When the city of Miami Florida opened a ¾ mile tunnel roadway 127 ft. under the bay they knew they would need to have a plan in place to prevent flooding in case of a storm or hurricane. The tunnel is four lanes wide and extends from the mainland to the cruise line ports.
APG's PT-500 Submersible Pressure Sensors were installed in pump rooms located under the tunnel roadway. The sensors serve as part of a redundant water level monitoring system. The sensors are connected by Programmable Logic Controllers (PLC) to the tunnel SCADA system.
If the water level climbs too high, such as during a severe storm or Hurricane, the water level detection capability of the PT-500 assist in activating pumps that remove the rising water so the tunnel will not be flooded.
