عدادات التدفق

يستخدم المشترون كتابتين للجزء نفسه من الموزع وكلتاهما صحيحة: عدّاد تدفق الوقود ومقياس تدفق الوقود قطعة واحدة، وهي الحجرة التي تحوّل التدفق إلى كمية قابلة للفوترة. وكل عداد نصنعه يعمل بالمبدأ نفسه القائم على عدّاد الإزاحة الموجبة، ويُكتب أيضاً مقياس الإزاحة الموجبة: حجرة قياس بحجم معروف تدور مع التدفق، فتبقى الدقة ثابتة عند تغيّر اللزوجة أو الحرارة.

Two families cover the work. The DTJ range is the dispenser range — DTJ3, DTJ4 in three inlet sizes, DTJ6 from 5 to 160 L/min and DTJ100 for compact cabinets — sized to drop into an existing dispenser. The M-Series is the industrial range for bulk transfer, truck loading and depot metering, and it is the family quoted with a choice of register. A mechanical flow meter uses a dial register and needs no external power, which suits a tanker or a depot line. An electronic flow meter replaces the dial with an ARM-based counter and an LCD, adding free or preset delivery and an optional ticket printer; because that readout is digital, the same configuration also appears in searches as a digital flow meter. All three configurations share the same meter body and the same accuracy and pressure ratings.

As a flowmeter manufacturer we build the chamber, the register and the calibration bench, so the figure on the nameplate is measured here rather than inherited from a supplier. That covers a standard diesel flowmeter position, a fuel dispenser flow meter for high-flow cabinets and the lpg flowmeter line for liquefied gas. Each dispenser-grade model is a high accuracy flow meter at ±0.2% across its working range, with the LPG line quoted at ±0.5%.

One question decides most flow meter for fuel dispenser projects: does the meter drive a mechanical counter, or a controller that counts pulses and therefore needs pulses per litre fixed against a K-factor? Answer that and the model follows. Tell us the media, the flow range and the dispenser brand, and we will match the meter within 24 hours.
