Ang SR41 ay isang variable area metal tube rotameter na bumabasang flow mula sa taas ng float sa loob ng tapered measuring tube, kaya gumagana ito sa local indication nang walang power supply. Kayang hawakan nito ang gas, liquid at steam mula 15 hanggang 150 mm sa Class 1.5 o Class 2.5 accuracy, na may turndown ratio na 20:1 at range na 2.5 hanggang 100000 L/h ng tubig o 0.07 hanggang 1000 cubic metres bawat oras ng hangin.
Kapag kailangan ng transmitted signal, ang meter ay maaaring paandarin ng 24 VDC o baterya at maglabas ng (4-20) mA na may HART, Modbus, FF o Profibus communication. Ang mga wetted parts ay available sa 304, 304L, 316, 316L, Hastelloy C, titanium o PTFE-lined stainless steel, ang housing ay IP67, at may float jamming self-diagnosis.
Paano naiiba ang SR41 sa differential pressure flowmeter?
Binabasa nito ang taas ng float sa tapered tube sa halip na pressure drop, kaya nagbibigay ito ng local indication nang walang kuryente at akma sa mababang flow sa maliliit na linya.
Anong accuracy ang aasahan ko?
May dalawang accuracy class na inaalok, Class 1.5 at Class 2.5, na may turndown ratio na 20:1 sa buong range.
Kailangan ba nito ng power supply?
Hindi para sa local indication; para sa transmitted signal, ang 24 VDC o baterya ay nagpapagana sa (4-20) mA output na may HART, Modbus, FF o Profibus.
Anong mga sukat ng tubo at flow ang sakop nito?
Ang nominal diameter range ay 15 hanggang 150 mm, sumasakop sa 2.5 hanggang 100000 L/h ng tubig o 0.07 hanggang 1000 cubic metres bawat oras ng hangin.
