Product Overview
BBULM-T uses non-contact ultrasonic technology to measure the distance between a top-mounted sensor and the surface of a liquid or bulk solid. The measured distance can be converted into level, material level, or distance data. It is suitable for water and wastewater treatment, agricultural irrigation, industrial tanks, and bulk materials such as cement and plaster.
Integrated and split configurations are available. Measurement data can be viewed locally and transmitted to telemetry, remote monitoring, and automation systems.
