RQ-30ADMS

Product catalog summary

Overview
The RQ-30 ADMS is a comprehensive discharge measurement system designed for spot measurements, temporary applications, or long-term installations. It features contact-free flow velocity and water level sensors, utilizing algorithms to compute water discharge. The system supports autonomous operation for several weeks with rechargeable batteries and can connect to a solar panel via an integrated charge controller. Data transmission is facilitated through wireless connections to FTP and HTTP servers, with notifications available via email and SMS.

Versions
Two versions are available: the 15m and 35m automatic discharge measurement systems.

Scope of Delivery
The package includes the RQ-30 ADMS in the selected version, an MRL-7 data logger with a 3G modem and planar antenna, a manual, and Commander Software on a USB stick. An optional mobile charger is also available.

Accessories
Available accessories include a lead-acid battery (12 VDC/12 Ah) and a 50W solar panel with a 60-mm tube mount and 5-m cable.
