We use these instruments in our research facilities as well as in field studies in rivers, coastal areas and estuaries. Because of this, we know that our instruments are robust, accurate and easy to use. Our instruments are always calibrated before use.
We also advise on setting up measurement campaigns. This includes advice on which instruments are needed for a specific measurement but also whether it is possible to adapt the instruments to the situation. Due to our own work in the field and research facilities, we now have a lot of experience with this.
An example is the meters adapted for the Delta flume, which are equipped with measuring electrodes (wires) made of a titanium alloy with optimal electrical and mechanical properties. This gives minimal disturbance to the water, they give robust signals without outliers and provide excellent accuracy and linearity over a water level range of eight meters.
