Series DMHF Heat Flow Meter



The Series DMHF adopt the MultiPulseTM Technology, Digital Signal Processing Technology and Error Correction Technology, which are the state-of-the-art non-invasive flow measurement technology, with a measuring system of very high accuracy, versatility, low cost of installation and ownership. The meter can calculate automatically caloric content of water under 0~200 temperatures, and can obtain instantaneous caloric value and totalized caloric value. The pipe range should be DN15-2500 (For series Insertion, the allowed pipe range is DN65-2500. For series Flanged, the allowed pipe range is DN20-2500.).




1. For transmitter, users can select fixed types or Portable types.
2. For transducer, non-invasive Clamp-on and Insertion type are available.

3. For temperature sensor, utilize Pt1000 with 0.1%, clamp-on and the Insertion type are available.
4. Internally configured batch controller makes batch control convenient and accurate.
5. No moving parts, no pressure drop, no need of maintenance.
6. Easy and economical installation, hot-tapped installation.
7. Daily, monthly and yearly totalized flow: totalized flow for the last 64 days and months as well as for the last 
5 years can be reviewed.

8. Optional SD card Data logger output, can memory Total heat flow, Heat flow rate, etc.
