Complete kits for flood monitoring and alerts systems

Being prepared for requires mea- surement and notifi- cation of water level, 1 velocity, and precipita- tion. This guide will help you choose the right equipment and install a flood alert system that can help you coordinate emer- gency response and activate alarms for the public.

4 Data Transmission

Transmitting and alarming are two important compo- nents of a 4 2 system. These three precon- figured options transmit data quickly to the people who need to act on it. Data to Web: Transmitting water level, precipitation, and velocity data to a public web site is simple with the EcoNet data logger. The data are sent directly from the field to a web server where information can be shared with the public and email alerts sent to specific individuals. The data logger uses the cellular network and is autonomous of local com- puters and software.

1 3 ALERT Network: If a dedi- cated local ALERT network is available, consider using a transmitter that supports stan- dard ALERT protocols. The network operates through a series of repeater stations and transmits messages over RF in conjunction with the 2 Precipitation 3 Discharge local radio authority. The data are relayed to a local In most flood alert systems, A side-looking or up-looking control center, which runs precipitation is an early current meter may be required software to manage data warning of floods.
