 "summary": "The FT1 is an insertion or inline thermal mass flow meter for gases. With the RS485 option set to BACnet MS/TP it acts as a BACnet Smart Sensor with four Analog Inputs: flow, gas temperature, flow total and elapsed time since the total was reset.",

  "The manual lists the objects as plain text (Analog Input 1 = Flow and so on) without units or access; all four are listed read-only here and units follow the meter's display settings.",
  "The ONICON F-5500 thermal mass flow sensor manual (DOC-0005059) prints the identical four objects; that meter reports ONICON's vendor ID 206 instead of Fox Thermal's 650.",
  "The AI 3 label \"Total Flow / Reset Total\" suggests the total can be reset, but the manual does not say how to do it over BACnet; the front-panel reset is described."
