Large-Diameter Heat Meters (DN50–DN300, Flanged)
Large-diameter heat meters are industrial-grade heat meters designed to measure the heat energy consumed in high-flow heating and cooling systems accurately and reliably. This category features flanged ultrasonic models from the Minol IUF (DN50–DN300) and Calmet PM02 (DN50–DN100) series. The models can be read remotely via wired M-Bus; for Minol Zenner IUF sets, the communication options depend on the calculator unit used. Filter the models by brand to compare prices, or request a quote for project purchases.
With large-diameter heat meters, the right choice depends on the system flow rate. Send us your design flow rate and pipe size, and we'll recommend the right DN size and model.
