Tehnoloogia jaoks mõõtmine anemomeetrid ja a viis tegemiseks tegemiseks a otsus!
The measurement range of flow velocity from {{{0}} to 100m/s can be divided into three sections: low speed: 0 to 5m/s; Medium speed: 5 to 40m/s; High speed: 40 to 100m/s. Termiline tundlik sond of anemomeetri/anemomeeter kasutatakse mõõtmiseks vahemik alates 0 5m/s; Pöörlev sond of anemomeetri/anemomeetril on kõige ideaalsel efektil vahemikul 5 kuni 40m/s; Ja kasutamine a pitot toru saab saavutada parim tulemused in the the high-speed range. An täienda standard for selecting the flow rate sond of an anemometer/anemometer õigesti is temperatuur, mis tavaliselt kasutatakse temperatuuril ligikaudu pluss {-70}C for termilised andurid of anemometers/anemometers. Rootor sond of a spetsiaalselt projekteeritud anemomeeter/anemomeeter can reach 350C. Pitot torud kasutatakse temperatuurid üle pluss 350C.
The working principle of the thermal sensitive probe of the anemometer/anemometer is based on the cold impact airflow taking away the heat on the thermal element. With the help of a regulating switch, the temperature is kept constant, and the regulating current is proportional to the flow rate. When using a thermosensitive probe in turbulence, airflow from all directions simultaneously impacts the thermal element, which can affect the accuracy of the measurement results. When measuring in turbulence, the reading of the thermal anemometer/anemometer velocity sensor is often higher than that of the rotary probe. The above phenomena can be observed during pipeline measurement. According to different designs for managing pipeline turbulence, it can even occur at low speeds. Therefore, the anemometer/anemometer measurement process should be carried out on the straight section of the pipeline. The starting point of the straight section should be at least 10 times before the measurement point × D (D=pipeline diameter, in CM); The endpoint should be at least 4 after the measurement point × Location D. The fluid cross-section must not have any obstruction. (edges, overhangs, objects, etc.)
Ratas tüüp sond jaoks anemomeeter/anemomeeter
The working principle of the rotary sond of the anemometer/anemometer is based on converting the rotation into an electrical signal. First, through a proximity sensor start, the rotation of the rotary wheel is "counted" and a pulse series is genereeritud. Siis, after being converted by the detector, the speed value can be geted. suur läbimõõt sond (60 mm - 2c 100 mm) of an anemometer/anemomeeter on sobiv mõõtmiseks turbulents keskmine ja väike voolukiirus (näiteks at torujuhtme väljalaskeavad). väike kaliiber sond an anemomeeter 2fanemomeetri jaoks on rohkem sobiv mõõtmiseks õhuvool koos a ristlõige pindala suurem kui 100 korda see uurimine pea.
