Misuratore di calore ad ultrasuoni

il misuratore di calore ad ultrasuoni combina il sensore di flusso ad ultrasuoni e le doppie sonde di temperatura PT100 per calcolare l'energia di riscaldamento/raffreddamento. Si adatta a DN15-6000 tubi, supporta tipi multi-trasduttore, con registrazione dati e comunicazione RS485 per la misurazione dell'energia HVAC.
