Connection types clamp, G internal thread, G external thread or flange clamp. Pressure resistance \u003cstrong\u003e16 bar\u003c\/strong\u003e, medium temperature \u003cstrong\u003e-40 … +120 °C\u003c\/strong\u003e, +140 °C optional, ambient -25 … +85 °C. A protection grade is not documented. A declaration of conformity is not documented in the data sheet. Before sizing, note: No protection grade is given in the sheet; it has to be requested. Accuracy and reproducibility refer to the range; at a tenth of the range, 0.5 % of range is 5 % of reading. The parameter table gives DN4 … DN25, the tables and the order code DN4 … DN50; the flange clamp exists only up to DN25.\u003c\/p\u003e\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eCompact design for small quantities\u003c\/li\u003e\u003cli\u003ePEEK measuring tube, Hastelloy C electrode\u003c\/li\u003e\u003cli\u003eClamp, thread or flange clamp\u003c\/li\u003e\u003cli\u003eResponse time below 100 ms\u003c\/li\u003e\u003cli\u003ePulse, 4 … 20 mA and RS485\u003c\/li\u003e\u003cli\u003eColour display in the round head with instantaneous flow and total\u003c\/li\u003e\u003cli\u003eSetting by three keys M, + and −\u003c\/li\u003e\u003cli\u003eReverse-polarity and short-circuit protected\u003c\/li\u003e\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453662568774,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QMKD_produkt.webp?v=1790331873","url":"https:\/\/octogon-sensors.com\/en\/products\/qmkd-compact-electromagnetic-flowmeter-peek-tube","provider":"octogon GmbH","version":"1.0","type":"link"}
