The WL900 Radar Level Transmitters offer a logical extension to ultrasonic devices, where application conditions are in need of non-contact liquid level measurement, but ultrasonic level transmitter measurement are not acceptable. The WL900 Radar Level Transmitters are ideal for a variety of water and wastewater applications where you have a reflective liquid that has a foaming surface, vapors, or dusty conditions beyond ultrasonic transmitter capabilities. The Radar Level Transmitters are also unaffected by temperature, vacuums, pressure, methane, or CO2.

  • Overview

    The WL900 Radar Level Transmitters use state-of-the-art radar pulse technology which provide accurate and reliable level measurements over their wide 10 inch to 50 foot range. With their simple push-button calibration system, the WL900 Radar Level Transmitters are easy to set up and maintain on the bench or in the field by following simple instructions. Simply aim the WL900 Radar Level Transmitters at your low range level set point and push the button to lock in the setting - do the same with the high level set point. This may be done before permanently installing the Radar Level Transmitter by aiming the instrument at a wall and using a tape measure to determine your exact range.

    Key Features:

    • Accurate, non-contact measurement
    • Works in conditions where ultrasonic is not acceptable
    • Pulse radar measurement range 10” to 50’
    • Simple push-button calibration
    • Standard 4-20mA signal output with optional RS485 digital output

    The WL900 Radar Level Transmitter's rugged NEMA 4 (IP65) housing is available in either aluminum or 316L stainless steel for corrosive environments. A standard 2 inch NPT (M) process connection allows for quick and versatile installation of the Radar Level Transmitter. The Radar Level Transmitter's polypropylene antenna rod is virtually corrosion proof

  • FAQs

    What makes the WL900 different from other YSI water level instruments?

    The WL900 is a noncontact Water level sensor that uses Ultra Magnetic waves to measure water depths. This particular sensor is analog instead of digital and uses 4-20mA outputs.

    What applications is the WL900 best suited for

    Ideal for bridges, tanks, flumes, weirs, and hydrological dams that primarily come in contact with vapor, foam, steam, dust, or powder. 

    How will I know water depth and water level detection?

    The WL900 records the depth from a signal and then the data is recorded in a datalogger or transferred directly to your monitoring device. 

    What type of water depths can I read?

    The WL900 can read between 10’ to 50’ depths

    What is the difference between radar level sensors and ultrasonic sensors.

    Both sensors excel at detecting water level for bridges, tanks, flumes, weirs, and hydrological dams, but it’s the conditions within those places that make all the difference.

    Ultrasonic sensors are lower cost, can have high-quality performance and longevity, however they thrive in a straightforward environment with no additional outside interferences for the sonic waves to bounce off of such as vapor, foam, steam, dust, or powder.

    Radar level sensors are higher cost but have the added benefit of being able to detect water level in environments that include vapor, foam, steam, dust, or powder.

    Simply put Ultrasonic sensors are best utilized where water conditions are closed and the sensor is only in contact with the water where Radar level sensors can be in open and closed environments where water particulates and inferences can be an issue.
