• OFS 2000F for Flare Gas

• OFS 2000 for Air Assisted Flare

• OFS 2000R for Steam Assisted Flare

Meets or exceeds EPA, SCAQMD  and EU requirements

AWOS Systems • HazMet 100 • OFS 2000

OFS 2000 Optical Flow Sensor

Air/ Gas/ Steam Velocity with Mass/ Volumetric Flow

Non-Intrusive

No direct contact with flow media. Immune to the effects of temperature, gas density, moisture content, particulate count, or pressure. If OFS 2000 can detect turbulence-induced fluctuations with even a fraction of the light, it can accurately measure the flow velocity. It is, in this sense, a “pure” measurement.

AWOS Systems • HazMet 100 • OFS 2000

OFS 2000 Optical Flow Sensor

Air/ Gas/ Steam Velocity with Mass/ Volumetric Flow

No Calibration Required

Using scintillation as a basis of measurement means the all-digital / DSP-based OFS 2000 systems require no calibration – ever. Our patented process is supported with over 20 million hours of observation data, and certified by NIST (National Institute of Standards.) Automatic calibration check along with continuous self-test diagnostics are built-in for user security.

AWOS Systems • HazMet 100 • OFS 2000

OFS 2000 Optical Flow Sensor

Air/ Gas/ Steam Velocity with Mass/ Volumetric Flow

Full-Path Averaging

OFS 2000 provides a dynamic velocity measurement of the passage of gas or air through a light beam averaged directly across the entire volume. Scintillation through the entire path is detected, analyzed, calculated, and reported - a much more representative measurement than single point or slanted path.

OFS 2000 Optical Flow Sensor

Air/ Gas/ Steam Velocity with Mass/ Volumetric Flow

Flexible Installation

OFS can install in tight spaces with minimum space requirements of 2 upstream / 1 downstream diameters. No re-piping needed. Installation is to standard ANSI pattern 4” pipe flange. OFS can be installed on live process pipes using hot tap procedure and gate valves for isolation.

No shutdown or interruption required.

All systems are equipped with analog current loop / digital data outputs, and can be configured with Serial port, Limited Distance Modem, and Fiber Optic Interface for any type of WAN or LAN.

AWOS Systems • HazMet 100 • OFS 2000

OFS 2000 Optical Flow Sensor

Air/ Gas/ Steam Velocity with Mass/ Volumetric Flow

No Moving Parts

OFS 2000 is essentially maintenance-free, save for window cleaning. OFS internal monitoring alerts the user if window cleaning is required. (Typically only semi-annually (if then) on the dirtiest stack and duct applications.)
