Measuring water levels accurately

Today, it has become important to work out ways in which water and wastewater levels can be measured more accurately, reliably and cost-efficiently. The article highlights the usage of the wireless radar level sensor from Senz2 that is integrated into a powerful stand-alone solution. A read on…

Expanding the measurement network and gaining new insights with reliable water level data has never been easier. As such, having a solution that lets you measure the water and wastewater levels is essential. 

The Challenge

According to the International Resource Panel of the United Nations Environment Program (UNEP):

“An estimated US$41 trillion is required to refurbish the old, and build new urban infrastructures, over the period 2005–2030: $22.6 trillion for water systems, $9 trillion for energy, $7.8 trillion for road and rail infrastructure, and $1.6 trillion for air- and sea-ports. These investments will ensure the welfare of urban populations and build the foundation for the next generation of great cities.” (source: “City-Level Decoupling” report)

This means that the required investments in Water System infrastructure (US$22.6 trillion) are larger than required investments in Energy, Mobility and Main Port infrastructures added together globally (US$18.4 trillion) until 2030.

To plan these enormous investments responsibly, insight into the current performance of water system infrastructures is needed. Indeed, modelling alone is not enough. Instead, we need accurate and reliable measurement data to feed and calibrate our models

How To Address The Problem?

It is given the fact that measuring water levels of groundwater, surface water, and wastewater is time-consuming and costly. In most cases, measurement data are unreliable. This is because of the use of inaccurate sensors that demand periodic maintenance and re-calibration.

Also, within a large share of the existing level measurement networks, human intervention in data reading and validation is still indispensable. In addition to the costs of human intervention, human actions are unfortunately a source of errors.

In light of this, one must gather all the data regarding the current performance of the water system infrastructures to provide actionable insights to the water authorities and infrastructure managers. So, it is necessary to develop sensors and measurement networks that:

  • can work autonomously, without human intervention;
  • are robust and maintenance free;
  • don’t need any additional power-or data infrastructure;
  • provide a stable and reliable measurement method in all (weather) conditions;
  • and are cost efficient, calculated as total cost of ownership (TCO)


The Solution

As a result, the industry standard for high quality and reliable (non-contact) level measurements transforms with space radar level transmitters. Radar technology, in general, is known for its reliability and stable performance in all conditions. In fact, it is by far the best distance measurement technology in aviation, marine and automotive applications.

However, radar is a complex measuring method, which requires expensive hardware and peripherals, highly-skilled operators and serious installation costs.

Based on brand new single-chip radar technology, the company delivers a breakthrough in remote monitoring of water levels. So, it allows every water authority and water management organization to use the best level measurement technology (radar).

Therefore, there is no need for any additional infrastructure or skilled operators. This means it allows high-quality measurements and validated data in real-time with a minimum of installation and maintenance costs: “Radar made simple!”

The Benefits

This wireless sensor’s long battery life, global connectivity and easy installation and setup make it ideal for use in mobile and remote measurement applications.

In fact, this solution fits perfectly with initiatives for expanding existing measurement networks. As a result, one can gain more insights into current water system infrastructures.

The MakeSenZ2 Portal supports the sensor. It has integrated data management functionalities and SenZ2 API. This allows for further data integration in third-party information systems and platforms.

The main benefits for the water sector are as follows:

  • reliable and accurate fill-level measurement data;
  • securely stored and available 24/7;
  • exact measuring results independent of the product;
  • process and ambient or weather conditions;
  • easy to use wireless operations
  • no infrastructure needed, works out of the box;
  • 5-year battery-life and maintenance-free operations;
  • direct insights into sensor data, sensor status, and sensor settings through the online platform;
  • remote, over the air, configurations, and updates


The wireless radar level sensor from Senz2, therefore, meets the demands for more accurate management of water levels. As a way ahead, this seems to be a real game-changer in water system infrastructure!
