A declaration of conformity is not documented in the data sheet. Before sizing, note: Parameter table and order code give different nominal size ranges; the sizes that can be delivered have to be settled with the enquiry. No temperature limit per lining is given; the order code knows only ≤ 70 °C and ≤ 120 °C. The pressure codes of the order code overlap.\u003c\/p\u003e\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eLow-conductivity version from 5 µS\/cm\u003c\/li\u003e\u003cli\u003eNo obstruction in the measuring tube\u003c\/li\u003e\u003cli\u003eTurndown 150:1\u003c\/li\u003e\u003cli\u003eForward and reverse flow, empty-pipe and flow limit alarms\u003c\/li\u003e\u003cli\u003eAccuracy classes documented across the velocity range\u003c\/li\u003e\u003cli\u003eBacklit LCD, rotatable up to 90°\u003c\/li\u003e\u003cli\u003eOne-piece or split version\u003c\/li\u003e\u003cli\u003eProtection grade IP65 or IP68\u003c\/li\u003e\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453662372166,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QMKC_produkt.webp?v=1790331873","url":"https:\/\/octogon-sensors.com\/en\/products\/qmkc-electromagnetic-flowmeter-low-conductivity","provider":"octogon GmbH","version":"1.0","type":"link"}
