Kobold has developed the innovative DUK device range for flow measurement of low-viscosity liquids. These devices work following the principle of ultrasonic time-of-flight measurement and can not only measure and monitor but also count and measure out.
The six different connection sizes from ½ to 3 inches are particularly practical as G or NPT threads. As a result, the flow measurement ranges are from 0.08-20 L/min to 2.5-630 L/min, with which almost any measurement task can be performed. The enormous measuring span of 1:250 of each measuring range offers the greatest possible flexibility and is a major advantage over other measuring systems.
In addition to the standard brass version, a resistant stainless-steel version is available for measuring aggressive media. The extremely low pressure loss and the option of individually adjustable flow directions enable application even on complex pipe connections. Process conditions of up to 16 bar and 120 °C are well tolerated by the ultrasonic flowmeter making it universally applicable across all industries.
The devices can be equipped with a switch, frequency or analogue output for practical data processing. Sophisticated compact electronics that includes a digital display, and a switch and analogue output are also offered. The device range is topped off by dosing and counting electronics available as an option. The counting electronics displays the current flow amount and the partial or total amount simultaneously. Dosing electronics controls simple filling tasks and also measures the flow amount, total amount and filling amount. The analogue output and two relay outputs can be used for signal processing
Thanks to this variety of electrical evaluation options, the right version for everyone is available, from the cost-effective solution to the most elaborate solution.
The company Kobold Messring GmbH has developed an all-rounder with the DUK ultrasonic flowmeter which stands out thanks to its high quality, great flexibility and breadth of measuring range.
