Colour display with instantaneous flow, totalized volume and raw frequency, three keys.\u003c\/p\u003e\u003cp\u003eHousing of stainless steel (grade not named), display housing of stainless steel or engineering plastic, seal FKM. Pressure \u003cstrong\u003e400 bar\u003c\/strong\u003e. Medium temperature -30 … +120 °C, +140 °C with field T of the order code. Plate mounting with two sealing grooves; the 350 L\/min size has a SAE 1¼ inch 6000 PSI flange face. The protection grade is not documented. A declaration of conformity is not documented in the datasheet. Before sizing, note: the supply is given as 16 … 30 V DC in the data block and 12 … 30 V DC in the wiring diagram; design for 16 … 30 V DC until clarified. Without a stated K-factor the pulse output cannot be scaled. The mounting plate is drawn for only four of the seven ranges.\u003c\/p\u003e\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\u003cul\u003e\u003cli\u003ePlate mounting without straight inlet run\u003c\/li\u003e\u003cli\u003ePressure up to 400 bar\u003c\/li\u003e\u003cli\u003eSeven ranges from 50 mL\/min to 350 L\/min\u003c\/li\u003e\u003cli\u003eRepeatability ± 0.2 % of full scale\u003c\/li\u003e\u003cli\u003eOutputs 4 … 20 mA, PNP\/NPN, pulse, RS485 or IO-Link\u003c\/li\u003e\u003cli\u003eTemperature output in version SA\u003c\/li\u003e\u003cli\u003eColour display with totalizer and frequency page\u003c\/li\u003e\u003cli\u003eAccuracy stated as unaffected by pressure and flow changes\u003c\/li\u003e\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453640909126,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QZKB_produkt.webp?v=1790331901","url":"https:\/\/octogon-sensors.com\/en\/products\/qzkb-plate-mounted-gear-flowmeter","provider":"octogon GmbH","version":"1.0","type":"link"}
