Ultrasonic flow meter 280CiRN

In the laminar and transition flow regimes, measuring oils with high viscosity and/or low flow conditions may necessitate working at Reynolds numbers below 10,000. Because the liquid velocity profile irregularly flips between laminar and turbulent features, the performance of full-bore ultrasonic flow meters has historically decreased for Reynolds values below 10,000. The eight-path reduced nozzle liquid ultrasonic flowmeter from CALDON LEFM 280CiRN Series features a reduced bore design modeled after flow nozzle technology, in which the liquid velocity profile is stabilized in the throat by forces significantly greater than the forces imposed by fluid viscosity. Under all operating situations, the meter stabilizes the flow profile while avoiding boundary layer separation, considerably enhancing performance.

Ultrasonic flow meter 280CiRN signals are magnified in the direction of flow but delayed in the opposite direction as soon as the fluid in the tube begins to flow. The flow rate is proportional to the difference in transit times between the two sensors. An ultrasonic flow meter that requires particles or bubbles in the flow is an ultrasonic flow meter (non-intrusive Doppler flow meters). Ultrasonic meters are appropriate for wastewater applications or any conductive or water-based unclean liquid. Doppler flow meters are often ineffective when used with distilled or drinking water. Clean liquid applications would need aeration. Ultrasonic flow sensors are also suitable for applications requiring minimal pressure drop, chemical compatibility, and low maintenance.The flow volume of a wide range of gases and liquids may be measured reliably using ultrasonic waves — regardless of electrical conductivity, pressure, temperature, or viscosity. Inline ultrasonic sensors are ideal for usage in applications that demand traceable and assured accuracy. Clamp-on ultrasonic sensors, on the other hand, are mounted on the pipe’s outside wall, allowing for temporary measurements or retrofitting.
