No method of measuring chamber pressure is accurate. If you measure 100 rounds of exactly the same load, in exactly the same gun, with exactly the same test equipment using the crusher method the measurements will typically vary plus or minus 5% from round to round. Some rounds may be off from the average for that group by 10% or more.

The pressure of course must be low or the burners will be hard to light. Any change of pressure will also usually result in the flames dropping or being blown out. This gas machine can be constructed with water blower for about $25 or with the Root or Crowell blower for about $40.00, depending very much on the amount of piping that has to be done.

STRAIN, FORCE, PRESSURE, AND FLOW MEASUREMENTS 4.2 The dimensionless quantity ∆L/L is a measure of the force applied to the wire and is expressed in microstrains (1µε = 10–6 cm/cm) which is the same as parts-per-million (ppm). From this equation, note that larger gage factors result in proportionally
