Contactless flow sensor for large pipes

news item image
NIVUS is expanding its range of clamp-on sensors to include another variant that works on the basis of the ultrasonic transit time difference.
With its measuring frequency of 500 kHz, these sensors are suitable for large pipe diameters or for pipe wall materials.
The new sensors also work in pipes with wall thicknesses of up to 30 mm. Compared to the 1 MHz version that is also offered, the new version can detect higher flow velocities more efficiently.
Another advantage is the increased acoustic penetrability through the fluid. The signal is not so strongly attenuated, for example in the case of solids, gas bubbles or deposits on the inner wall of the pipe.
The clamp-on sensors are mounted on the pipe from the outside and measure without contact.
This eliminates the need for drilling or similar mechanical stresses on the pipe. An interruption of the process for installation or maintenance is also unnecessary.
The high degree of protection of the sensors according to IP68 enables their use even under the harshest conditions, for example, the sensors can be permanently buried in the.
Special polymer pads ensure a permanently reliable acoustic coupling between the sensor and the pipe.
NIVUS also provides robust and battery-operated transmitters for temporary or permanent use in harsh environmental conditions.
All systems allow for data access via an online measurement data portal.
