Glossary

Ao

Effective area of the piston/cylinder at zero pressure and at the reference temperature.

Absolute

Pressure measurement referenced to absolute vacuum. See also Gauge.

Apparent Mass Reference Density

Density used to computer Apparent Mass values.

b1

Linear coefficient of elastic distortion.

b2

Quadratic coefficient of elastic distortion.

Buoyancy

An object submerged in a fluid is buoyed up by the fluid. The air surrounding the deadweight gauge masses reduces the downward force acting on the piston. The equilibrium pressure acting on the bottom of the piston is also less. The buoyant effect of "normal" air acting on stainless steel deadweight gauge masses reduces the

pressure by approximately 0.015% or 150 parts per million. See also Mass Apparent; Reference Density; and Density of Air.

c

Coefficient of thermal expansion.

Constant

Allows entry of a fixed value for the variable.

Cross Float

The calibration of one Deadweight Gauge against another Deadweight Gauge.

D

Reference dimension for the hanger mass.
