الوصف
يَتحرّك عوامة مزوّدة بمغناطيس دائم بشكل موثوق على طول مستوى السائل على أنبوب دليل. داخل أنبوب الدليل يتم تركيب مفتاح قصبي (تلامس غاز خامل)، يتم تنشيطه عبر الجدران غير المغناطيسية للعوامة وأنبوب الدليل عند اقتراب مغناطيس العوامة. وباستخدام مغناطيس ومفتاح قصبي تكون عملية التحويل بدون تلامس، وخالية من التآكل ولا تتطلب إمدادًا بالطاقة. إن التلامسات خالية من الجهد. كما تتوفر مفاتيح العوامة أيضًا بنقاط تحويل متعددة.
تُشير وظائف التحويل دائمًا إلى ارتفاع مستوى السائل: تلامس عادةً مفتوح، أو عادةً مغلق، أو تلامس تحويل.

الشكل يسارًا: نسخة من الفولاذ المقاوم للصدأ، سنّ تركيب، الطراز FLS-S الشكل يمينًا: نسخة من البلاستيك، توصيل شَفْري، الطراز FLS-P
من خلال استخدام عوامة لحد أقصى 2 نقطة تحويل يمكن تحقيق سلوك مفتاح ثنائي الاستقرار، أي أن حالة التحويل تظل متاحة أيضًا عندما يستمر مستوى التعبئة في الارتفاع فوق نقطة التحويل أو الانخفاض تحتها.
مفتاح العوامة سهل التركيب وخالٍ من الصيانة، لذا تكون تكاليف التركيب والتشغيل والتكليف منخفضة.

الأسئلة والأجوبة
ما هو نطاق قياس المستوى لمفتاح التعويم FLS؟
يمتد نطاق القياس من 0 إلى 6000 mm حسب بيانات المنتج.
ما هي درجة حرارة التشغيل المسموحة؟
تعمل العوامة عند درجات حرارة تشغيل من -50 … +350 °C.
ما الحد الأقصى لضغط العملية؟
يعمل المفتاح عند ضغط يصل إلى 40 bar، ومن التفريغ (Vacuum) حتى هذا الحد.
ما الكثافة الحدية للوسيط؟
يجب ألا تقل كثافة الوسيط عن ρ ≥ 300 kg/m³ ليتمكن المفتاح من العمل بشكل صحيح.
ما توصيلات العملية المتوفرة؟
تتوفر توصيلات G 1 1/"، G 2" وحسب DIN DN 50 … DN 200 و ANSI 2" … 8".
هل تتوفر إصدارات مقاومة للانفجار؟
نعم، تتوفر نسخ Ex i II 1/2G Ex ia IIC T6 ... T1 Ga/Gb II 2D Ex ib IIIC T80°C ... T230°C Db و Ex d II 2G Ex d IIC T6 Gb II 2D Ex tb IIIC T80 °C Db.
ما درجة حماية الدخول؟
تصنيف الحماية هو IP66/IP68.
ما الذي يميز FLS عن حلول قياس المستوى الأخرى؟
بفضل استخدام مغناطيس دائم ومفتاح قصبي تكون عملية التحويل بدون تلامس، خالية من التآكل ولا تتطلب إمدادًا بالطاقة، كما يمكن تحقيق سلوك مفتاح ثنائي الاستقرار باستخدام عوامة لحد أقصى نقطتي تحويل، مع إمكانية تعدد نقاط التحويل. ---
