As with all MULTICAL® energy meters, MULTICAL® 303 employs the highly accurate ultrasonic technology. This means that it measures consumption down to the last drop – even at very low flows – which reduces the loss of distributed energy. Hence, MULTICAL® 303 provides building administrators with data they need for accurate consumption billing and optimizing the energy efficiency of buildings and distribution networks. MULTICAL® 303 comes with remote reading capabilities with customized datagrams and increased transmission power of 25 mW, which makes it possible to use the meter in a fixed network at a lower cost due to reduced number of concentrators. Its high protection class IP68 flow sensor makes the MULTICAL® 303 the leading and best-performing meter in its class.
The compact MULTICAL® 303 is designed to fit in anywhere, which makes it especially relevant for use in apartment buildings due to its small size and extreme versatility when it comes to installation. The flow sensor is very robust with respect to the turbulence that tends to occur in these installations due to the close proximity to valves, bends etc. Whether mounted horizontally, vertically or on walls, MULTICAL® 303 can be adjusted to perfectly fit its surroundings. Position, energy unit and much more can be configured on-site by means of a one-button system without any need for special tools or equipment.
