Applications
Flats, Houses and Blocks
Meters energy in individual flats, single family and multi family houses, housing associations and blocks of flats, so heat and cooling are billed on actual use.
Small Industry
Suits small industrial installations where water carries the energy, up to a nominal flow of 15 m³/h.
Fast Installation
Basic configuration is set from the front keys on site, so one meter type can be stocked and set to suit each job, reducing stock and installation time.
Remote Meter Reading
A plug in module adds wired MBus, wireless MBus, BACnet, Modbus or analog output, so readings reach a Sycous data collection system and Mabdeck. See the Communication Modules section: CMi4140 LoRaWAN Module, NB-IoT Module, Wired MBus Module and Wireless MBus Module.
Fault Detection
Flags air in the flow sensor, wrong flow direction, flow above qs for more than an hour, and temperature sensor faults. See Information Codes.
