How Do I Ship A Meter Back?

It’s easy.  Just choose RETURN EQUIPMENT from the menu and fill out the ticket.  This will help us keep track of your equipment through each phase of the service we provide.  Otherwise, email or call us and we will set you right up!


Why Can't I Calibrate My Own Equipment?

Accurate calibration of flow instrumentation requires a special facility.  Terralogger uses state of the art equipment along with a massive sensor towing basin.  We have several recirculating flow loops as well.


Can you calibrate my instruments at my location?

We can perform in-situ calibrations, which is flow profiling and “tuning” your instrument to its monitoring location.


What kind of equipment do you have available for rent?

Terralogger carries has one of the largest fleets of flow meters and rain gauges available for rent.  We carry the Marsh-McBirney/Hach Flo-Tote 3, the Savannah Environmental, Inc. Rainger Rain gauge, and the Flo-Mate handheld velocity meter.


What if you can't repair a unit?

In the rare case we cannot repair an instrument, we will notify you and ship it back.  The only fees incurred would be shipping .
