Focus® 2.0 Optical Gas Flow Meter

An advanced cost effective system for gas velocity and volumetric flow rate measurements independent of pressure, temperature and gas composition.

The systems principal technology, Laser-2- Focus Velocimetry, uses laser beams to measure the gas flow by sensing the velocity of microscopic particulates naturally occurring in gas. The Focus 2.0 system consists of flow sensor, an optical flow processor and a heater power supply. The system includes the new user-friendly software with a Wizard mode that enables and easy step-by-step configuration of parameters.

Easily installed and maintained in the field, the system requires only one installation point in the gas line and takes less then 3 hours to install under normal conditions without interrupting site operations or entire system shutdown. The Focus 2.0 is used at accurately measure a wide range of flow rates in a variety if pipe diameters (4” – 36” Inches).
