KARAT-523 is the water meter employs the highly accurate ultrasonic technology. Every drop is measured due to the dynamic range of 250:1 reducing loss. Contrary to mechanical water meters Karat-523 has no moving parts, is magnet-resistant and maintains its pinpoint accuracy throughout its entire lifetime.
KARAT-523 is comes with option of being read remotely using LoRaWAN or M-Bus. KARAT -523 is equipped by communication module that allows for safe and easy remote reading without any add-on devices.
Water meter is made of eco-friendly and durable materials approved for drinking water.
