The COSA Optical Flow Meter (OFM) uses laser beams to measure the gas flow by sensing the velocity of microscopic particulates naturally occurring in the gas.

The COSA Optical Flow Meter (OFM) has been specifically developed for gas applications with highly variable flow rates and a wide range of pipe diameters. The OFM accuracy is not affected by gas composition or contamination of the sensing elements.

The OFM uses laser beams to measure the gas flow by sensing the velocity of microscopic particulates naturally occurring in the gas.

Our OFM is compliant with ASME Code Section VIII, Division 1 and has been designed, manufactured, inspected and tested according to its recommendations.

The L2F consists of an optical head and a signal processing unit, which are connected by a fiber optic cable.

Optical Head:
An insertion-style optical head as shown in below figure is designed for use in pipes from 2 to 38 inches nominal bore. The optical system is incorporated in a 3/4” stainless steel sleeve, which is installed in the pipe in a similar manner as thermal dispersion mass flow meters. The stainless steel optical head incorporates the delivery and collecting optical system assemblies, which are positioned perpendicularly to the flange bore and are insulated from the gas by optical windows.


The optical head is typically designed for single-point measurement which is located in the center of the pipe or at a quarter-radius from the pipe wall.


Signal Processing Unit:
The signal processing unit ( or opto-electronic converter ) is designed on one electronic board which fits into a normal NEMA or an explosion proof enclosure. The board incorporates a digital signal processing (DSP) chip with internal analog-to-digital conversion at sample rates up to 12MHz. It has inputs for pressure and temperature transmitters, so that various flow calculations can be performed.

The 5200 Multi Purpose portable benchtop analyser provides an ideal solution for determining the composition of common gas mixtures in laboratories and light industrial applications.

  • Suitable for accurately measuring levels of oxygen and, from September 2005, carbon dioxide and carbon monoxide.
  • All sensors use non-depleting technologies, maximising availability and reducing maintenance and running costs.
  • Innovative construction gives a robust, single or dual measurement unit with space saving footprint.
  • A range of sampling and power options to meet individual user requirements.
  • Meets USFDA requirements for verification of medical oxygen USP and nitrogen NF.

Technology Used:

  • Oxygen – a choice of two Servomex paramagnetic transducers (standard or high accuracy), both offering fast, selective measurement of oxygen without the disadvantages of electrochemical or zirconia cells.
  • From September '05, Methane, carbon dioxide or carbon monoxide – Single beam, single wavelength infrared technology using Servomex's patented long life source gives a highly stable, selective and low maintenance measurement.


  • Paramagnetic and infrared sensors give reliable, credible results with low maintenance and running costs
  • Tower format saves space whilst offering dual measurement capability
  • Digital interface developed with customers to ensure desirable functions and ease of use
  • Reading available via backlit LCD display, RS 232 or optional mA output
  • Print individual readings (printer optional) or log up to 200 measurements and transfer them to a PC
  • User configurable concentration alarms and audible sounder
  • Power options include mains (100-240V AC), vehicle socket (12/24V DC) or advanced Lithium ion rechargeable batteries (8-36 hours use depending on sensors selected and use of pump)
  • Self monitoring software and Servomex support ensures user confidence

Typical Applications:

  • Laboratories and research
  • Air separation and gas bottling plants
  • Medical gas storage facilities
  • Physiology studies
  • Respiration studies
  • Douglas bag sampling
  • Diving centres
