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.

Cal Poly, San Luis Obispo Manages Monitoring Efforts in Morro Bay
California Polytechnic State University, San Luis Obispo (Cal Poly, SLO), has been monitoring Morro Bay for decades, and while the monitoring program has changed over the years, the dedication to monitoring the bay has remained the same. 
 
The project started in 2006 as a Packard Foundation-funded initiative to monitor water quality flowing in and out of Morro Bay. The goal at the time was to use the data collected to develop and inform an ecosystem-based management plan in collaboration with the Morro Bay National Estuary Program (MBNEP). 
 
Since the estuary was the focus at the time, researchers were monitoring water flowing into the estuary from Chorro Creek and Los Osos Creek.

While the bay of Green Bay has been referred to as the largest freshwater “estuary” in the world, the watershed hosts intensive agriculture and contributes one-third of Lake Michigan’s total phosphorus load. 
 
 The Fox River flows into the bay, carrying excess nutrients largely the result of non-point source runoff from the watershed. With a history of deterioration extending well into the last century, the bay ecosystem suffered significant declines in water quality. 
 
 This, in turn, stimulated major clean-up and ongoing restoration efforts to improve water quality. Tracking these changes is an important aspect of ecosystem management.

The Tijuana River runs across the US-Mexico boundary, flowing into and throughout southern California, carrying with it nutrients and contaminants throughout the estuary. In recent decades, the flows have been heavily polluted with untreated sewage from the City of Tijuana. 
 
The wastewater enters the greater Tijuana River estuary, impacting coastal communities and disrupting the natural environment. In order to better understand these cross-border flows, researchers out of San Diego University sought to monitor the waterway test the capabilities of in-situ sensors to measure the contaminated water. 
 
Natalie Mladenov and Trent Biggs were two of the researchers involved in the project, deploying a real-time monitoring system in May of 2021.
