1. Radar flowmeter
2. Automatic control identification symbol of flowmeter
The automatic control identification symbol of flowmeter mainly follows national standards and P&ID graphic specifications, with the core identification being the letter "F" combined with functional suffixes. 1. National Standard Symbol Specification (GB/T 2625-2010) Flow meters start with the letter "F" in the instrument tag number, and use suffix letters to indicate specific functions: • FI: flow indicator (F represents Flow, I represents Indication) • FR: flow recorder (R represents Recording) • FC: flow controller (C represents Control) 3. What is a mass flow meter/mass flow controller?
Mass flow meters/mass flow controllers are high-precision flow control devices that have significant advantages in the fields of flow measurement and control. Mass flow meter, abbreviated as MFM, is a specialized instrument for accurately measuring the volumetric flow rate of gases. Its measurement results are not affected by changes in ambient temperature and pressure, and are mainly used in gas flow testing, calibration, and leak detection applications. And the mass flow controller, MFC， In addition to the function of a quality sparrow wild flow meter, it is also equipped with a precision electromagnetic proportional control valve, which has flow control capability. MFC is commonly used for the integration of flow control modules in high-end manufacturing equipment, as well as accurate gas distribution in scientific research experiments. Its design considers the needs of online monitoring and remote control. In terms of units, mass flow meters and controllers are usually measured in SCCM (milliliters per minute under standard condit

Comparison of performance and application of laminar flow principle and thermal principle gas mass flow meters/controllers (1) Gas microflow measurement and control is one of the important core technologies in high-end manufacturing, and its core sensors and control components are gas mass flow meters and gas mass flow controllers.
. These devices are mainly used for accurate measurement and control of small and micro flow (from 0.000001m ³/hour to 300m ³/hour, corresponding to pipe diameters ranging from 3mm to 65mm) gases. They require small volume, meticulous measurement and control, and can withstand the influence of environmental temperature and pressure as well as different gas working media. At present, there are two main principles of gas mass flow meters and controllers that meet these requireme
