The US6/US10 sensor is a level sensor that allows a height measurement (the air draft) without contact with the liquid. The US6 sensor has a full scale of 6m, while the US10 sensor has a full scale of 10m.
This sensor is not designed to be in contact with the effluent to be measured. Indeed, although it is IP68 certified, prolonged immersion may affect its performance. Specifically, temporary immersion in clear water poses a moderate risk to the product, but immersion in dirty water, sewage water, or dirty stream water can seriously damage the product.
The US6/US10 ultrasonic sensor can be integrated into all installations where level is measured.
In particular, it can be used to :
Two main criteria are taken into account when choosing a level sensor: the budget and the environmental constraints of the sensor (effluent to be measured, type of liquid, etc.).
It also depends on the individual: some customers, who could quite easily use a piezometer sensorSome customers, who could use an ultrasonic sensor, prefer to use an ultrasonic sensor for reasons of convenience and uniformity of their measuring equipment.
The ultrasonic sensor is not installed in the same way as a underwater sensor It is above the level to be measured. It has different constraints: ultrasonic technology can transmit a signal conducted in air (some ultrasonic technologies can also transmit a frequency in water, like Doppler technologies).
Thus, ultrasound will measure a distance via the transmission of an ultrasound frequency through air; it cannot therefore work in the case of a vacuum.
Several of our products can be used to measure levels in an airless space: the sensors radar are particularly suitable (unlike ultrasonic sensors, piezometric sensors are immersed and measure the height of water above them).
The ultrasonic sensor works by transmitting a frequency through the air, so any variation in the air can affect the measurement.
The first variation that can influence the measurement is the temperature. The air temperature affects the scattering of the ultrasonic frequency, which can lead to measurement errors, which is why our US6/US10 sensors are equipped with temperature compensation. However, it is important that the body of the ultrasonic sensor is not exposed to direct sunlight to prevent it from heating up. If the sensor is exposed to the sun, a significant temperature shift may occur during the day: the air temperature may vary rapidly but the sensor temperature will remain very high due to its thermal inertia (it forms a compact mass), which will create a measurement error.
Ultrasonic technology is also sensitive to wind: air movements will disturb the transmission of the ultrasonic signal, causing errors in the measurement. Humidity can also be a problem: water droplets in rain, fog, mist or water vapour can also interfere with the ultrasound signal.

The competitive advantage of US6 or US10 is its ease of implementation. Objectively, this product is very easy to implement as it only requires two parameters to be entered:
The US6/US10 sensor is easily set up with The USP (its parameterisation box). Once these elements have been set up, the sensor is simply connected to the system and can be used directly.
Most brands sell sensors that require setting the 0 value (which requires emptying the tank or effluent to be measured) and the maximum (which requires filling the area to be measured). This method is much more tedious.
