It is particularly suited to clean, dry gases where the mass flow is to be measured directly without temperature or pressure compensation; it is calibrated for one gas chosen in the order code.\u003c\/p\u003e\n\u003cp\u003eThermal MEMS chip, the gas carries heat away from the sensor, which gives the mass flow directly.

Working pressure 0.5 MPa maximum, pressure loss at full scale 100 Pa (DN3) or 600 Pa (DN8). Operating temperature -10 … +55 °C, humidity below 95 % RH without icing or condensation. Body material, protection grade and explosion protection are not stated. A declaration of conformity is not documented in the datasheet. Before sizing, note: the 50 SLPM full scale is in the parameter table but has no order code. For oxygen and hydrogen there is no statement on suitability or ignition protection. Pin assignment and mating connector of the socket are not documented.\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\u003eTurndown 100:1\u003c\/li\u003e\n\u003cli\u003eRepeatability 0.25 %\u003c\/li\u003e\n\u003cli\u003eResponse time 10 ms, 20 … 1000 ms on request\u003c\/li\u003e\n\u003cli\u003eFour-digit LED display for instantaneous and totalized flow\u003c\/li\u003e\n\u003cli\u003eRS485 or RS232 plus analogue output 0.5 … 4.5 V\u003c\/li\u003e\n\u003cli\u003eHighest and lowest value since power-up recorded\u003c\/li\u003e\n\u003cli\u003eCalibration for one of seven gases selectable\u003c\/li\u003e\n\u003cli\u003eCompact, 55 … 77 g\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453624066374,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QGKC_produkt.webp?v=1790331840","url":"https:\/\/octogon-sensors.com\/en\/products\/qgkc-mems-gas-mass-flowmeter-led-display","provider":"octogon GmbH","version":"1.0","type":"link"}
