The Street Dynamics Flood Sensor
When It Rains, It Pours…
Many communities have a few roads, hiking trails, or other areas that are prone to flooding, but constantly monitoring these areas can be time-consuming and resource-intense. In the United States, an average of 2 out of every 3 flood-related deaths occur in vehicles, making this a serious safety issue.
The Street Dynamics Flood Sensor pairs with a Street Dynamics PMG message sign to automatically notify residents about flood conditions, triggering the sign to display messages such as “FLOOD ZONE,” “HIGH WATER,” or “ROAD CLOSED” depending on the circumstances.
You can connect up to three flood sensors to one PMG, allowing you to display different warnings on your sign as water levels rise and recede.
About The PMG Flood Sensor
The Flood Sensor consists of a tamper-proof metal enclosure which houses the fluid sensor. It is designed to be able to be completely submerged in water with no damage.
Connect 3 Devices to One PMG
Up to three sensors can be attached to a single PMG utilizing the 3-Port Expander, allowing for progressive levels of alert escalation and de-escalation based on the current water level.
Each unit has its own cable and can be located up to 1,025’ (312 m) away from the PMG.
Real Time Updates
Combining multiple sensors allow you to deliver the correct warning based on actual water levels.
As each Flood Sensor is triggered, it causes a different message to appear on the PMG. When the flooding is over, your PMG will resume showing its normally scheduled display sequences.
The Street Dynamics PMG
Pole Mounted Graphic Display
Our most versatile sign, the PMG is most frequently used as a pole-mounted sign. However, it can be used as a radar speed sign, a traffic data collector, and a variable messaging sign to display virtually any message, graphic, or animation you desire. It can be mounted it to a pole or vehicle, or, using the optional handle and feet, can stand on its own anywhere you’d like.
The Street Dynamics Web Portal allows you to access any connected PMGs remotely. Update displayed messages, schedule message sequences months or even years in advance, and create reports with your collected traffic data. You can also connect to your PMG directly using a PC or via the “Speed Sign” app (available for iOS and Android).
Add an MUTCD-compliant “YOUR SPEED” frame to instantly transform your sign into a traffic calming device perfect for school zones, HOAs, and busy streets in your community.
The PMG can also be paired with our Flood Sensors or other NTCIP and external trigger devices to automatically send alerts about road closures or other hazardous driving conditions ahead.
How the Flood Sensor Works
Setting up your Flood Sensors is easy.
First, evaluate the road where you are experiencing flooding. Depending on how many Flood Sensors you have purchased, select between 1-3 locations to place your Flood Sensor units. Remember, your PMG must be within 1,025 feet (312 meters) of your farthest Flood Sensor.
You can mount your Flood Sensors beside the road, alongside your water source, or anywhere in between. Remember, to trigger your Flood Sensor, water must reach the center of the unit (indicated by the QR code sticker on the side of the sensor case).
Flood Sensors can be attached to a variety of surfaces using the included bolts or your own fasteners.
Once you have mounted your Flood Sensors, simply use the included cable to attach each unit to your PMG sign (or use your own cable using one of our handy connector kits). A single Flood Sensor can be connected directly to your PMG, while multiple unit setups will utilize a 3-port I/O expander unit.
You can then program your PMG to display a unique message when each Flood Sensor is triggered, such as “ROAD CLOSED,” “FLOOD AREA,” or “SLOW DOWN.” When the water levels receive and the PMG is not being triggered by a Flood Sensor, it will revert back to its regular settings automatically.
If your PMG features solar power, you have now created a virtually “set-it-and-forget-it” flood safety system that will work hard to warn residents and keep your streets safer during emergency conditions.
Who is the Flood Sensor For?
The Flood Sensor is not just for city streets! Many hiking trails and parks are located by lakes, rivers, streams, and in other flood-prone areas. Colleges and universities may also have areas on their campuses that become unsafe during inclement weather. Airports, military bases, HOAs, beaches, marinas, and more may also find that they have places where high water levels can create dangerous conditions.
Colleges & Universities
Homeowner Associations (HOAs)
Beaches, Parks, & Marinas
Having strategically placed Flood Sensors can free up emergency-response teams during bad weather conditions since you will no longer have to send out personnel to monitor flood-prone areas. They can also save lives, especially when flooding occurs around bends or areas on the road where drivers could encounter flooded streets unexpectedly.
