Level SOMLEVEL-30. The SOMLEVEL instruments are contact-free level sensors typically applied in hydrology and waste water treatment to determine water levels of rivers, channels, tanks and basins. Other areas of application include the filling level of bulk solids in silos and bunkers.
Nov 25, 2020 · The WHO Guidelines on physical activity and sedentary behaviour provide evidence-based public health recommendations for children, adolescents, adults and older adults on the amount of physical activity (frequency, intensity and duration) required to offer significant health benefits and mitigate health risks. For the first time ...

Non-contact measurement, maintenance-free systemCalculation of discharge by continuous measurement of flow velocity and water levelNo construction measures necessary in the sewerWaterproof and resistant housing also for use in aggressive environmentsThe SQ-R is specially designed for municipal and industrial applications in wastewater treatment plants, sewers and process water circuits. For example, the amount of wastewater entering a treatment plant can be monitored to control the facility and allocate wastewater costs. Furthermore, the duration and frequency of rain and flood events can be r...
Due to its compact design and flexible mounting device, the sensor is very easy to install, for example under bridges or extensions, on ceilings of sewers or in manholes. The non-contact measuring technology has the decisive advantage that the sensor can be mounted above the water level. Thus, the SQ-R can be easily installed, is readily accessible...
For remote monitoring sites without grid connection, the SQ-R can also be operated autonomously: In combination with a data logger, a data transmission modem, a powerful battery and an adequate solar module, the SQ-R can be upgraded to an independent system. Optionally, it can also be equipped with a camera to visualize the conditions on site.

Dec 4, 2020 · That’s mean energy level separation increases with n. Fermi Energy. At T=0K, there will be no thermal excitation i.e., all the electrons remain at ground level. For a large value of n, there will be the uppermost filled level at T=0K called the Fermi level. This is the last filled level. The energy of the Fermi level is called Fermi Energy.
The summer solstice is the day with the longest period of daylight and shortest night of the year in that hemisphere, when the sun is at its highest position in the sky. At either pole there is continuous daylight at the time of its summer solstice. The opposite event is the winter solstice. The summer solstice occurs during the hemisphere's ...
