Ultrasonic distance/level sensors play an extremely important role in water engineering due to their non-contact, high precision, easy installation, and strong adaptability. They are mainly used for liquid level and flow measurement, and are one of the key technologies for ensuring water supply safety, optimizing water treatment processes, preventing floods and disasters, and achieving smart water management.

The advantages of ultrasonic distance/level sensors in water engineering:

1/ Non contact measurement: The probe does not come into contact with the measured medium, avoiding problems such as corrosion, scaling, and pollution, especially suitable for measuring sewage, corrosive liquids, and drinking water (to avoid pollution).

2/ Easy installation and maintenance: Especially for the top mounted level gauges and open channel flow meters, there is usually no need to empty the container or stop the water during installation, and the maintenance amount is relatively low.

3/ Wide applicability: It can be used for containers, water tanks, and open channels of various sizes, with a measurement range from tens of centimeters to tens of meters.

4/ No mechanical moving parts: high reliability and long lifespan.

High precision: Modern ultrasonic sensors can achieve millimeter level accuracy, meeting the requirements of water metering and process control.

5/ Digital output: Easy to connect to SCADA systems, PLCs, or RTUs for remote monitoring and automation control.

6/ Adapt to harsh environments: Many products have waterproof and dustproof enclosures, suitable for outdoor and underwater (submerged probe) environments.

Key points to note when using:

1/ Foam, steam, dust: These factors will seriously absorb or scatter sound waves, leading to measurement errors or failures. It is necessary to choose a suitable installation location or consider other principles of sensors (such as radar).

2/ Strong turbulence or surface fluctuations: can affect the stability of liquid level measurement and may require damping treatment or the selection of instruments with wave suppression algorithms.

3/ Temperature compensation: The speed of sound varies with temperature, and high-quality ultrasonic instruments are equipped with built-in temperature sensors for real-time compensation. All of our MIC metering ultrasonic level sensors are with temperature compensation.

4/ Installation position: Avoid obstacles such as mixers, escalators, and inlet pipes to ensure that the sound cone covers the effective measurement area. The installation bracket should be stable to avoid vibration effects.

5/ Range blind zone: There is a minimum measurement distance (blind zone) below the sensor, and sufficient space should be reserved when selecting. MIC Metering can customize the blind zone to meet some applications.
