Hydrostatic liquid level measurement in water and wastewater management

Hydrostatic liquid level measurement is extremely important in the context of water and wastewater management. This type of measurement uses the hydrostatic pressure of a liquid to determine its level. This pressure increases in proportion to the depth of immersion of the probe, which enables accurate and reliable measurements. Hydrostatic probes are crucial in monitoring levels in retention basins, settling tanks or sewers, enabling effective control of wastewater treatment processes
wastewater.

It is important that the probes are resistant to corrosion and aggressive chemicals, which is typical in wastewater environments. In addition, it is important that the probes are designed to ensure the stability of measurements under varying environmental conditions, such as fluctuations in the chemical composition of wastewater and temperature fluctuations. Modern technologies used in hydrostatic probes, such as piezoresistive sensors, contribute to the accuracy, reliability and durability of these devices, which is key to ensuring the continuity and efficiency of processes in water and wastewater management.

Selecting a hydrostatic level probe for wastewater

When choosing a hydrostatic level probe for wastewater, several key aspects should be considered. Firstly, the probe's measurement range must be matched to the depth of the wastewater tank. Models like the MAERA F27, specifically designed for operation in a wastewater environment, offer a wide measurement range from 50 mbar to 1.6 bar, which is ideal for various applications in this industry.

Resistance to corrosion and aggressive chemical substances is another important factor. Our probes, such as the MAERA S26 and MAERA S28, are made from stainless steel, which copes excellently with the harsh conditions found in wastewater.

Measurement accuracy is crucial for ensuring effective monitoring and management of the wastewater system. Additionally, specific environmental conditions in which the probe will operate should be considered. For example, for wastewater with high temperatures or extreme contamination, a probe with appropriate features should be chosen, such as the MAERA F27, which is adapted to work even in extreme conditions, e.g., temperatures from -20 to +60°C.

Installation and maintenance of hydrostatic level probes

The installation of a hydrostatic probe in sewage systems requires precise placement of the device in a location where it can accurately measure the liquid level, yet is not susceptible to mechanical damage. It is important that the probe is submerged vertically and has the freedom to move in case of an increase in the sewage level. Maintenance
of the probe should include regular cleaning, especially in areas where contaminants can accumulate. This process should be repeated preferably every 3-6 months, depending on the degree of environmental contamination. Another important aspect is the inspection of the cable's integrity and the casing once a year. Calibration of the probe once a year is equally important to ensure the continuous accuracy of the measurements.

Hydrostatic level probes for water and wastewater – summary

In summary, hydrostatic probes play a crucial role in wastewater treatment plants and pumping stations. Utilizing the principle of hydrostatic pressure, they enable precise measurement of wastewater levels in tanks, which is essential for the effective monitoring and management of wastewater systems. The selection of a suitable hydrostatic probe should consider the measurement range, resistance to corrosion and aggressive substances, measurement accuracy, and the specific environmental conditions present in the wastewater system. Models such as the MAERA F27 offer a wide measurement range and are adapted for operation in extreme conditions. We also have other high-quality hydrostatic probes in our range, like the MAERA S26 and MAERA S28, which ensure reliability under tough conditions. Regarding installation and maintenance, it is important that the probe is properly positioned and submerged vertically. Regular cleaning every 3-6 months, annual inspections of the cable and housing integrity, and yearly calibration are key to maintaining the accuracy and longevity of the probe.
