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 mass flow signal and temperature/ density signals from the OVAL Coriolis flowmeter and, upon calucation, displays the total flow of solids content of pocess fluid that contains solids.
It also can display the corrected density for reference temperature and provide an analog output.
●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.
