The ULM-70 ultrasonic level meter is designed for continuous and precise level monitoring in industrial storage tanks, reservoirs, and process vessels. Using advanced ultrasonic technology, the sensor measures the distance between the transmitter and the product surface without physical contact. This makes it ideal for applications involving liquids, slurries, pasty substances, and certain bulk solids where durability, reliability, and minimal maintenance are essential.
Industries such as water treatment, chemical manufacturing, food processing, and wastewater management require dependable level monitoring solutions. The ULM-70 ultrasonic transmitter delivers stable measurement performance even in demanding environments. Its intelligent signal processing filters false echoes caused by tank structures such as ladders, mixers, and reinforcements, ensuring accurate measurement data for process control systems.

- Optional explosion-proof version for hazardous environments
These features make the device suitable for demanding industrial measurement applications where reliability and stability are critical.
Design & Functionality
The ultrasonic transmitter emits high-frequency acoustic pulses toward the product surface inside the tank. The pulses reflect back to the sensor and the system calculates the level based on the time required for the signal to return. Advanced digital signal processing compares the received echo with stored interference patterns, allowing the instrument to ignore false reflections and focus only on the correct surface signal.
The robust housing and industrial mounting options allow easy installation in tanks, vessels, open channels, or sumps. The device also supports adjustable damping and measurement intervals, enabling stable readings even in turbulent process conditions.
Total Crossed Beams
The ultrasonic beam geometry is optimized to provide stable reflections from the material surface while minimizing interference from surrounding structures. Directional beam control allows accurate detection even when tanks contain mixers or structural obstacles. The controlled beam pattern ensures precise measurement performance in both open and closed containers.
Beam Pitch Options
Different measurement range versions are available to support multiple tank sizes and industrial applications. Depending on the selected model, the sensor can measure levels from small vessels to large storage tanks. This flexibility makes the instrument suitable for water treatment plants, chemical storage systems, and bulk material silos.
Intrinsic Synchronism
Advanced digital processing ensures synchronized pulse transmission and echo detection. This intrinsic synchronism improves signal stability, reduces measurement noise, and enhances long-term accuracy. The integrated electronics also compensate for environmental conditions such as temperature variations inside tanks.
Operational Advantages
Industrial operators benefit from stable level measurement, reduced maintenance, and reliable integration into automation systems. The non-contact measuring principle eliminates sensor wear caused by aggressive chemicals, pressure, or mechanical contact.
The ULM-70 ultrasonic level transmitter provides accurate monitoring for:
- Industrial storage tanks
- Wastewater treatment reservoirs
- Chemical processing vessels
- Bulk material containers
- Water management systems
With its robust construction and intelligent signal evaluation, the device delivers consistent measurement performance for modern industrial process control.
