The prover pressure correction factors will be based on the reference calibration pressure. The modulus of
elasticity combined with the live pressure are used to calculate wall expansion due to pressure.

After the second detector switch is tripped. The Flow Computer allows for certain delay period
proportional to time between prover run first and second detector switch. To allow for the prove ball to
stabilize, after the time expires, the launch sequence will be re-initiated.

If the prove run was not achieved in the set time, then the prove will be aborted. The reason for this
function is to accommodate the possibility the second detector switch was not triggered for one reason or
another, or the proving was launched from the wrong direction.

The prover temperature should be stable before proving. This would indicate that the prover and the fluid
through the prover have similar temperatures. The sample period configured is a command to the Flow
Computer to sample the prover temperature every so many minutes and compares the temperature to the
previous sample.
