Product Details
Sage Model 51 HVAC Series of Thermal Mass Flow Meters measures Natural Gas flow rate and consumption in commercial and municipal buildings, as well as college and university campuses, government facilities, hospitals, shopping centers and office buildings and complexes.
The HVAC Industry (Heating, Ventilation and Air Conditioning) provides processes, products, systems, and services that are aimed at heating, ventilating, and air conditioning buildings and facilities while maintaining thermal comfort, acceptable indoor air quality, and reasonable installation, operation, maintenance, and energy. Thus the need for accurate natural gas monitoring is critical, and the cost-effective Model 51 Thermal Mass
Flow Meter is the ideal measurement solution. The HVAC Series is available as an In-Line or Insertion style meter and provides a 4-20 mA analog output proportional to the NG flow rate, as well as pulsed outputs of totalized flow, and includes an easy to read display of flow rate, total, and temperature. In addition, BACnet communication is provided (or optional Modbus RTU) for communicating with energy dash-boards or other software Masters.
All Model 51 HVAC Thermal Mass Flow Meters are temperature-compensated and pressure insensitive, and are configured to provide a 100 to 1 turndown of natural gas with a Full Scale flow rate based on the pipe size specified. Over 165 samples are taken in the Sage NIST calibration facility to guarantee 1% of reading accuracy
