Based on the principle of vortex flow measurement, the sensor measures the volume flow using the fluid movements generated at the vortex body or the resulting pressure differences. Grundfos Direct Sensors™ are suitable for use in aggressive media as well as in drinking water, making them ideal for volume flow measurement and heat metering in solar thermal and heating systems. The digital VFD Grundfos Direct Sensors™ measure temperature and volume flow with a single measuring element and transmit the measured values directly via the RESOL-VBus® protocol. Grundfos Direct Sensors™ are suitable for use in aggressive media as well as in drinking water, making them ideal for volume flow measurement and heat metering in solar thermal and heating systems. VFD 1 - 12 l are designed for use in systems with low flow rates. VFD 2 - 40 l are used in systems with higher flow rates. Due to its fast response time, the VFD 2 - 40 l is particularly suitable for use in fresh water stations. RPS Grundfos Direct Sensors™ measure temperature and relative pressure with a single measuring element. They can therefore be used perfectly for leakage and overpressure monitoring. Grundfos Direct Sensors™ are suitable for use in aggressive media as well as in drinking water, making them ideal for use in solar thermal and heating systems. The digital RPD Grundfos Direct Sensors™ measure temperature and relative pressure with a single measuring element and transmit the measured values directly via the RESOL-VBus® protocol. They can therefore be used perfectly for leakage and overpressure monitoring. Grundfos Direct Sensors™ are suitable for use in aggressive media as well as in drinking water, making them ideal for use in solar thermal and heating systems.\u003c\/p\u003e","brand":"Resol GmbH","offers":[{"title":"VFS 1-12 l\/min (Analog)","offer_id":54273183875413,"sku":"13000020","price":187.49,"currency_code":"EUR","in_stock":true},{"title":"VFS 2-40 l\/min (Analog)","offer_id":54273183908181,"sku":"13000030","price":191.49,"currency_code":"EUR","in_stock":true},{"title":"RPS 0-10 bar (Analog)","offer_id":54273183940949,"sku":"13000040","price":75.49,"currency_code":"EUR","in_stock":true},{"title":"VFD 1-12 l\/min (Digital)","offer_id":54273183973717,"sku":"13000080","price":187.49,"currency_code":"EUR","in_stock":true},{"title":"RPD 0-10 bar (digital)","offer_id":54273184006485,"sku":"13000090","price":75.49,"currency_code":"EUR","in_stock":true},{"title":"VFD 2-40 l\/min (Digital)","offer_id":54273184039253,"sku":"13000100","price":191.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/1247\/2405\/files\/Grundfos_Direct_Sensors_445x445_006b2cc2-6e6c-4f89-ab1f-c5d5907cfc38.jpg?v=1782999387","url":"https:\/\/wohnungstechnik.de\/en\/products\/resol-grundfos-direct-sensor-vfs-1-12-l","provider":"Wohnungstechnik.de","version":"1.0","type":"link"}
