Heat Meter/ Cooling Meter zelsius® C5 CMF

Electronic compact measuring capsule meter for heat and cold energy suitable for connection interfaces according to DIN EN ISO 4064-4 Optional interfaces: M-Bus, wireless M-Bus, LoRaWAN® and 3 inputs/outputs Nominal sizes: qp 0.6 /1.5 /2.5 m³/h

The new zelsius® C5-CMF with measuring capsule flow meter combines compactness with rugged construction. The calculator on the zelsius® C5-CMF is removable as standard with a cable length of approx. 1.2 m and provides a real practical advantage in tight spaces and  transfer stations with covers. A matching wall adapter with mounting hardware is included in the delivery.

The flow sensor on the zelsius® C5-CMF has electronic, non-reactive impeller scanning and has  metrological approval for horizontal and vertical installation (downpipe and riser) according to the current European Measuring Instruments Directive 2014/32 /EU (MID).

The zelsius® C5-CMF is ideally suited for continuous use during regular meter replacement as well as for installation in pre-equipped single-pipe connectors (EAS) in new measuring points thanks to the large selection of directly compatible and commercially available connection interfaces.

System components for remote meter reading, customer service and MID compliant accessories for the
direct installation of temperatures make the zelsius®C5-CMF an optimal solution for practical use.
