Designed to identify flood conditions and wirelessly share status with adjacent traffic control devices. Operates autonomously with its own sensing, averaging, memory, and output control capabilities.
Request informationThe Integrated Flood Detection System (IFDS) comprises multiple nodes and areas, functions autonomously, and provides information and control commands to the traffic signal system. This website summarizes the hardware and software behavior exactly as documented in the operation manual.
Sense nodes poll ultrasonic and level sensors at 1‑second intervals and broadcast on 915 MHz.
Receive nodes compare readings against stored warning and activation levels and drive outputs.
Compute unit runs IFMS for status, logging, configuration, and visualization. System can operate without compute unit.
915 MHz radio • Moving average (100) • Override modes
Collects ultrasonic and level sensor data at 1 s intervals; performs edge calculations; broadcasts to receive nodes on 915 MHz.
Stores thresholds; compares readings; actuates outputs and provides system status to the compute unit.
Relays signals from the receive node to external systems such as LED warning signs or controller logic inputs.
Aggregates data for logging/verification and enables configuration via the IFMS application. IFDS can operate without it.
Directly connected to the compute unit. Reports 1‑minute, 1‑hour, 24‑hour, and total rainfall (mm). Piezoelectric; mount with no obstruction above.
Measures distance to water surface for real‑time levels and a 100‑point moving average. Data is sent to receive node and logged.
Two sensors used to assess warning/actuation. Software supports 1‑of‑2 or 2‑of‑2 polling. Mount heights adjustable and calibrated at install.
Actions rely on 100 recent readings. Power cycling a node resets its rolling sample; the other node may retain its last 100 if still powered.
Default mode uses the receive node calculator; sensor node calculations require manual setting and calibration.
Receive node can follow the sensor node’s recommended state (override indicated as Yellow). Transmission Packet Number aids traceability.
Visual overview of phases with colors (Red/Yellow/Green) and pedestrian indications (Walk/Clear/Don’t Walk). Preemption may override signal control; LED warning signs remain active.
Compatible with NEMA and ATC controllers up to 16 phases. Shows phase calls, pedestrian calls, detector calls, overlaps, and omit requests which are logged with flood events.
Logs precipitation on value change and presents 1‑minute, 1‑hour, 24‑hour, and total rainfall measurements in millimeters.
Displays current and 100‑point moving average values from both sensor and receive nodes to illustrate stabilization and validation timing.

Use with accompanying electrical drawings for installation. Configure NTCIP port and ultrasound thresholds per site. Maintain sensor casings (keep water ingress holes clear).
