In comparison with the previously offered instruments, substantial reduction in physical geometry, improved functions and ease of operation have been achieved. Included among the improvements in this newly developed instrument are simplified parameter changes and data logging with IC cards along with a large, easy-to-read LCD display.
This instrument receives density frequency signal from the density sensor and provides an analog output in proportion to the density of metered process fluid. In response to temperature and pressure signals, it also can provide an output corrected for reference conditions.
●Performs calculation of density corrected with temperature.
●Changing the ranges of density, temperature, pressure, or other parameters, of the companion densitometer is simple by keystrokes on the front-panel keypad or by inserting an IC card into the slot.
●A built-in CPU offers a high degree of performance and accuracy.
●Variables such as temperature, pressure, and density can be reviewed on command with the front panel keypad, whether or not computation is in progress.
●A nonvolatile memory (E2PROM) retains all parameters in the event of an ac power failure.
●If an error occurs, its nature is identified as an error message on the display.
