Abstract

The problem described in this paper consisted of the development of an integrating gas or mass flowmeter, pressure and temperature compensated to ±5 percent in mass or gas flow and whose readings are transmitted by wiring to an indicator located at a distance. The following general requirements applied to the flowmeter problem:
  1. 1)

    Maximum flow rate of hydrogen gas—approximately 150 cubic feet per hour (355 grams per hour)

     
  2. 2)

    Entering gas temperature —(+50°C to -65°C)

     
  3. 3)

    Ambient pressure—2 to 15 psia

     
  4. 4)

    Meter to be integrating or totalizing

     
  5. 5)

    Meter not to be affected to any large degree by tilting or by the normal vibration encountered in transportation.
