  • Water Level Measurements-Part 1

    Confused about which instrumentation to use in your water level monitoring system? In-Situ offers two categories of pressure sensors for water level measurements: absolute or non-vented sensors, and gauged or vented sensors. They look the same and both measure pressure and water level, but they have drastically different applications, outputs and accuracy. The absolute (or non-vented) water level ...

  • Open Channel Flow - The use of Level sensors for open channel flow measurement

    Open Channel Flow - The use of Level sensors for open channel flow measurement Level sensors from SolidAT are implemented in Open Channel Flow applications. In these types of applications, the level sensor is installed above a special water flow structure and accurately measures level of flowing water or wastewater. The sensor then calculates flow through the structure ...

  • Estimation of combined sewer overflow discharge: a software sensor approach based on local water level measurements

    Combined sewer overflow (CSO) structures are constructed to effectively discharge excess water during heavy rainfall, to protect the urban drainage system from hydraulic overload. Consequently, most CSO structures are not constructed according to basic hydraulic principles for ideal measurement weirs. It can, therefore, be a challenge to quantify the discharges from CSOs. Quantification of CSO ...

  • Determination of diurnal water level fluctuations in headwaters

    The aim of this paper is to study diurnal fluctuations of the water level in streams draining headwaters and to identify the controlling factors. The fieldwork was carried out in the Gryżynka River catchment, western Poland. The water levels of three streams draining into the headwaters via a group of springs were monitored in the years 2011–2014. Changes in the water pressure and water ...
