Its PVDF construction provides excellent acid and alkali resistance, suitable for challenging liquids. It operates from DC 3.5–20 V, draws up to 15 mA, and outputs a clean pulse signal: high level \u0026gt; 4.5 V at 5 V input and low level \u0026lt; 0.5 V. Flow ranges are 1–30 L\/min for large holes and 0.5–8 L\/min for small holes, each within ±5% accuracy. Pulse rates are 258 pulses per liter for large holes and 780 pulses per liter for small holes, enabling straightforward flow calculation with microcontrollers or data loggers. The sensor is rated for humidity 35–90% RH (no frosting) and operates up to 80°C, with a G1\/2 thread for easy installation. Flow sensor model ZQ-01 is supplied without PCB, and the device carries multiple certifications for broad compatibility. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty. \u003c\/p\u003e \u003ch2\u003eBenefits \u0026amp; Tips\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eUse with microcontrollers or data loggers by counting output pulses to determine flow in real time.\u003c\/li\u003e\n\u003cli\u003eChoose large‑hole or small‑hole configuration based on your required flow range (1–30 L\/min or 0.5–8 L\/min) for best accuracy.\u003c\/li\u003e\n\u003cli\u003eInstall via G1\/2 threaded connection for quick integration into existing piping systems.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eProduct specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eModel: ZQ-01 (PVDF)\u003c\/li\u003e\n\u003cli\u003eMaterial: PVDF; Acid and alkali resistant; Corrosion-resistant\u003c\/li\u003e\n\u003cli\u003eType: Water flow sensor; G1\/2\u003c\/li\u003e\n\u003cli\u003eFlow range: 1–30 L\/min (large holes, ±5%); 0.5–8 L\/min (small holes, ±5%)\u003c\/li\u003e\n\u003cli\u003ePulse characteristics: Large hole ≈ 258 pulses per liter; Small hole ≈ 780 pulses per liter\u003c\/li\u003e\n\u003cli\u003eOutput: Pulse high \u0026gt; 4.5 V (at 5 V input); Pulse low \u0026lt; 0.5 V\u003c\/li\u003e\n\u003cli\u003eSupply voltage: DC 3.5–20 V\u003c\/li\u003e\n\u003cli\u003eMax current: 15 mA; Load: ≤ 10 mA (at 5 V)\u003c\/li\u003e\n\u003cli\u003eHumidity: 35%–90% RH (no frosting)\u003c\/li\u003e\n\u003cli\u003eOperating temperature: ≤ 80°C\u003c\/li\u003e\n\u003cli\u003eCertifications: CE, DOT, EAC, EPA, FCC, GMP, RoHS, TGA, UL, KC, PSE, WEEE\u003c\/li\u003e\n\u003cli\u003eOrigin: Mainland China\u003c\/li\u003e\n\u003cli\u003ePCB included: No\u003c\/li\u003e\n\u003cli\u003eBrand: NONE\u003c\/li\u003e\n\u003cli\u003eQuantity: 1\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003ePackage includes:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWater Flow Sensor x1\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eWarnings\/Reminders\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOperate within DC 3.5–20 V; at 5 V, expect output levels \u0026gt; 4.5 V (high) and \u0026lt; 0.5 V (low).\u003c\/li\u003e\n\u003cli\u003eFlow accuracy depends on hole size; calibrate in your application to ensure the correct flow readings.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eProviding quality and trusted service since 2002 at intercyprus.com\u003c\/p\u003e\n\u003c\/div\u003e","brand":"InterCyprus Trading Ltd","offers":[{"title":"1-30L per min","offer_id":54889355903318,"sku":"1005009988282948-1-30L per min","price":47.86,"currency_code":"EUR","in_stock":true},{"title":"0.5-8L per min","offer_id":54889355936086,"sku":"1005009988282948-0.5-8L per min","price":47.86,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0530\/0604\/1274\/files\/S024d9ac3df464c659c7eae7e251b9186X.webp?v=1785828630","url":"https:\/\/www.intercyprus.com\/products\/g1-2-water-flow-sensor-pvdf-material-hall-flowmeter-acid-and-alkali-resistant-corrosion-resistant-industrial-flow-rate-sensor","provider":"InterCyprus Trading Ltd","version":"1.0","type":"link"}
