The standard orifice plate

The advantages,

1. The standard throttle parts are fully used and are recognized by the international standards organization, which can be used without actual flow calibration.

2. The structure is easy to copy, simple, firm, stable and reliable, and low price;

3. Wide application, including all single-phase fluid (liquid, gas, steam), partial miscible flow;

4. Test pieces and differential pressure display instruments can be produced by different manufacturers, and they are produced with specialized scale.

Technical parameters

1. Nominal diameter: 15 mm is less than or equal to DN less than 3000mm 2 and nominal pressure: PN is less than 40MPa

3, working temperature: - 50 ℃ or less t 550 or less than 4 ℃, the range: 1 to 5, the accuracy of: 0.5 on the Richter scale, grade 1

3. Parameters required for selection

1. Diameter of pipe (pipe diameter * wall thickness); 2. Medium of orifice flowmeter measurement; 3. The working temperature of the tested medium; 4. Work pressure of the measured medium (maximum pressure, minimum pressure, normal pressure); 5. Work flow of the measured medium (maximum flow, minimum flow, normal flow); 6. Viscosity of the measured medium

Installation requirements

Throttling device installation and apply to the following section and relevant fittings: throttling upstream side the first of the second resistance and resistance, the throttle on the right side of the first resistance under parts, from the upstream throttling a second resistance between the first resistance to the downstream parts of section, and the differential signal line, etc.
