CLAMP-ON DOPPLER – FLOW METER

Greyline Doppler Flow Meter for liquids containing bubbles, suspended solids or slurries.

Greyline Doppler Flow Meter

Ultrasonic Flow Meters - non-contact, non-invasive

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.

With no obstruction to flow, no pressure drop and no maintenance, the life-cycle cost of ownership is extremely low.

  • Portable flow meters are widely used for spot measurements or for checking the accuracy of existing flow meters.
  • Fixed meters are easy to install as they do not require any plant downtime or changes to existing piping.

Portable & Fixed

The Greyline non-intrusive flow meters measure flow from outside the pipe with a strap-on sensor. They are ideal for applications such as aerated liquids, slurries, acids and pulp stock. In fact, their best applications are those that would defeat regular contacting flow meters! 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.
