Real-time Water Flow and Quality Monitoring Device

This technology is a hydrologic flow measurement device that can be deployed in confined spaces such as the roadside catch basins or outfalls from rooftops. Equipped with integrated sensors, this device can provide real-time data on flow conditions, sediment trapping, temperature, and water quality. The device can be applied to stormwater or meltwater monitoring in roadside catch basins (i.e., at the drain inlet) to be used for adaptive management of flood hazards, excessive chemical pollutants, sediment trapping, etc. Deployed at several locations and incorporated into an Internet of Things (IoT) network, real-time data acquired from these devices can be used to monitor and plan city-wide water management systems more efficiently.

Confined Space Reservoir Orifice Flow Meter

Stormwater/meltwater flow and quality measurement in confined spaces is hard to achieve as sediments and debris can cause damage to the sensors, increasing its cost of maintenance and outages. This new device is designed to handle the high amount of sediments and debris in roadside catch basins. The design of the water outlet provides differential flow rate, making the device suitable for different water flow conditions. The modular design of the device facilitates easy maintenance and addition of new sensing components. Data collected by the device can either be stored on-site or transmitted to remote locations where the data can be monitored and analyzed in real-time.
