OTT RLS Radar Water Level Sensor

Overview
The OTT RLS is a non-contact radar level sensor with pulse radar technology that is ideal for monitoring in remote areas and applications where conventional measuring systems are unsuitable. The RLS accurately and efficiently measures surface water level with a non-contact distance range of up to 115 feet above the water. The sensor is IP67 waterproof and has extremely low power consumption, making it ideal for solar-charged monitoring systems.

Revolutionary
The radar level sensor uses a revolutionary level measurement technology, meeting the USGS accuracy requirement of +/-0.01 feet. Two antennas are enclosed in a compact housing and transmit pulses toward the water surface. The time delay from transmission to receipt is proportional to the distance between the sensor and the water surface. A sampling rate of 16 Hz (16 measurements/second) with 20-second averaging minimizes water surface conditions such as waves and turbulence. The RLS does not require calibration and is unaffected by air temperature, humidity, flood events, floating debris, or contaminated water.

Questions & Answers
Does the sensor have to be connected to a data logger?
Yes, the sensor does not have logging capabilities and needs to be integrated with a data logger. Sensor output options are SDI-12, SDI-12 via RS-485 and 4-20mA.
What is the difference between radar and ultrasonic sensing technologies?
While ultrasonic sensors emit high frequency (20 kHz to 200 kHz) acoustic waves, radar sensors use radio-frequency signals (1GHz to 60 GHz) and readings are generally less affected by pressure, temperature and moisture changes.
How is the level sensor installed?
The radar level sensor is mounted to a structure so that the radar beam is perpendicular to the surface of the water. A guide for installation and site selection can be found here: https://www.fondriest.com/pdf/ott_rls_install.pdf

Monitoring Hurricanes and Predicting Flooding in the Age of Climate Change

Still recovering from Hurricane Helene, which caused extreme precipitation, flooding, landslides, and other environmental disasters associated with severe weather, the southeastern part of the U.S. is predicted to be hit by another storm, Hurricane Milton. With Hurricane Helene having made landfall only a little over a week ago on September 27 th , many communities are still recovering.  ABC reports that over 230 people have been killed as a result of flooding and destruction caused by Helene, with many still missing. Residents in these heavily impacted states, such as Florida, Georgia, South Carolina, North Carolina, Virginia and Tennessee, are still searching through the rubble of homes, urban centers, and hospitals for loved ones and belongings.

Reintroducing Historically Native Fish in America’s Largest Wilderness

Among the dozens of publicly protected national parks, hundreds of wilderness areas, and thousands of state parks in the contiguous U.S., none are larger than the Adirondack Park, a 6 million-acre wilderness area that spreads across upstate New York.  With 3,000 lakes and ponds and 30,000 miles of rivers and streams, the waterways of the Adirondacks are enormous. Diverse aquatic habitats and ecosystems abound, along with bountiful recreational opportunities.  Nearly half of this land is owned by the state of New York and managed through the New York State Department of Environmental Conservation (DEC) as a forest preserve to return the wilderness to its “presettlement” state.
