Lauris FF1225-A Inline Ultrasonic Gas Flow Meter

Transit-time metering with no moving parts and almost no pressure loss.

A single-path axial transit-time ultrasonic gas flow meter with two transducers, no moving parts and very low pressure loss, built for wet, dirty and variable gas — flare, vent, flue, fuel and process streams. Made by Lauris Technologies in Canada.

ACTS is Blue Dragon Technology’s sole agent in Egypt, supplying the Lauris FF1225-A Single-Path Inline Ultrasonic Gas Flow Meter to oil & gas, petrochemical and power generation plants nationwide from our office in Sheikh Zayed City, Giza. Sizing and selection are handled by our own application engineers, with aftermarket support and technical services once the unit is in service.

Key Features
  • Axial single path, two transducers
  • Online-retractable transducers
  • Measures standard and actual flow, totals, molar mass, P and T
  • Two 4–20 mA inputs for pressure and temperature
  • Up to twelve 4–20 mA outputs optional
Engineering Benefits
No moving parts and no obstruction, so wet or dirty gas does not cost accuracy
Retractable transducers are serviceable without breaking the line
