Item: 'Endurance' regulator with pressure & flow gauges
Date of manufacture: 1940s ?
Manufacturer: BOC
Description: This 'Endurance' regulator is identical to the cutaway example but has been prepared as an oxygen therapy regulator. It is equipped with both a cylinder contents (Bourdon) gauge (0 - 3000 psi) and and a fixed orifice flowmeter (0 - 12 L/min.) utilising a Bourdon gauge.The latter is located downstream of the needle valve seat. The pressure developed across the restrictor for any given flow depends upon the density of the gas. In this case it is calibrated for oxygen.
