Non-contact discharge measurement by means of radar technology for open rivers. The RQ-30 is a sensor for continuous discharge measurement of rivers, open channels and canals with known cross-section profile. The sensor uses innovative radar technology to measure velocity, water level and discharge. It enables reliable, non-contact measurement without the need for structural work in the water.

Mobile measuring system for non-contact discharge measurement. With the mobile measuring device RP-30 (Radar Profiler) a surface velocity profile from rivers and channels is created and together with the data of the river cross-section and water level the discharge is determined. - A very helpful measuring device especially for the use in flood conditions.

Mobile discharge measurement system for turbulent rivers with unknown cross-section profile - Salt Tracer. 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.

WELL PROVEN RQ-30 DISCHARGE MEASUREMENT WITH DATA LOGGER AND DATA TRANSMISSION IN COMPACT Housing. The RQ-30 ADMS is an all-in-one discharge measurement System. It contains the non-contact flow velocity and water level sensors of the RQ- 30 and applies the same algorithms and model to calculate the discharge in the RQ-30 sensor.

Discharge measurement for wide rivers with inhomogeneous distribution of flow velocity. With the system of one master-radar sensor and several slave-radar sensors the velocity is measured at several spots throughout the whole water cross-section. Therefore a very high accuracy of the discharge measurement is guaranteed also for very wide water bodies.

Discharge measurement for open rivers with external water level data. Innovative radar sensor for non-contact discharge measurement of rivers, open channels and canals with the possibility to use and integrate external water level data.

Radar sensor for contact-free velocity measurement. The flow velocity sensor RG-30 has been designed for contact-free measurements of the surface flow velocity of rivers and channels by means of radar technology.

Contact-free water level measurement. The RL-15 / RL-35 is a highly accurate measuring device to measure the surface water level without direct contact to the medium.

The PTM– Pressure probe, measures water level and temperature. It offers long-term measurement stability with an extremely high accuracy of 0.05%. Using an SDI-12 interface (analog 4-20mA is optional) makes the integration simple and easy. With a robust stainless steel housing (titanium is optional) and a rugged cable, this sensor is ideal for monitoring water levels in a variety of applications.

The measurement principle of the SOMQUALITY-NTU turbidity sensor is based on infrared light scatter at an angle of 90°. Thanks to the measurementat a wavelength of 880 nm and the wide detection range of 0 to 4`000 NTU, the sensor can be used in varous water and wastewater treatment applications. Apart from turbidity, the SOMQUALITY-NTU also measures the medium temperature and the suspended solids content.
