1. What is a mass flow meter: A mass flow meter, abbreviated as MFM, is a precision sensor used to quickly and accurately measure the flow rate of process gases.
. The mass flowmeter mentioned here is mainly used for low pressure, low flow single or mixed gases, with low pressure generally below 1Mpa and a maximum of 3Mpa; The flow range is generally 0.1 sccm to 5000 slpm; Single gases such as common air, helium, argon, etc. require relative dryness and purity; For mixed gases, it is necessary to specify the type and proportion of gases. 2. What parameters can be obtained from a mass flow meter? The Yidu mass flow meter can accurately obtain five major parameters of gas: real-time temperature, pressure, operating flow rate, standard flow rate, and cumulative flow rate. The units of a mass flow meter are generally SLPM (liters per minute under standard conditions) and SCCM (milliliters per minute under standard conditions), both of which are volumetric flow units under standard conditions. The measurement scale is defined as 101.325KPa and 25 ℃. The composition of a mass flow meter: The Yidu laminar flow mass flow meter mainly consists of six parts: laminar flow components, pressure differential sensors, pressure sensors, temperature sensors, circuit design, and software algorithms. The working principle of a 5-layer laminar pressure differential mass flowmeter: The laminar pressure differential principle is designed based on the Hagenbauer law. When the temperature, pipe diameter, and other parameters are constant, the gas is in a laminar state. By obtaining the pressure differential signal at both ends of the laminar flow element, the volumetric flow rate is calculated, and then the standard volumetric flow rate is obtained by correcting the temperature, pressure, and other parameters. Schematic diagram of Yidu mass flowmeter structure: 6 Communication of mass flowmeter: Yidu mass flowmeter can switch media, define standard conditions, display parameters and other operations through digital signals such as RS4855, profibus, 0-5V, 4-20mA analog signals or touch screen display panel.
