Product details

The standard orifice plate is a thin plate with circular holes, concentric with the pipe, and the edge of the right angle entrance is very sharp.

Standard orifice plate is a primary device in differential pressure flow measurement system. It can be used with differential pressure transmitter to measure the flow rate of liquid, gas and steam.

It is widely applied in petroleum, chemical industry, metallurgy, electric power, light industry, paper making, pharmaceutical and other departments.


▲Orifice plate flow meter has simple structure, firm, stable and reliable performance, long service life and low price.

▲Executive standard:ASME ISO-5167.

▲It is widely applied, all single-phase flow can be measured, some miscible flow can also be applied.

▲It can be used without real flow calibration.

Technical Parameters:

▲PN : ≤ 32MPa.

▲DN: 15 ~ 1000mm .

▲Material: Stainless Steel;

                   Alloy Steel;

                   Monel & Inconel;

                   Duplex Stainless Steel;

                   Other Material available on application.

▲Working Temperature: According to the demands of customers.

▲Accuracy (uncertainty) :1%.

▲Connection: Angle Pressure-taking, flange and Radial pressure-taking.

Install Requirement :

1. The fluid must be Newtonian fluid, that is, it is uniform in physics and thermodynamics, single-phase, or can be considered to be single-phase.

2. The center of orifice plate, flange center, pipe center and gasket shall be concentric, and the degree of difference shall not exceed 0.002d/beta.

3. The positive and negative pressure direction of the orifice plate, and the upstream and downstream pressure taking flange shall conform to the flow direction of the medium.

4. Make sure the tube is filled with liquid.

5. Fluid flow does not change with time or varies very slowly.
