Marine Oil Water Monitoring Devices, Water Alarm

The BilgMon488 bilge alarm has been designed specifically for use in conjunction with 15 ppm oil-water separator units. BilgMon488 performance meets the requirements of  the International Maritime Organisation specifications for 15 ppm bilge alarms contained  in
resolution MEPC. 107(49). 
BilgMon488 bilge alarm is equipped with 2 adjustable alarms that are triggered when the oil-content  of the processed sample exceeds the set limit (1 - 15 ppm, works-adjusted to 15ppm). Alarm outputs consist of relays and indicator LEDs. Additionally a 0(4) - 20 mA current
output signal (corresponding to 0 - 30 ppm) is available to enable remote surveillance  and recording of oil contents.
