Flow meters are a type of sensor. Flow meters are used for measuring the volume, direction, and mass of the liquid and other gases present. Flow meters measure the flow in the pipe. Flow meters are a type of instrument.A rotameter measures the flow rate of a gas or a liquid. It comprises a measuring scale, float, and a tube. A low flow rate rotameter detects a minimum/low flow rate in a liquid/gas.
The integral meter is a flow element can be close -coupled with differential pressure transmitters to make a complete flow meter. It provides easy-to-install, low-cost measurement of the small flows found frequently in plant metering operations and research projects.Integral Flow Orifice Assembly is used when Differential Pressure transmitters must be directly mounted on the orifice assembly. This eliminates the cost of installation of differential Pressure Transmitter with impulse piping up to the orifice assembly.The YFLJP integrated orifice flowmeter 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. The orifice meter can be easily maintained. Measures a wide range of flows. They have a simple construction. They have easily fitted between the flanges.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.Overall uncertainty of an orifice meter, including the effects of the secondary instrumentation, can be as low as 0.6%. With in-situ calibration, the orifice meter can achieve an accuracy of about +/- 0.25%. An orifice flow meter in liquid flow application can achieve precise flow rate measurement.The relevant standards are BS 1042 and the equivalent ISO 5167. One of the principle advantages of orifice plates manufactured and installed following these standards is that they do not require calibration. This means that orifice plates are very cost effective on larger line sizes.
● 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.
