Using the most advanced electronic technologies, this digital instrument has been developed specifically for crude oil and heavy oil blend ratio measurement applications where accuracy is the prime requirement.
In response to the flowrate, temperature, and blend ratio information arriving from the OVAL flowmeter, it converts the flowrate to the equivalent volume flowrate under standard conitions and totalizes the flow.
An analog output and instant flowrate (corrected for meter error and temperature) output are additional provisions.
●Changing the meter factor, ranges of temperature and blend proportions, liquid kind, density, or other parameters, of the companion flowmeter is simple by keystrokes on the front-panel keypad.
●Built around a microprocessor, the instrument carries out calculations entirely in digital signal processing circuits to achieve high degree of accuracy and reliability.
●Variables such as temperature and pressure can be reviewed on command with the front panel keypad even during operation.
●A nonvolatile memory (E 2 PROM) retains all parameters and variables. Totalized value can be reset upon power depending on setting.
