 "summary": "The InnovaSonic 207i is a clamp-on ultrasonic liquid flow meter that can also calculate thermal energy. With its BACnet MS/TP module it exposes 23 Analog Inputs (flow, velocity, flow and energy totals, temperatures, pressure, density, enthalpy, signal diagnostics and two error-flag words) and one Analog Value to reset the totalizers.",

  "Object names are the Object Name property values from the table; several differ from the row labels (for example AI-7 \"+ Energy Tot\").",
  "Flow, total, pressure and density units follow the units chosen in the meter menu. No read/write column is printed; only AV-1 is described as writable."
