Na'urori masu auna firikwensin suna amfani da kayan PEEK da aka shigo da su a matsayin inlay, kuma ana amfani da tsarin allura guda ɗaya tare da PEEK inlay don tabbatar da ci gaba da amincin samar da samfurin.

Manufar samfurin THE PRODUCT PRINCIPLE

Electromagnetic flowmeter bisa ga Faraday electromagnetic induction doka, wanda ya nuna cewa mai gudanarwa motsi a cikin magnetic filin zai samar da induction ƙarfin lantarki. ruwaAna iya ganin a matsayin mai jagora; Magnetic filin da aka samar da wutar lantarki coil waje da tubing. Sensing ƙarfin lantarki amplitude kai tsaye daidai da motsi gudun da mai gudanarwa iri, bututun diamita da kuma magnetic filin ƙarfi, da darajar shi ne:
E=B*V*D*K
Tsarin:
E - induction ƙarfi;
B - ƙarfin magnetic induction;
V - motsi gudun conductive ruwa;
D - lantarki spacing; (auna ciki diamita na bututun)
K - coefficient dangane da magnetic filin rarraba da kuma axial tsawon (gauge coefficient);
daga cikinsu:
B, D da K na iya zama ƙimar da aka daidaita ko daidaitawa, don haka daidaito ya sauƙaƙa zuwa: E ∝ V.
Na'urar firikwensin ta sanya karfin E a matsayin siginar kwarara, ta aika zuwa mai juyawa, bayan sarrafa siginar da aka karfafa, ta canza tacewa da sauransu, ta nuna kwarara da tara kwarara ta hanyar ma'auni mai kwarara mai kwarara mai kwarara mai kwarara mai kwarara mai kwarara mai kwarara tare da bayan haske
