7. Measurements with TQ-Commander
7.1. Introduction
The measurement procedure
contains the following steps:
1. Switch on the TQ-Amps
2. Establish the Bluetooth-
connection
3. Input information about the
measuring site or station
4. Perform a calibration for the
compensation of the local water
characteristics (temperature
and chemical composition)
5. Perform the measurement of
the conductivity (Fluorescein /
Rhodamine WT) while the
tracer passes the sensors and
the discharge is automatically
calculated
The software TQ-Commander guides the user through all necessary steps of a complete measurement
after clicking on Measurement (F9) in the menu:
o Connecting the TQ-Amp ( 7.2) and if necessary performing the first-time sensor setup ( Fehler!
Verweisquelle konnte nicht gefunden werden.)
o Placing the probes in the water body to be measured to get them to the same temperature.
o Input of information for the report ( Fehler! Verweisquelle konnte nicht gefunden werden.)
o Calibrating the sensors ( Fehler! Verweisquelle konnte nicht gefunden werden.)
o Estimation of the tracer amount needed and injection of the tracer solution into the river.
It is important that the complete tracer amount is injected. In most cases the tracer
solution is prepared in a bucket for an easy and complete injection.
o Placing the sensors in the water body ( 5.3)
