The new DR7100 with its more advanced design solutions has higher signal dynamics. Sharper Pulses measure thinner interfaces. The superior Time Base Stability allows better reproductibility, which translates to better reliability.

Probe Types and Materials for all Applications
Most Stable Measurement
Despite disturbances such as strongly agitated surfaces, foam and coating of the probe or fine dust in the tank, DR7100 will continue to measure where competitors’ devices fail.
Measures any Product ...
Most 2-wire TDR devices measure down to a dielectric of 1.5. As a result, many organic compounds are not measured properly. DR7100 measures down to 1.4 (and even 1.1 using superior tank-bottom following mode).
... in any Application
5 different probes means there’s not an application that we can’t handle.
Makes Level Gauging Easier than Ever
Wizard Works Wonders
Setting up a 2-wire level gauge couldn’t be easier:
Simply fit the gauge to the tank, wire it up and switch it on:
-
Step 1 – The DR7100 tests itself to make sure its electronics are working perfectly.
-
Step 2 – The DR7100s Wizard walks you through a simple series of questions to define your tank and the product you want to measure.
-
Step 3 – That’s all you need. Your DR7100 is already measuring.
