Sommer TQ-S Saltsporer

Sommer TQ-S saltsporsystem er en mobil enhet for å måle strømning i turbulente elver med ukjent tverrsnittprofil. Den bruker salt som et sporstoffmateriale for å måle ledningsevnen til det rennende vatnet, og fra dette beregne vannføring.

  • Enkel overføring av data fra sensor til PC via Bluetooth-kommunikasjon
  • Vannføringsverdier umiddelbart tilgjengelig gjennom medfølgende TQ-Commander programvare
  • Leveres komplett med alt nødvendig utstyr pakket i 2 bærevesker


The Sommer TQ-S salt tracer system is a mobile discharge measurement system. The discharge measurement is performed by using the proven tracer-dilution method. It can be deployed in turbulent rivers, creeks or waters for which data regarding the cross-section profile are not available. Salt is used as a tracer material. After insertion of a known amount of tracer material, two conductivity probes are used to determine the discharge.

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
Fields of Application

The TQ-tracer system is especially suitable for fast-flowing, turbulent waters with complex cross sections, for example, mountain streams, small brooks, tributaries or even fish ladders. The measuring device is used particularly in hydrometry as well as by engineering offices, civil engineers or power plant operators, for instance for control measurements or for evaluating projects.


The tracer dilution method can be applied for discharge measurement in all waters in which a thorough mixing of the tracer ensues. High turbulences, alternating cross sections and stones promote the mixing process and therefore, have a positive effect on the measurement. For particularly turbulent waters and very high flow velocities there is a model available with robust reinforcement. The user-friendly software TQ-Commander leads comfortably through the measurement and provides a full measuring report.
