Process connection female thread G1\/2 … G2 or M42 × 2. Medium temperature as technical parameter -30 … +80 °C, 150 °C on request. The protection grade is not documented. The flameproof version (order field E) has a cast housing with two cable entries; the sheet names no Ex marking. A declaration of conformity is not documented in the datasheet. Before sizing, note: the medium temperature is stated four different ways; only -30 … +80 °C is firm. The 20 … 200 L\/min size is printed with G1\/4, so its thread must be confirmed before ordering. Without a marking the flameproof version cannot be used in a hazardous area.\u003c\/p\u003e\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\u003cul\u003e\u003cli\u003ePositive displacement, no straight inlet run needed\u003c\/li\u003e\u003cli\u003eSix sizes up to 350 L\/min\u003c\/li\u003e\u003cli\u003eRepeatability ± 0.1 % of full scale\u003c\/li\u003e\u003cli\u003eSwitch, pulse and 4 … 20 mA output combined\u003c\/li\u003e\u003cli\u003eOLED display in version PAF\/NAF\u003c\/li\u003e\u003cli\u003eStainless steel body up to 400 bar\u003c\/li\u003e\u003cli\u003eFemale thread up to G2 or M42 × 2\u003c\/li\u003e\u003cli\u003ePTFE seal for corrosive media\u003c\/li\u003e\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453641302342,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QZKF_produkt.webp?v=1790331901","url":"https:\/\/octogon.org\/en\/products\/qzkf-gear-flowmeter-optional-oled-display","provider":"octogon GmbH","version":"1.0","type":"link"}
