Wastewater Level Monitors
540 Technologies offers ultrasonic level sensors for remote monitoring of open channels, combined sewer overflows, storm drains, storage tank levels and flood warning systems. These non-contact sensors are non-contaminating and low maintenance. With their versatile telemetry options, robust construction and long battery life, they're ideal for remote or hard to access locations for “fit and forget” operations.
