Calibration with air at 0 °C and 101.325 kPa.\u003c\/p\u003e\n\u003cp\u003eBody of stainless steel, aluminium alloy on request. Process connection MPT 1\", working pressure 0.8 MPa maximum. Medium temperature -10 … +65 °C, ambient temperature -25 … +85 °C, humidity 0 … 100 % RH. Protection grade IP40. Explosion protection is not documented. A declaration of conformity is not documented in the datasheet. Before sizing, note: several figures, among them flow range, maximum pressure and response time, are marked customizable or optional, no standard version is stated. The flow figures are standard litres at 0 °C, while the order code writes L\/min without a reference. For oxygen and hydrogen there is no statement on suitability or ignition protection.\u003c\/p\u003e\n\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDirect mass flow measurement without temperature or pressure compensation\u003c\/li\u003e\n\u003cli\u003eSolid-state sensor without membrane, resists clogging and pressure shock\u003c\/li\u003e\n\u003cli\u003eWithstands condensation, humidity 0 … 100 % RH\u003c\/li\u003e\n\u003cli\u003eResponse time 20 ms\u003c\/li\u003e\n\u003cli\u003eAnalogue 1 … 5 V or 4 … 20 mA, digital RS485 Modbus or I²C\u003c\/li\u003e\n\u003cli\u003eThread connection MPT 1\", stainless steel\u003c\/li\u003e\n\u003cli\u003eShock resistant up to 100 g\u003c\/li\u003e\n\u003cli\u003eM12 × 1 connector\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453627703622,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QGKI_produkt.webp?v=1790331873","url":"https:\/\/octogon-sensors.com\/en\/products\/qgki-mems-gas-mass-flowmeter-mpt-1","provider":"octogon GmbH","version":"1.0","type":"link"}
