Katronic are specialised manufacturers of portable and fixed, ultrasonic clamp-on flowmeters and contactless level measurement equipment. Ultrasonic pulses pass through the pipe wall for a reliable, direct method of determining the physical properties of fluids. They measure the flow, level, concentration and density of liquids and liquefied gases. This technology benefits where the area surrounding the pipe is restricted, process hygiene must be maintained, the contents of the pipe are valuable, under high pressure or hazardous.
