Non-contact and Reliable Open Channel Flow Monitoring with New Radar Sensor


SOMMER Messtechnik is expanding its radar sensor equipment to the water and wastewater market. The new SOMMER SQ Flow Meter Series measures reliably and without direct contact to the (waste) water both, the water level and the flow velocity. With the cross section profile given and based on an advanced, self-adapting hydraulic model, the smart sensor conveniently outputs your actual and exact discharge rates at all times. With the different sensor types SQ- 3, SQ-6 and SQ-8R according to the maximum water level to be measured, the SQ Series is most suitable for installations in wastewater, sewer systems and for open channel flow measurement.


More than three decades of experience in hydrology and environmental monitoring build the ground for SOMMER’s newest innovations. The SQ is suggested for all kinds of open technical channels as well as semi-filled pipes and ducts, where submerged type sensors frequently fail due to soiling and deposits on the equipment. Incorporating the latest radar and ultrasonic technology the SQ Flow Meter however ensures reliable measurements avoiding direct contact with the water. Consequently expenses for maintenance and service are reduced to a minimum. The sensor can be installed very easily from above the water body (e.g. on a cross-beam) where it is to be reached much easier too.


Various interface connections like SDI-12, RS 485, Modbus, Profibus, analogue or pulse signal guarantee a trouble- free implementation into new or also existing systems. The SQ Flow Meter certainly is a must-have flow monitoring equipment to all responsible in water management, sewage systems and wastewater treatment plants.

Sensors from leading meteorological specialists, Biral (UK), are currently being used as part of a research mission in Antarctica, headed by a French research group.


The APRES3 campaign is a long term project with the aim of measuring precipitation in Antarctica, as well as monitoring climate change to understand the effect this has on the ice sheets. Biral’s VPF-730 Visibility and Present Weather Sensors form a part of an extensive range of equipment being used by the group, to help draw conclusions on the rate at which snow falls on the surface of Antarctica.

Sensors from leading meteorological specialists, Biral, are currently being used as part of a research mission in Antarctica, headed by a French research group.


The group recognised the difficulty of measuring solid precipitation, given the extreme conditions and locations of the research, and therefore has deployed instruments, including Biral’s VPF-730, to receive the measurements at the French Antarctic Stations. They then use the measurements to calibrate and validate snow fall estimates by satellite and improve the building of climate models. It is these models that allow the group to generate better predictions over a century time scale and estimate the impact of climate on the sea-level.


The experiment takes place at the French station, Dumont d’Urville and is supported by the French Polar Institute (IPEV), French National Science Foundation (ANR), and French Space Agency (CNES).


Christophe Genthon, Research Scientist at the Laboratory of Glaciology and Environmental Geophysics commented, “The project uses Biral’s VPF-730 to measure in situ snow fall and blowing snow, and help us to differentiate the two. We hope that this will improve our knowledge and understanding of precipitation and blowing snow in Antarctica, which is the only continent where precipitation is still largely unknown because it is so difficult to measure. We found Biral’s design to be particularly rugged which is ideal for this project due to the extreme conditions.”


Biral’s VPF-730 Visibility and Present Weather Sensors are designed to deliver high levels of accuracy, reliability and durability for a range of meteorological applications. The sensors come in a compact, robust package that is highly corrosion resistant with a hard coat anodised finish, making it particularly suitable for applications, like the Antarctic or offshore platforms, which see challenging weather conditions.


The sensors are designed with an open sensor head to allow the free passage of air to improve the accuracy of measurements, with the ability to receive measurements within a 10m to 75km range. The sensors also use a backscatter receiver to help distinguish frozen from liquid precipitation.
