Measuring level with non-contacting ultrasonics

The latest Siemens range of ultrasonic transducers for level measurement is delivering accurate and reliable measurement to the water industry.

The latest Siemens range of ultrasonic transducers for level measurement is delivering accurate and reliable measurement to the water industry. For most level measurement applications in the environmental industries, ultrasonic technology is a highly desirable solution. Ultrasonic sensors (transducers) emit acoustic pulses and receive an echo from the material being measured.

The sensor is connected to a transceiver that calculates level by processing the time between the original signal and its echo.

Siemens Echomax transducers are built to provide accurate, reliable measurement even in harsh and hazardous environments.

They're impervious to dust, moisture, corrosion, vibration, flooding and temperature extremes.

Siemens ultrasonic transceivers feature Advanced Sonic Intelligence echo-processing capabilities to ensure reliable data even in conditions with obstructions, turbulence and foam.

The transducers also have an integral temperature sensor to compensate for sound velocity variations caused by changes in air temperature.

Siemens transducers are easy to install, and the non-contacting design makes them low maintenance by avoiding the corrosion, material build-up, and general wear and tear associated with contacting devices.

Higher maintenance costs and repairs associated with contacting devices can easily exceed any initial savings.

The Echomax device has become the preferred choice in a wide range of applications including wet wells, weirs and flumes, storage tanks, penstock and sluice gate control, and rake screens.
