Multiple optical sensors measure the combination of light absorbed and scattered by oil droplets in the sample stream. The sensor signals are read by a microprocessor which uses sophisticated algorithms to determine the concentration of oil and solids in the stream. The oil concentration is displayed on an alphanumeric display. A microprocessor drives a 4-20 mA current loop output representing the oil concentration. Two volt-free alarms are driven when the oil concentration exceeds the set points. An Autoclean system is included to ensure the accuracy of the optical measuring system is maintained over extended periods of operation.
The microprocessor also measures various other parameters to determine the condition of the system to ensure that accuracy is maintained over time and various environmental conditions. A log of alarms and faults is stored on the system for maintenance purposes.
A contact closure and remote start-stop facility are included to enable sample conditioning when used as part of a system. Three optional parameters can be displayed; these are PH, conductivity and oxygen concentration. Remote monitoring is available via HART or Modbus. A menu-driven system allows the operator to set or display various conditions via the keypad. HART is a registered trademark of the HART Communication Foundation.
