OCMA-25 Automatic Oil Content Monitor

• Series OCMA-25

OCMA-25 Automatic Oil Content Monitor Over the past several decades, HORIBA has designed and manufactured a complete line of high-quality non-dispersing infrared analyzers and analyzer systems. HORIBA has extended infrared gas analyzer technology to the continuous measurement of oil in water for process monitoring and waste water alarm applications. The OCMA oil content analyzers are a unique solution to the problem of continuously and accurately measuring oil content in water; monitoring oil content in boiler water; monitoring process water for hydrocarbon break through; monitoring waste water discharge to meet regulatory requirements. Continuous monitoring meets water pollution control program. Features The OCMA-25 meets water pollution control program requirements. A rugged process-type instrument, the OCMA-25 provides a continuous real time measurement of the oil content in a sample stream. The OCMA-25 system is capable of measuring 0 ~ 5, 0 ~ 10, 0 ~ 20, up to 0~100 ppm full scale. The OCMA-25 provides digital display in concentration units, concentration alarm functions, and an isolated 4 ~ 20 mA DC output signal. No interference. Based on the principle of solvent extraction and infrared absorptiometry, the OCMA-25 is total-ly insensitive to interferences such as suspended solids, air bubbles, dissolved solids, etc. It is extremely accurate. 1.

Water separation filter Sensitive to all oils, the OCMA-25measures oil concentration as those substances which are extracted intofluorochlorocarbon S-316. They are measured at 3.4 microns, which is the major hydrocarbon NDIR absorption band. Both petroleum and vegetable oils may be measured. Fluorochlorocarbon S-316 solvent reclaimer reduces cost. An activated carbon solvent reclaimer is integrated into the OCMA-25 to continuously recover solvent used in the measurement. Fluorochlorocarbon S-316 solvent is recycled in the analyzer. This minimizes solvent loss, insuring less maintenance and less cost. Calibration and cleaning are automatic. The OCMA-25 reduces attended maintenance time. A built-in automatic calibration function for zero and span can be set to automatically reset and span the analyzer from once each hour to once each 24 hours. During the calibration, the sample inlet strainer is cleaned using compressed air supplied by an integral air pump. Six alarm functions are standard. The OCMA-25 is completely equipped with visible L.E.D. alarms. These alarms include: oil concentration alarm, out-of-calibration alarms, filter and solvent failure alarms. The oil concentration alarm is fully adjustable from 0 ~ 100% of full-scale. In addition to L.E.D. alarm indication, each alarm condition provides a contact closure rated at 0.5 AMP 110 volts.
