CLAMP-ON ULTRASONIC FLOW METER FOR LIQUIDS WITH AIR BUBBLES OR SOLIDS

“Ultrasonic flow meters do not come into contact with the fluid at all. They are easy to install, commission and maintain. Installation requires no plant downtime. Ideal for both portable and fixed applications, line size has little influence on price.

The Greyline Clamp-on Ultrasonic Flow Meter is ideal for measuring flow in pipes where the liquid contains air bubbles or suspended solids.  The Doppler technology bounces ultrasonic waves off the air bubbles and solids and the electronics calculates volumetric flow.

The big advantage of the Greyline Doppler flow meter is that you simply strap the flow sensor onto the outside of the pipe.  So there is not down-time and no interruption of your process.  The meter does not come into contact with the liquid.  With no obstruction to flow, no pressure drop and almost no maintenance, the life-cycle cost of ownership is extremely low. 

The Greyline ultrasonic flow meter is available in a fixed configuration for permanent installations.  The portable version is supplied in a robust carrying case and it ideal for surveys, testing installed meters and temporary measurement.

Typical ultrasonic flow meter applications are aerated liquids, slurries, acids and pulp stock.  In fact, their best flow applications are those that would defeat regular contacting flow meters! The Greyline meter is suitable for pipes from 25mm to 4 500mm in diameter and flow velocities from 0.08m to 12.2m/sec. Accuracy is typically ±2%. For best operation the liquid should have solids or bubbles with a minimum size of 100 microns and minimum solids concentration of 75ppm.  There are hundreds of Greyline flow meters working in many industries in South Africa, especially on slurries and effluent.”
