Variable-Area Flow Meter na may Alarm Switch for Immediate Abnormality Feedback.

Ang variable-area flow meter na may mga switch ng alarm ay isang setup kung saan ang alarm sa ibabaw ng BJ01 at BJ02 lower limit alarm switch. ay idinagdag sa mga mayroon nang sukat ng flow meter sa mga guide rails. Ang mga switch ng alarm ay maaaring signal sa anumang halaga ng flow, maging ito ay maximum, intermediate, o minimum. Kapag ang magnetic float ay umabot o lumampas sa posisyon ng switch, ito ay gumagamit ng bistable magnetic action ng isang tambo switch, na nagbibigay-daan sa flow meter at ang magnetic float upang buksan at isinara ang mga contact. Ang mekanismo na ito ay ginagamit kasama ang mga bahagi ng relay at iba pang mga elemento upang matugunan ang mga kinakailangan para sa mga pandinig at visual alarms.

Mga applications at Functions

Upper Limit Alarm: Kapag ang magnetic float ay eksakto sa posisyon ng switch set, sarado ang contact. Kapag ang magnetic float ay nasa itaas ng posisyon ng switch set, ang contact ay nananatiling sarado. Kapag ang magnetic float ay nasa ibaba ng posisyon ng switch set, bubukas ang contact.
Lower Limit Alarm: Kapag ang magnetic float ay eksakto sa posisyon ng switch set, sarado ang contact. Kapag ang magnetic float ay nasa ibaba ng posisyon ng switch set, ang contact ay nananatiling sarado. Kapag ang magnetic float ay nasa itaas ng posisyon ng switch set, bubukas ang contact.
