      Electromagnetic BTU Flow Meter

      FM-28
      FM-28-R

      Features:
      BTU Cal FM- meter is the latest addition to the Fed rel series for accurate thermal energy measurement. It utilizes a high-accuracy electromagnetic flowmeter to measure the flow volume of the chilled water; hot water or condensed water, and two matched temperature sensors to measure the supply and return temperature. FM- Fedrel provides abundant input-output and communication options which make it easy to be integrated into any meter reading system, PLC or BMS system.

      Salient:

      • High accuracy, billing grade. Up to 0.5% accuracy for fow, 0.15°F (0.08°C) for the temperature difference
      • Plug and play. All parameters are pre-configured in the factory
      • Integrated BTU measurement system. Single source responsibility
      • Bi-directional
      • Short straight-pipe run, thus, suitable for any desired installation location
      • No moving parts to wear and tear. Save maintenance cost
      • Standard output 4-20mA, pulse, dry contact (relay)
      • Optional MODBUS, HART

      Applications:
      The FM- 28 are high-performance BTU meter accuratel{measures the thermal energy consumption or transportation of a heating/cooling system. It is an ideal choice for a wide range of applications in HVAC, heating/cooling energy production, energy transfer, building management, facility management, district heating and cooling, geothermal or solar hot water system monitoring, and more.
