Due to the ultrasonic measurement technology, there is no need to calibrate the flowmeters to achieve the above stated accuracy. If you require calibration, this can be ordered for an additional charge. The certificate confirms that the supplied sensor and flowmeter combination is delivering measurements which are stated in the accuracy range. [...]
Calibrations for specific pipes are not necessary. Entering the specific application parameters (e. g. pipe diameter, pipe material, type of fluid) into the flowmeter ensures the above stated accuracy. If additional accuracy is required, a process calibration can be carried out on site.
Most of our flowmeters have a library of standard flowmeter programmed into them. If the liquid to be measured is not in the list there are two things that can be done: Choose Water from the menu. This might seem unhelpful, but water has a good average set of values for the three main [...]
The ultrasonic clamp-on sensors of the KATflow series come with a standard cable length of 2.5 or 5.0 meters depending on the specific sensor type. Additional extension cables of up to 100 meters can be ordered separately.
U-F-M | Katronic clamp-on ultrasonic flowmeters can cover a pipe diameter range from 10 mm (0.4 inches) to 3 m (118 inches). N.B. For non-standard applications we have special solutions available.
U-F-M | Katronic clamp-on ultrasonic flowmeters do not contain moving parts which could wear out. The sensor casings are manufactured from stainless steel and are not in contact with the flowing medium, which helps avoid corrosion. Therefore maintenance should not be necessary.
The ultrasonic sensors are simply clamped on the exterior pipe surface. This is how our flowmeters can be installed without the need to break into pipelines. The sensors are fixed to the pipe using metal chains, straps or mounting rails. Additionally, coupling paste is applied to the bottom of the sensors to ensure an [...]
For volumetric flow measurements, our flowmeters can achieve an uncertainty of 1 to 3 % of the measured value depending on the specific application. Uncertainty of approximately 0.5 % can be achieved with on-site process calibration. In case of flow velocity measurements, the flowmeters achieve an uncertainty within 0.5 % of the measured value. [...]
A clamp-on ultrasonic flowmeter is suitable for all commonly known pipe materials, whether ferrous, alloy or plastic. Ultrasound flowmeters also work on pipes with an inner lining, provided the pipe is acoustically conductive and there are no layers of air between the different pipe materials. Steel, stainless steel, asbestos cement, aluminum, copper, brass, lead, [...]
Clamp-on ultrasonic flowmeters can measure virtually all acoustically conductive fluids, regardless of their electrical conductivity. These include water, wastewater, beverages, oils, coolants, liquefied gases, and many process fluids. Only highly bubbly or highly viscous fluids can affect the measurement. In these cases, Doppler flowmeters or electromagnetic flowmeters offer a better alternative. Examples and more [...]
