Oil on Water Monitor Model IRmat
Description:
The Oil on Water Monitor Model IRmat is used for continuous monitoring of water surfaces and detects floating oil with high sensitivity.
Infrared scan:
- Organic substances such as fats and oils reflect infrared rays, water absorbs most of the infrared rays.
- So the reflected IR- radiation is used to reliably detect oil films on the water surface.
Application:
- The model IRmat is used to check that the water surface is free of oil.
- It enables the early detection of oil ingress and leaks.
- The aim is to prevent environmental and facility damage.
Installation:
- The sensor must be at a constant distance from the water surface.
- Fluctuations in the water level are compensated for by using pontoons or by ultrasonic distance detection.
- To realize bypass measurements, surface water is pumped into a bypass tank via a skimmer . The free outlet of the tank ensures a constant water level so that the measurement takes place under ideal conditions.


Detection of oils:
The device can detect both mineral oils and synthetic oils.
Emulsion detection:
The instrumnt is able to identify emulsions.
Non-contact measurement:
The measurement method is non-contact and has a high response sensitivity.
Factory calibration:
The device is factory calibrated and ready for use.
Large scanning surface:
The scanning surface is approximately 10 cm in diameter.
Long-term stability and low maintenance:
It offers high long-term stability and requires minimum maintenance.
No moving parts:
The device has no moving parts .
High Power IR- LEDs:
The service life of the IR- LEDs is extremely long.
Automatic self-diagnosis:
The device performs a permanent automatic self-diagnosis.
Model IRmat installation in open Channel / Basin

Fixed mounting
Fixed mounting is an uncomplicated method of installing the sensor. The sensor is installed using either a mounting frame or an articulated arm. Here it is crucial to ensure a constant water level. For optimum measurement results, the water level should not fluctuate by more than +/- 1 cm, optionally +/- 7.5 cm with ultrasonic water level compensation.
Pontoon mounting
Pontoon mounting offers a simple way of compensating for changes in the water level. The pontoons always position the sensor at a constant distance above the water surface.
This principle ensures reliable measurement regardless of fluctuations in the water level.
Mounting at bypass tank
In case the Sensor is mounted on a bypass tank, a floating skimmer is used to forward the surface water into the tank by using self-priming pump.
Any floating oil is fed into the bypass tank together with the water. The free outlet of the tank ensures a constant water level so that the sensor is always at the optimum distance from the water surface.
