Full Description of Rain Gauges
and Lake Elevation Sensors

The ActiveÔ Series Hydrological Monitoring Stations are located on the shores of select waterbodies to monitor rainfall and water elevation, using a tipping bucket rain gauge and a submersible pressure transducer (PT), respectively. The data is transmitted from each hydrological monitoring station to a receiver at the City’s Stormwater - Lake Enhancement Building via an RF transmitter. The data is automatically uploaded to the PraxSoft website in real time. Information is sent and recorded for each tip of the rain bucket and/or change in lake elevation.

There are two types of hardware used in the ActiveÔ Series Hydrological Monitoring System: the rain gauge / standpipe sites, which house the rain gauge and water elevation sensors, and the lake level sites, which only measure water elevation. Each of these systems has the ability to accommodate multiple sensors and to communicate the data measured from the sensors back to a central server and database. The rain gauge / standpipe sites use the Model 2400 Tipping Bucket Rain Gauge Top Section designed and manufactured by High Sierra Electronics. The lake level sites are designed and manufactured by PraxSoft. Both manufacturers have proprietary rights to their equipment, software, and system functionality. The PraxSoft ActiveÔ Series system architecture provides a means to transmit remote hydrological data and gives the customer the ability to use the system as a backbone for various sensors, asset management, and monitoring applications.

The electronic equipment within the hydrological monitoring stations is powered by a 12V battery that receives charge from a 1 - 5 watt solar panel. All electronics are housed in either the 10 foot standpipe (painted brown or white) or in a NEMA 4X waterproof enclosure, similar to an electrical breaker box, on a 6 foot galvanized metal pole. On both the standpipe and the NEMA configuration, three cables run into the unit: a cable from the PT, a cable from the antenna / lightning suppressor, and a cable from the solar panel. The standpipe has an additional cable for the rain gauge sensor.

A PVC conduit, which houses the PT, runs from the NEMA enclosure and/or standpipe into the lake or waterbody and is anchored to the floor. The conduit allows the PT to be inserted into the water while protecting the cable and providing serviceability. The PT cable length is dependent on the appropriate operating depth of that waterbody.

City of Orlando Stormwater Section can supply specific storm related data such as storm duration or per minute intensities. If this type of data is needed please contact Christy Wood, Environmental specialist at 407.246.2051 or email.
