Flow meter
Integrated orifice plate flowmeter

Overview
是将标准孔板与多参数差压变送器(或差压变送器 、温度变送器及压力变送器 )配套组成的高量程比差压流量装置,可测量气体、蒸汽、液体及天然气的流量,广泛应用于石油、化工、冶金、电力、供热、供水等领域的过程控制和测量。 DXLG integrated orifice plate flowmeter is a high-range specific differential pressure flow device composed of a standard orifice plate and a multi-parameter differential pressure transmitter (or differential pressure transmitter , temperature transmitter and pressure transmitter ). Measure the flow of gas, steam, liquid and natural gas. It is widely used in process control and measurement in petroleum, chemical industry, metallurgy, electric power, heating, water supply and other fields.
Scope of application
1.Nominal diameter: 15 mm ≤DN≤1200mm
2. Nominal pressure: PN≤10MPa
3. Working temperature: -50 ℃ ≤t≤550 ℃
4. Range ratio: 1:10, 1:15
5. Accuracy: 0.5 level, 1 level
