Ultrasonic Level Transmitters
Ultrasonic level transmitters provide reliable, non-contact measurement of liquid and bulk solid levels in a wide range of industrial applications. These devices operate by emitting ultrasonic sound pulses toward the surface of the measured material and calculating level based on the time it takes for the reflected signal to return. Because the sensor does not come into direct contact with the process material, ultrasonic level transmitters help reduce contamination risk and minimize sensor wear in demanding environments.
These instruments are commonly used in open channels, tanks, silos, and reservoirs where continuous level monitoring is required. Ultrasonic level transmitters are particularly well suited for corrosive, polluted, or abrasive applications where contact-based measurement technologies may fail or require frequent maintenance. Their accuracy is directly related to precise time-of-flight measurement, making them dependable solutions for level detection and control in industrial processes.
Ultrasonic level transmitters are also valued for their versatility and ease of integration. Many models offer configurable outputs and signal options to match system requirements, allowing seamless communication with PLCs, controllers, and monitoring systems. With durable construction and straightforward installation, ultrasonic level transmitters provide a practical balance of performance, reliability, and cost efficiency for continuous level measurement.
FAQs
Q: How do ultrasonic level transmitters work?
Ultrasonic level transmitters emit sound waves toward a material’s surface and measure the time it takes for the echo to return. This time is used to calculate the distance, which corresponds to the level.
Q: Are ultrasonic level transmitters suitable for non-contact measurement?
Yes. Ultrasonic level transmitters measure level without contacting the material, making them ideal for corrosive, dirty, or hazardous environments.
Q: Can ultrasonic level sensors be used with bulk solids?
Yes. Ultrasonic level sensors can measure bulk solids and can be used to calculate volume when combined with the known dimensions of the storage container.
Q: What affects the performance of an ultrasonic level transmitter?
Performance depends on factors such as transducer quality, signal cone angle, surface conditions of the material, and environmental factors like temperature or heavy vapor.
Q: What is the difference between a transmitter and a transducer?
A transmitter sends a standardized current signal, such as 4–20 mA, while a transducer sends a voltage signal. Transmitters are better suited for longer distances and environments with electrical noise.
