Discharge Radar RQ-30 ADMS

WELL PROVEN RQ-30 DISCHARGE MEASUREMENT WITH DATA LOGGER AND DATA TRANSMISSION IN COMPACT HOUSING

The RQ-30 ADMS is an all-in-one discharge measurement System. It contains the non-contact flow velocity and water level sensors of the RQ- 30 and applies the same algorithms and model to calculate the discharge in the RQ-30 sensor.

The rechargeable batteries allow autonomous operation for several month and the integrated charge controller provides for an easy connection of a solar panel.  The integrated data logger of the RQ-30 ADMS offers wireless 2-way data communication. The 2-way communication makes it possible to remotely access the sensor and data logger anytime from anywhere.

Notifications by E-mail and SMS are a standard feature of the RQ-30 ADMS. Optionally, the RQ-30 ADMS can be equipped with a SOMMER Time laps camera for visual surveillance of the monitoring site.
