Model EL4131 Flow Computer
Brand: Oval CorporationUsing the most advanced electronic technologies, this digital instrument has been developed specifically to meet the most demanding liquid flow measurement applications where accuracy is the prime requirement. In response to the liquid flowrate and temperature information arriving from the sensing terminal, such as a flowmeter, it totalizes the flow while implementing meter error and temperature corrections. An Analog output and instant flowrate (corrected for meter error and temperature) output are additional provisions.
Features- Changing the meter factor, ranges of temperature, pressure, or other parameters, of the companion flowmeter is simple by keystrokes on the front-panel keypad, or by inserting an IC card into the slot
- Built around a microprocessor, the instrument carries out calculations entirely in digital signal processing circuits to achieve a high degree of accuracy and reliability
- Variables, such as temperature and pressure, can be reviewed on command with the front panel keypad, whether or not calculation is in progress
- A nonvolatile memory (E2PROM) retains all parameters and variables. Variables are resettable following a power cycle or reset if so configured
