Company Profile

Since over twenty years Sommer Messtechnik is well known for it's innovative and high-quality products in the manufacturing and development of measuring instruments and equipment. Today, Sommer GmbH is a specialist in sensor technology for meteorological and hydrological applications of environmental engineering operating on a world-wide scale.

We have built up an extensive body of knowledge through our work in the construction and technical support of measuring systems for avalanche alert and hydrographic services in Austria, above all in the alpine region – frequently in places remote from any infrastructure.

We are specialists for snow and water sensors and measurement systems, like for example ultrasonic snow depth sensors, equipement to measure the ice and liquid water content of snow, snow density, snow water equivalent or the run off in snow layers; furthermore radars for contact-free discharge measurement, flow velocity of water or tracer-systems.

Our vision defines a clear goal: to provide our vast experience and practical knowledge to our customers by supplying a diverse portfolio of products and services.  We endeavour to deliver sophisticated solutions to tasks of metrological and hydrological measuring. Our developers are constantly refining and perfecting our special sensory technology and equipment in the field of environemtal measurement engineering. Our world wide service and partner network ensures to service our customers' needs around the globe.

RQ-30

The RQ-30 is Sommer's solution for contact-free determination of discharges in rivers and open channels. With its combination of a velocity and level radar together with Sommer's modeling software RQ-Commander measuring and monitoring discharge is as comfortable and easy as it gets. Due to the contact-free design the RQ-30 is not endangered by flotsam during flood events.

TQ Tracer Systems

The discharge measurement is performed by using the well-established tracer-dilution method. The system can be deployed in turbulent rivers, creeks or waters for which data regarding the cross-section profile are not available or unknown. It is used salt (NaCl) as tracer material. After insertion of a known amount of tracer material two conductivity probes automatically determine the discharge. This way high plausibility and accurate results can be guaranteed.
Features and advantages

Simple, mobile discharge measurement
Reliable results even without knowledge and independent of the cross-section profile
Suitable for fast-flowing, turbulent waters or where access is limited
Environmentally friendly, harmless for water
Discharge values immediately available
Easy transmission of measurement data from the sensor to receiving device via Bluetooth
Convenient receiving of data on laptop
Real-time visualisation of measurement data
User-friendly guidance through the measurement by the included software TQ-Commander
Simultaneous measurement with up to four probes
Tracer material: salt (NaCl)
Probe type: conductivity probe
Compact and convenient: complete equipment securely packed in two cases
