Micronics U1000MKII-HM | Ultraflo Clamp-on Heat/Energy Meter | 22–180 mm OD, EN1434
The Micronics Ultraflo U1000MKII-HM is a pipe-mounted clamp-on heat/energy meter for hot water up to 85 °C and chilled water, including water/glycol. It measures flow ultrasonically and flow and return temperatures with PT100 sensors, then displays energy rate and totalised energy calculated to comply with EN1434 section 6. Two adjustable pipe ranges cover 22–115 mm and 125–180 mm OD, and it serves energy management and billing in domestic, commercial, district or shared heating and cooling systems.
Key features
- Clamp-on alternative to in-line heat meters, with dry servicing
- Cross-correlation flow measurement with 1 MHz transducers for older, thick-walled pipes
- Pulse output for volume and energy in kWh (BTU)
- Optional Modbus RTU (RS485) and M-Bus for aM&T and BEMS
- Backlit LCD with installation and service information
- Installs by entering pipe ID, adjusting sensors and clamping on
