11Features • This product adopts an automatic operation method using sample water pressure which is matched to the operation of an oil separator or pump.• The automatic washing function of the detection unit can reduce troublesome manual washing work.• An error code indication provided at occurrence of a device fault and a stain indication of the detection unit facilitate maintenance and inspection. The product has a high-maintainability structure.• Operation records such as trouble alarms can be saved in a memory card and confirmed as required.• For alarms, a double safety method is used. When the oil concentration is 15 ppm or more, and When sample water is defective or the instrument is defective, a alarm is output.• Replacement of detecting part (sensor) separately sold can be accepted. as the completion of every five years' calibration.
Measuring methodThe FOCAS-1800 using a full optical continuous measuring method* can sure grasp changes of oil concentration every moment while providing a very quick measurement response.* The light coming form optical elements is received by multiple optical elements. Then, a complicated analysis about changes of oil type or concentration amd differences of pattern due to mixed foreign substances can be made by CPU and sofware in an instant through calculation.
FOCAS-1500c Bilge Alarm serves to continuously measure the concentration of oil in the bilge and other waste water produced on a ship. FOCAS-1500c meets the requirement of IMO Resolution MEPC60 (33) and has type-approval from JG, and DOT.Features
- It measures only the oil concentration, free from affection of detergent and suspended solid matter in the water.
- The production of air bubbles is inhibited to permit stabilized measurement.
- dual alarm system. An oil content alarm is given when the oil concentration exceeds 15ppm and a set alarm is given in the event of input (sample water) or instrument failure.
- "CHECK" button giving simple operation test.
- Installation and connection are carried out with ease because it is samll and right.
