipe .
2)The wide range of the nominal bore is suitable for all the pipe size between
DN2 and DN600.
3)Measurement is independent of fluid density ,viscosity ,humidity ,temperature
pressure and conductivity.
4)The sensor with advanced processing technology and liquid airproof is of long
natural life and of nice resistance to shaking leakage.It guarantees the instrument
good precision and stability .
Measurement is independent of fluid density ,viscosity ,humidity ,temperature ,
pressure and conductivity There are no obstacle parts in the measuring tube ,
no pressure loss to the tube of which the straight part is of low requirement.
The sensor with grounded electrode gurantees the grounding well.The sensor
with advanced processing technology is of nice resistance to the negative pressure .
