 Liquid density and viscosity: no restrictions Model CU100 Working principle The flowmeter model CU100 is an electronic device based on the transmission of ultrasonic signals through a pipe where liquid flows. This working principle is called “transit time”.  Ambient temperature: -20ºC ... +60ºC  Working pressure: no restrictions Two ultrasonic transducers, acting alternately as transmitterreceiver and properly installed on a pipe, send an ultrasonic signal, first in one direction (A→B) , then in reverse (B→A).  Connections: external mounting on pipe. Optional installation A digital...

Installation For an accurate flow measurement, the ultrasonic flowmeter model CU100 requires a straight pipe run of minimum 5 x DN before and after the flowmeter. The required distance depends on the flow profile, which can be affected by the disturbing elements found in the installation before and after the transducers, as shown in the following chart: Disturbing If the element is If the element is element before the CU100 alter the CU100 different planes In horizontal pipes, it is recommended to install the transducers on the sides of the pipe, and not on the upper and lower...
