Base prover volume (65036+)
Holds the base volume of the prover barrel as determined by the water-draw
method, in the units specified by Prover size units (register 65018.L). This
parameter is meaningful only for non-master meter provers.
The accepted standards mandate that the base volume of a bidirectional prover
be that registered by a round trip of the displacer.
Flow tube inside diameter (mm) (65038+)
This parameter is the measured inside diameter of the prover barrel at standard
(base) conditions and is meaningful only for non-master meter provers with the
option Prover is double-walled (register 65011 bit 5) clear.
Flow tube wall thickness (mm) (65040+)
This parameter is the measured thickness of the prover barrel wall, and is
meaningful only for non-master meter provers with the option Prover is double-
walled (register 65011 bit 5) clear.
Flow tube modulus of elasticity (65042+)
This parameter is the prover barrel material modulus of elasticity, and is
meaningful only for non-master meter provers with the option Prover is double-
walled (register 65011 bit 5) clear. The default value is that of carbon steel,
206.8e+6 kPa or 30.00e+6 psi.
