The purpose of this manual is to describe the installation, operation, and maintenance of the bubble-gage manometers currently (1982) used by the U.S. Geological Survey. Other applications of these devices, such as the long manometer and differential manometer, are discussed, and accessories available for them are described.
The bubble gage (water-stage manometer with gas-purge system) described in the Installation and Service Manual, October 1962, has been extensively modified and developed into the STACOM (stabilized and temperature compensated) device. This chapter is the manual for the STACOM unit and an update of the manual for the screw-type bubble gage. A parts list is included for both units.
