Why is it important to measure water flow?
Measuring water flow is essential to ensure efficient management of water resources, optimize the use of infrastructures, prevent flooding, supply drinking water and assess environmental impact.
How do I measure flow using a water level measurement?
Measuring flow from the water level involves using instruments such as pressure or ultrasound sensors. The flowrate of a stream can be estimated by combining these data with hydraulic models (height/flow curves).
How do you measure the water level of groundwater?
The water level of groundwater is measured via piezometers, tubes fitted with sensors. The data obtained is used to help in the sustainable management of water resources, preventing overuse, ensuring the safety of drinking water supplies and protecting the environment.

FAQ on flow measurement
How does an ultrasonic flowmeter work? What advantages are there in relation to other flowmeters?
The ultrasonic flowmeter uses sound waves to measure the flow rate of a fluid. Sensors emit ultrasound through the fluid, measuring the transit time to calculate the velocity of the fluid, and then determine the flow rate according to the cross-section of the channel. Ultrasonic flowmeters do not require direct contact with the fluid, thus avoiding wear and tear on the sensor.
Where should I install my ultrasonic flowmeter?
For the best results, place the ultrasonic flowmeter upstream of the venturi channel, threshold or overflow gauge, where the flow rate is most stable. Avoid turbulent areas and ensure a sufficiently long straight section upstream and downstream. Mount the flowmeter at a distance and exact angle, according to our recommendations. Accurate calibration is also required for reliable measurements.
How to choose the right venturi channel model from the AQUALABO range
The choice of venturi channel or metering model will depend on several factors: the maximum expected flow rate in m3/h or L/s, type of fluid passing through the channel (clear or loaded), and installation conditions (U-shaped pipe, limited space, ability to carry out civil engineering or not, etc.)
How to accurately perform a manual piezometric level measurement?
To measure accurately, lower the tape or probe slowly until it reaches the surface of the water, avoiding sudden movements. Then read the depth on the tape measure as the probe emits a light and/or sound signal.
