Ultrasonic clamp-on flow measurement of liquids
Non-invasive, ultrasonic flow measurement is only an outsider method in the technical sense:
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.
The FLUXUS® H721 meters are Flexim’s Ultrasonic measuring systems for permanent installation designed for the hydrocarbon processing industry (HPI) - especially in the industrial environment. In addition to standard volume flow measurement, the H721 flowmeter has a number of additional functions and is available in different options. By combining the attributes of FLEXIM’s highly accurate and reliable non-intrusive ultrasonic flow measurement with temperature and, where necessary, pressure inputs, the integrated H721 meter is the ideal solution for hydrocarbon flow metering applications, where the fluid viscosity can significantly vary over the temperature range.
The H721 allows to report:
• Operational and standard (net) volume and mass flow
• Density, API number and Specific Gravity
• Sonic ID (for Interface Detection)
• Liquid ID (for Fluid Identification)
• Leak detection (data source based on multiple HPI flow meters)
Enclosed in a robust metal field housing, the FLUXUS® H721 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 FLUXUS® H721 meters produce stable and reliable measuring results even under the most difficult conditions.
