May I ask which brand and specification of peak current 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 imported Bairui (also a product of Wanbo). Imported products include IML (from the United States), and what other Asthma checks are available. These are all mechanical. The above products are priced between 100 yuan and 200 yuan. Domestic electronic peak velocimeters include Dr. Michaels PF200 (MicroLife), while imported ones include Piko-1. I am using PF200, which is half cheaper than imported ones and costs over 600 yuan. The functions are the same, and it also comes with a two-year warranty.

2. Why does the smart flowmeter display a negative value of 23.85 during operation?

Xuner Instrument answers for you: The reason for the negative flow value is:

1. The sensor is not installed according to the flow direction label, causing the measurement direction to be opposite.

2、 The sensor signal line is reversed. Due to the forward and reverse flow measurement function of the intelligent electromagnetic flowmeter, the reverse flow is displayed. Solution: Swap the signal line.

3、 Measure if the pipeline is empty or not filled with gas. At this point, the flow meter will display negative numbers or fluctuating flow values. Solution: Fill the pipeline with the measured medium to enable the flowmeter to have measurement conditions. For detailed information, please refer to: flow-meter.com.cn
