Clamp-on ultrasonic transducers are simply attached to the outside of the pipe. The practical advantages are obvious: no wear and tear by the medium, no risk of leakage, no pressure loss and, above all, constant plant availability.
The fact that non-invasive measurement technology could prove itself as a standard method in many areas of the industry, is, if nothing else, a credit to FLEXIM. Berlin‘s ultrasonic experts have repeatedly set new standards with their FLUXUS® flowmeters. Staffs at FLEXIM are particularly proud of the pioneering work carried out during the transfer of ultrasonic technology to non-invasive flow measurement of gases. FLEXIM is the only provider to carry out clamp-on ultrasonic flow measurements in high temperatures of up to 400 °C.
PIOX S722
The PIOX® S722 meters are Flexim’s Ultrasonic measuring systems for permanent installation designed for concentration analysis process control - especially in the industrial environment. In addition to the flow measurement, the S722 flowmeter has a number of additional functions to determine properties of the fluids and is available in different options. Its non-intrusive measurement technology ensures a precise bi-directional, highly dynamic flow measurement over a wide turndown ratio.
Enclosed in a robust metal field housing, the PIOX® S722 meters are completely water-tight and designed for usage in rough environments. As the transducers are mounted on the outside of the pipe wall in rugged VARIOFIX mounting fixtures, the system does not suffer from wear and tear or clogging, can't be a risk for leaks and will not cause any pressure drops inside the pipe.
Due to their matched and paired transducers as well as the internal temperature compensation (compliant to ANSI/ASME regulations), the measurement system is drift free and zero stable ensuring accurate readings. Moreover, as the transducer calibration data is automatically loaded by connecting the transducer to the transmitter the set-up times are significantly reduced. As of its exceptional dual-uP technology, the high number of measuring cycles per second and the adaptive signal processing, the PIOX® S721 meters produce stable and reliable measuring results even under the most difficult conditions.
• Non-intrusive liquid metering - Installation without process interruption or production stop
• Virtually maintenance free due to permanent coupling pads and rugged mounting fixtures
• Low installation and operation costs (independent of pipe pressure and size)
• Highly accurate, reliable and stable measuring results even under difficult conditions
• Versatile electrical inputs and outputs for the optimal adaptation to the individual application needs
• Ideal solution for the measurement of aggressive, corrosive or toxic media in hazardous areas ( FM Class I, Div. II / ATEX/IECEx Zone 2, EAC TR TS Zone 2, INMETRO Zone 2 version available)
• Exhaustive internal database with complete parameter set of a variety pipe materials and media
• Ideal solution to determine the concentration or other properties. Together with the volume flow and a temperature measurement a mass flow calculation of the liquid will be offered.
