1. How to read the parameters of an intelligent electromagnetic flowmeter? The key to reading the parameters of an intelligent electromagnetic flowmeter is to understand the key performance indicators on its specifications, grinding ear nameplate, or instruction manual. These directly determine whether it can operate accurately and stably under your working conditions. 1. Core performance parameters These parameters determine the basic measurement capability of the flowmeter. *Diameter (DN): It must be consistent with the diameter of the pipeline decorated with Anyu lead, commonly used examples include DN2

5, DN50, DN100, etc. *Measurement range: Refers to the upper and lower limits of flow that can be accurately measured by a flowmeter, usually measured in meters per hour. When selecting, ensure that the commonly used flow falls within 50% -80% of this range. *Accuracy level: Refers to the maximum allowable measurement error, such as 0.5 level, which means the error does not exceed ± 0.5% of the actual value. The smaller the value, the higher the accuracy. *Working pressure and temperature: refers to the medium pressure (MPa) and temperature (℃) that the flowmeter body can withstand. It must be higher than the actual maximum value of the on-site process. The material parameters related to the medium are the key to selection, and choosing the wrong one can lead to rapid corrosion and damage to the instrument. *Lining material: The lining material directly contacts the medium and is responsible for insulation and corrosion prevention. *Chloroprene rubber: used for general water and sewage, with good wear resistance. *Polyurethane rubber: Excellent wear resistance, suitable for slurry, coal slurry, etc. *Polytetr

afluoroethylene (PTFE): It has a wide range of chemical resistance and is suitable for various corrosive media such as strong acids and alkalis. *Electrode material: The electrode is used to detect signals and its material needs to be resistant to medium corrosion. *316L stainless steel: used for non corrosive or weakly corrosive media, such as tap water and domestic sewage. *Hastelloy C (HC): resistant to high temperatures and strong corrosion, suitable for oxidizing acids such as nitric acid and mixed acids. *Titanium (Ti): It has good corrosion resistance, especially suitable for chlorides (such as seawater and saltwater). *Tantalum (Ta): It has excellent corrosion resistance, second only to platinum, especially resistant to hydrochloric acid corrosion. Environmental and installation parameters ensure that the flowmeter can work normally in the specific installation environment. *Protection level (IPXX): Indicates the degree to which the enclosure is dustproof and waterproof. For example, IP65 can prevent water spray, IP67 can prevent short-term immersion, and IP68 can work underwater for a long time. Outdoor or underground installation requires at least IP65 rating. *Output signal: Typically, there are 4-20mA analog signals (representing flow rate) and pulse/frequency signals (cumulative flow rate). In addition, contemporary intelligent flow meters all blindly support digital protocols such as HART, Profibus, Modbus, etc. for remote setting and diagnosis. *Power requirements: It is necessary to clarify whether the power supply is 220V AC or 24V DC, which matches the available power supply on site. 4.
