Application Of Oil-water Interface Sensor In Oil-water Separation Equipment

- Jan 04, 2021-

The principle of oil-water interface sensor:

The photoelectric oil-water interface sensor uses the difference in electrical conductivity of oil and water media. The light is at the interface of the two different media, so that the reflected light intensity received by the light receiving transistor inside the sensor is different, which corresponds to two different switching states. . The oil-water interface sensor can detect the height of the oil-water interface and output related signals to achieve the purpose of detecting the height of the oil-water interface.

Application of oil-water interface sensor:

1. In the joint station, the oil-water interface sensor can be used to easily understand the changes of the free water interface and how to control the opening of the valve; in the oil transfer station, the oil-water interface sensor can clearly understand the changes of the three-in-one liquid level, Know how to control the displacement of the pump.

2. At present, the traditional liquid level of the storage tank adopts the detection ruler to measure the oil and the magnetic flap level gauge, but these two methods cannot detect the oil-water interface of the storage tank, only the total height of the liquid level can be detected, and it cannot be remotely transmitted; The oil-water interface sensor can distinguish oil, water and air.

3. In the refrigeration system, compressors, accumulators, circulating barrels, and other containers can be used to detect the key points, upper and lower limit points or multi-point liquid level with oil-water interface sensors. Accurate and reliable measurement and monitoring, display alarms, and fixed-point control And the oil tank level of heavy machinery and railway equipment, whether the pipeline is full of liquid, etc.

Advantages of oil-water interface sensor:

The oil-water separation sensor does not require manual intervention, is automatically calibrated, has no temperature drift, and is not affected by changes in the medium. That means the same sensor, regardless of whether the detected medium is water, gasoline or diesel, and no matter how the temperature changes, the oil-water separation sensor outputs accurate liquid level height signals completely and correctly.

The oil-water separation sensor can display the oil level, water level, temperature, and oil volume of the tank at the gas station, and can output alarm signals at the same time, support data query on the mobile phone, and realize digital management of gas stations, tank trucks, and oil-water separation equipment.
