OSI Announces Enhancements – And a New Model

Nearly 20 years ago, OSI developed an original approach to determining air/gas velocity by applying our patented scintillometry technology. The result: the OFS 2000 line of optical flow sensors now employed world-wide wherever a tough, dependable, precision instrument is needed. OFS 2000 systems have proven excellence in cost-effectiveness in refineries, power plants, incinerators, chemical plants, paper mills, and mining operations - in every sort of industrial application where environmental compliance or superior efficiency is required.


  • OSI now offers the “E” option. Any OFS model can be optionally configured with the ability to accept smart temperature and pressure sensor current loop data to calculate and report volumetric flow or mass flow in addition to velocity. Model designations have an “E” added: OFS 2000E, 2000FE, 2000WE.

  • In addition, all OFS 2000 models now have MODBUS RTU, enabling network communication along with the standard RS-232 and 4-20 mA outputs. Adapters for RS-485 and Ethernet are also supplied at customer request.


These options can be retrofitted to existing sensors in the field, or at our facility.

OFS-2000R for Steam Line Flow Measurement

OSI has expanded OFS technology from simple air/gas flow to include measurement of industrial steam lines.


The OFS-2000R utilizes the extended range of our “F” model with AGC to optimize the amount of light based on the level of steam in the line. Measurement is not dependent on differential pressure, design DP, beta ratio, temperature, gas composition, humidity or the speed of sound.
