Reliable Level Measurement
The Hach BL9000 Bubbler Level Sensor is a reliable solution that uses a simple tubing and bubble pressure system to determine level and depth measurements. The BL9000 provides accurate and stable level measurements and, unlike traditional level sensors, requires no external air pump, reducing complexity and maintenance needs while ensuring continuous performance. Equipped with a self-purging function that prevents clogging and debris buildup, this system minimizes maintenance while maintaining long-term accuracy in environmental challenges such as steam, foam, high temperatures, and reverse flow – all of which won’t impact the BL9000’s ability to deliver precise measurements.
Designed for measuring liquid levels in municipal and industrial flow monitoring applications, it seamlessly integrates with the Hach FL1500 Flow Logger and the Hach FL900 Ultrasonic Flow Logger.
