STACK INDUSTRY is a leading ultrasonic level sensor manufacturer and supplier, delivering state-of-the-art non-contact measurement solutions. Our ultrasonic sensors utilize high-frequency sound pulses to accurately detect level heights in tanks, silos, and open channels. By timing the "time-of-flight" of the echo, our sensors provide precise data without ever touching the process medium, making them ideal for corrosive or hazardous liquids.
As a trusted industrial supplier, we offer a variety of sensing ranges—from compact 1-meter and 2-meter models for small containers to heavy-duty variants capable of measuring up to 15 meters. Our sensors are designed for easy integration with existing automation systems via 4-20mA, 0-10VDC, or RS-485 Modbus communications.

Our ultrasonic level sensors are ideally suited for a wide range of industries including water treatment, food and beverage, chemical processing, oil and gas, and pharmaceuticals. They are commonly used for:
The sensor emits high-frequency sound waves that bounce off the surface of the medium. The device measures the time it takes for the echo to return (Time-of-Flight) and calculates the distance to the surface, which is then converted into a level or volume reading.
Yes, ultrasonic sensors are versatile and can measure the level of liquids, powders, and granular solids. However, for very dusty environments or low-density solids, specialized tuning or high-power models may be required.
Non-contact measurement eliminates maintenance needs related to mechanical wear and prevents contamination of the process medium. It is perfect for corrosive, viscous, or sterile liquids where traditional probes would fail.
Dense foam can absorb sound waves, potentially leading to inaccurate readings or signal loss. In applications with heavy foam, we recommend using our radar level sensors or hydrostatic pressure transmitters for higher reliability.
