This document is a commissioning manual for the Model 6290 Tank Gauging System by Scientific Instruments, Inc. The system is used to monitor the level, temperature, and density of cryogenic liquid in a large storage tank. This manual provides detailed instructions for the normal start-up procedures and installation verification process.
The Model 6290 Tank Gauging System monitors the level, temperature, and density of cryogenic liquid in large storage tanks. This document covers the procedures to be followed before the equipment is put into regular use, assuming mechanical installation and field wiring have already been completed according to the Installation Manual.
The system monitors the level, temperature, and density of cryogenic liquid in a large storage tank.
The density signal period should be approximately 176 microseconds in air.
The LED labeled SCC-CPU should blink once per second.
