Measure flow without obstacles: The SU Puresonic Ultrasonic Sensor

  • Precise flow measurement of ultrapure water and water
  • Robust, component-free measuring tube made of stainless steel offers high media resistance and permanent tightness
  • Operating status LED signals sensor status according to Namur NE107
  • Output of signal strength enables conclusions to be drawn about process quality
  • Precise measurement data even with ultrapure water

The SU Puresonic detects water flow rates with high precision at volumes of up to 1000 l / min. Thanks to ultrasonic technology, this also applies to ultra-pure water with low conductivity, such as that produced in reverse osmosis plants. In combination with the conductivity sensors of the LDL family, reliable quality control can be established there in the filtration process.
The measuring tube of the SU Puresonic is made of stainless steel and is free of measuring elements, seals and moving parts. This means that errors caused by damage, leaks or blockages, which can occur in mechanical systems such as impellers or turbines, are excluded from the outset, as is the pressure drop caused by the design.

Signal strength as a quality and maintenance indicator
The continuously recorded signal strength enables conclusions to be drawn about the quality of the medium or the need for maintenance. If the value drops, this can be an indicator of an increase in particles in the medium or deposits on the inner wall of the pipe. The signal strength transmitted acyclically via IO-Link thus enables the user to schedule maintenance work or adjust the process sequence at an early stage. In this way, high quality of the end product can be ensured. This function is also implemented for conventional systems that do not yet have IO-Link. If the signal strength falls below a predefined level, the device status changes and the sensor signals this via the diagnostic output and the operating status LED.
