1. What does air flow meter mean?
Air flow meter; Example sentence: 1. Unclip the hot film mass air flow meter cable. Release the cable of the hot film mass air flow meter. 2. Reconnect the hot film mass air flow meter. Reconnect the hot film mass air flow meter.
2. May I ask which brand and specification of peak flow meter (for monitoring respiration) to choose? Nowadays, there is no comparison between mechanical and electronic methods. Electronic testing has more lung function values, more accurate numbers, and can be used in conjunction with software to automatically record numbers for a long time. It can also record asthma diaries. No need for additional items, convenient, convenient, fast, and domestically produced Piko-1 approved by the National Food and Drug Administration is priced at less than 300 yuan (available on Taobao). Imported Piko-1 is too expensive, costing over 600 yuan, but the functions are the same. I also saw it for sale on the Amazon website and it has already been exported to the United States. There are various names for peak velocity meters, some of which are called peak flow meters, peak velocity meters, or peak expiratory flow meters. The English name is Peak Flow Meter. Search for the above names yourself and compare the prices. I also bought one, priced at 279 yuan on Taobao. Its good to use and much more convenient than the mechanical ones I used to use. Its much easier than the ones I used to use in the past, and I can still measure PEF and FEV1 values three times a day (which was not possible for those who used mechanical ones in the past). The domestically produced ones I know include Shanghai Keka (produced by Shanghai Wanbo), Ningbo Ningyin, and the so-called import
3. What is a mass flow meter
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 differen
