The YFLJ integrated orifice flow meter is a high-range ratio 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), and an integrated orifice The board device is simpler, no pressure pipe is needed, the structure is compact, and the installation is convenient. It can measure the flow of gas, steam, liquid and natural gas, and is widely used in process control and measurement in the fields of petroleum, chemical industry, metallurgy, electric power, heating, and water supply.
● Compact structure and easy installation
● Good pressure resistance, good flange sealing performance
●No pressure tube is needed, the detected differential pressure signal is more reliable, and the measurement accuracy is higher
● There are various installation methods, flange clamping and flange integrated type are optional
● Pressure method: flange pressure; corner joint pressure, annular chamber pressure; travel pressure, etc.
