Intelligent oil-in-water monitor

The oil-in-water monitor is specially designed for use with oil-water separation equipment. It is designed based on industrial instrument technology and 15ppm oil-in-water monitoring equipment. Its performance exceeds the 15ppm bilge alarm requirement of the International Maritime Organization resolution MEPC.107(49).

The device has two adjustable alarm points, factory set at 10ppm. Other alarm points (e.g., 100ppm) can be adjusted using the panel buttons on site.

If the measured value exceeds the alarm point, the indicator light on the panel will illuminate and the relevant relay will activate.

If the instrument malfunctions, the LED system on the panel will change from a flashing green light to a permanent red light, and the system fault relay will activate. The device has a 0(4)-20mA signal output for driving a recorder or external instrument.

1) This monitor must be installed and operated according to the operating manual to avoid unsafe situations.

2) The components mentioned in the operating instructions are not necessarily provided with the instrument at the time of sale, and the instrument may be equipped with other components.

3) Installation and maintenance must be performed by qualified personnel.

4) This monitor must be properly grounded.

5) Power must be turned off before performing any maintenance work.

6) If applicable, installation and maintenance should prioritize compliance with national or local regulations, followed by the instructions in this manual.

7) In freezing environments, the water in the measuring cell must be completely drained.

The oil-in-water analyzer monitor should be installed as close as possible to the sampling point to minimize response delay.

During installation, the oil-in-water monitor should be vertical to the horizontal plane, with the display at eye level. Sufficient space should be reserved on all sides for maintenance.

Avoid deformation of the casing or damage to the instrument during piping.

Ensure that airflow is unobstructed to the measuring cell. Parts on the measuring cell may heat up when the sample temperature is high. If the sample temperature is expected to be high, apply warning labels and take protective measures – do not touch hot parts to avoid burns.

a. When oily water sample flows through the monitor, the measured oil content value will be displayed.

b. If the oil concentration exceeds the set point, alarm indicator 1 will illuminate after a selected time delay. Then the alarm indicator will remain illuminated and the connected alarm relay will activate. Similarly, alarm indicator 2 will illuminate, and the connected alarm relay will take appropriate shutdown action.
