Oil analyzer AE-2

watertemperaturefor integration

Petroleum hydrocarbons analyzer AE-2 is designed for continuous automatic monitoring of content of petroleum hydrocarbons in potable, natural, and waste water. The instrument comprises a sample preparation unit and a fluorescence detector. The sample preparation unit provides metered water feed and switching of the water and reagent flows, control of temperature, mixing and mass-exchange processes. The detector (or optical cell) performs the detection of fluorescence of petroleum hydrocarbons extracted by hexane from the sample using a patented chromato membrane technology. The analyzer is installed stationary and is controlled using a built-in microprocessor or an external PC. In a stand-alone operating mode, the selected reaction sequence can be assigned from a built-in keyboard. A firmware allows assigning any sequence of operation of system components and altering the flow rates from 0.02 to 20 ml/min. The instruments are equipped with a 4-20-mA current loop and RS485 computer interface for customized report output and remote computer control. Concentration measurement results, up to 1000 values, are stored in a built-in memory and are displayed, in milligrams per liter, on a built-in digital LC display. If concentration of petroleum hydrocarbons exceeds a threshold level, the alarm mode is activated and a relay may be triggered following a command from the analyzer. Typical measurement cycle duration is 5 - 15 min (depending on concentration of the analyzed sample) principle of operation Is based on the measurement of fluorescence intensity that is proportional to the concentration of the TPH. features and benefits Continuous on-line monitoring;
