It is particularly suited to oils, fats, fuels, resins, adhesives, solvents, inks and refrigerants up to a viscosity of 10 000 Pa·s.\u003c\/p\u003e\u003cp\u003eTwo meshing gears displace a fixed volume per revolution, measuring range \u003cstrong\u003e5 mL\/min … 150 L\/min\u003c\/strong\u003e in seven sizes, accuracy \u003cstrong\u003e± 0.5 % of full scale\u003c\/strong\u003e, repeatability \u003cstrong\u003e± 0.2 % of full scale\u003c\/strong\u003e.

Colour display with flow, percentage of range and totalized volume, three keys.\u003c\/p\u003e\u003cp\u003eBody of aluminium (40 bar), stainless steel 304 or 316 (100 · 250 · 400 bar) or PP (10 bar); seal FKM up to 200 bar, PTFE above 200 bar or EPDM. Process connection G1\/4 … G1 by size, two mounting threads M5, M6 or M8. Medium temperature -30 … +120 °C, +140 °C with code T (not for aluminium and PP). The protection grade is not documented and the sheet names no CE mark. A declaration of conformity is not documented in the datasheet. Before sizing, note: the pressure statements disagree, and FKM stops at 200 bar although 250 and 400 bar bodies are offered. The accuracy refers to full scale, not to the reading. A filter finer than 100 mesh is required ahead of the meter.\u003c\/p\u003e\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\u003cul\u003e\u003cli\u003ePositive displacement, reading independent of density and viscosity\u003c\/li\u003e\u003cli\u003eSeven sizes from 5 mL\/min to 150 L\/min\u003c\/li\u003e\u003cli\u003eRepeatability ± 0.2 % of full scale\u003c\/li\u003e\u003cli\u003eOutputs 4 … 20 mA, PNP\/NPN, pulse, RS485, IO-Link\u003c\/li\u003e\u003cli\u003eColour display with totalizer and three keys\u003c\/li\u003e\u003cli\u003eStainless steel body up to 400 bar\u003c\/li\u003e\u003cli\u003eHigh-temperature option up to +140 °C\u003c\/li\u003e\u003cli\u003eTemperature output in version SA\u003c\/li\u003e\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453638910278,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QZKA_produkt.webp?v=1790331901","url":"https:\/\/octogon-sensors.com\/en\/products\/qzka-gear-flowmeter-with-colour-display","provider":"octogon GmbH","version":"1.0","type":"link"}
