Focus® 2.0 Optical Gas Flow Meter
The Focus 2.0 Optical Gas Flow Meter from Kings Energy is an optical flow meter that measures gas flow by using lasers to detect the velocity of microscopic particulates in the gas stream. It offers accurate gas velocity and volumetric flow measurements that are largely independent of pressure, temperature, or gas composition, making it well-suited for challenging applications like flare gas, vent gas, or biogas flow measurement.
Features
Employs advanced Laser-2-Focus technology for optical flow measurement, replacing conventional pressure and thermal methods.
Delivers a high turndown ratio, enabling detection across a wide range of flow rates.
Maintains reliable performance regardless of variations in gas composition, pressure, or temperature.
Offers non-intrusive measurement with minimal flow blockage and low pressure drop.
Supports installation in large pipe diameters (4 - 30 in)
Integrates easily with multiple output and communication interfaces, including analog 4-20 mA for flow/velocity, RS-485 with MODBUS, frequency pulse output, and optional inputs for pressure or temperature.
Designed for simple installation and maintenance, the sensor requires only a single insertion point and can often be installed without process shutdown.
