Model EL4501 Flow Computer with Multifunction Temperature Compensator
Brand: Oval CorporationUsing the most advanced electronic technologies, this digital instrument has been developed specifically to meet the most demanding flow measurement applications in petroleum products receiving facilities 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- Incorporated capabilities to calibrate meter error for viscosity and flow velocity (viscosity correction), to correct by volumetric conversion factor (temperature correction), and to display the total flow readings readily permit the application engineer to build a petroleum products measurement system with this single instrument
- Changing the meter factor, ranges of temperature, 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 totals, can be reviewed on command with the front panel keypad, whether or not calculation is in progress.
