Abstract: The Deadweight Gauge Is the most accurate Instrument available for the measurement of pressures. Repeatable readings with accuracies of O.IX to .02% of measured pressure are obtainable. The device does not require recalibration unless the components have excessive wear or weights are replaced. It is easily transported and set up in the field, requires minimum maintenance, and is simple to operate. Tripod mounting Is available for most i nstruments. With the addition of a pressure pump, valves, and pressure connections, the hydraulic Deadweight Gauge becomes a Deadweight Tester and can be used to alibrate pressure transducers and other, less-accurate pressure gauges. The pneumatic deadweight instruments are testers since they deliver air at an accurate pressure using an unregulated supply.
