It is particularly suited to liquids and gases in industrial automation, machinery, cooling, fire protection and petrochemicals.\u003c\/p\u003e\u003cp\u003eA spring-loaded paddle sits in the through bore; the flow deflects it and a linkage operates a microswitch. Setting range fixed by the model, eight models from four bores with two paddles A and B each, from \u003cstrong\u003e4.2 … 18 L\/min\u003c\/strong\u003e to \u003cstrong\u003e25 … 111 L\/min\u003c\/strong\u003e, fine setting by a knob. Repeatability \u003cstrong\u003e± 2.5 % of the total range\u003c\/strong\u003e; an accuracy is not documented; hysteresis 2 … 7 L\/min by model, measured with water at 20 °C.

An Ex marking is not given in the datasheet. A declaration of conformity is not documented in the datasheet. Before sizing, note: Type of protection, temperature class and certificate are not documented, so explosion protection is not substantiated. An ambient temperature is not documented. Neither a thread size nor a gland is given for the cable entry.\u003c\/p\u003e\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eWetted parts and enclosure in stainless steel\u003c\/li\u003e\u003cli\u003ePressure rating 100 bar\u003c\/li\u003e\u003cli\u003eMedium temperature up to 250 °C\u003c\/li\u003e\u003cli\u003eProtection IP67\u003c\/li\u003e\u003cli\u003eRepeatability ± 2.5 % of the total range\u003c\/li\u003e\u003cli\u003eSwitching point set by a knob\u003c\/li\u003e\u003cli\u003eSPDT contact 250 V AC, 3 A\u003c\/li\u003e\u003cli\u003eLow pressure loss 0.08 bar\u003c\/li\u003e\u003cli\u003eFour mounting positions permitted\u003c\/li\u003e\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453620691270,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QSKQ_produkt.webp?v=1790331901","url":"https:\/\/octogon-sensors.com\/en\/products\/qskq-in-line-paddle-flow-switch-in-stainless-enclosure","provider":"octogon GmbH","version":"1.0","type":"link"}
