Medium temperature -20 … +80 °C, ambient temperature -20 … +50 °C. The protection grade is not documented. Explosion protection per datasheet Ex ib IIB T4; certificate, notified body and ATEX or IECEx number are not documented. A declaration of conformity is not documented in the datasheet. Before sizing, note: the order code offers eight pressure ratings from 1.6 to 42 MPa, the size tables give only 1.6 MPa for every size. DN32, DN40, DN65 and DN125 exist in stainless steel only, DN200, DN250 and DN300 in aluminium only. Supply voltage, wiring diagram and pin assignment are missing.\u003c\/p\u003e\n\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTurbine principle for gas, 2.5 … 6500 m³\/h\u003c\/li\u003e\n\u003cli\u003eNominal sizes DN25 … DN300 with flange connection\u003c\/li\u003e\n\u003cli\u003eAccuracy class 1.5 with non-linear correction\u003c\/li\u003e\n\u003cli\u003eTemperature and pressure compensation in the head as an option\u003c\/li\u003e\n\u003cli\u003eLCD display for flow, total, temperature and pressure\u003c\/li\u003e\n\u003cli\u003eOutputs 4 … 20 mA, pulse and RS485\u003c\/li\u003e\n\u003cli\u003eInstrument factor set on site by key\u003c\/li\u003e\n\u003cli\u003eBody of aluminium alloy or stainless steel\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453620756806,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QGKA_produkt.webp?v=1790331840","url":"https:\/\/octogon-sensors.com\/en\/products\/qgka-gas-turbine-flowmeter-flanged","provider":"octogon GmbH","version":"1.0","type":"link"}
