The SU Puresonic sensor from ifm provides for accurate flow measurement of pure and ultrapure water. It detects water flow rates with high precision at volumes up to 1 000 l/min. Ultrasound technology enables this to be done also for ultrapure water with low conductivity, as produced in reverse osmosis plants. Thus, use of the SU Puresonic sensor in combination with conductivity sensors of the LDL family provides for reliable quality control in the filtration process.
The SU Puresonic is made of stainless steel, offering high media resistance and permanent ingress resistance.
The measuring pipe of the SU Puresonic is made of stainless steel and is free of measuring elements, seals and moving parts. This means faults caused by damage, leaks or blockages, which can occur in mechanical systems such as impellers or turbines, or, design-related pressure drops are excluded from the outset
Signal strength indicates process quality
Continuous monitoring of the signal strength enables the user to assess the quality of the medium or consider the need for maintenance. A declining value can be an indicator of an increase in particles in the medium, or deposits on the inner wall of the pipe. The signal strength is transmitted
a-cyclically via IO-Link and thus provides for maintenance work to be scheduled or the process sequence adjusted at an early stage. This ensures a high-quality end product.
The same functionality can be implemented for conventional systems that do not yet have IO-Link. If the signal strength falls below a predefined level, the device status will change and the sensor will signal this via the diagnostic output and the operating status LED.
The clearly visible operating status LED keeps the user on site always informed about the status of the sensor. The colouring corresponds to Namur Recommendation (NE) 107 for self-monitoring and diagnostics of field devices.
A simple plug and play system
Compared to clamp-on sensors, which need to be adjusted to the application depending on the installation situation, the SU Puresonic is a simple plug and play system: influencing factors such as varying wall thicknesses and pipe materials no longer need to be considered with the highly accurate inline measurement process. And there is no need for time-consuming programming or adjustments, which means a considerable amount of time is saved during implementation.
The stainless-steel measuring pipe ensures the SU Puresonic’s resistance to a variety of media and the compact design makes the ultrasonic sensor versatile and easy to use. The dimensions of the measuring and operating unit are kept narrow so that several sensors can easily be installed next to each other in a standard water manifold with a pitch of 50 mm.
In addition to the flow rate and the sensor status, the total flow rate and the temperature are also available via IO-Link.
