  OWI-430-RH Present Weather Sensor
  OWI-430-RH - RH Option: A new advancement in accuracy

Our WIVIS intelligent algorithms are derived from study of 100’s of millions of hours of real - time data. With the -RH option, OWI-430 now integrates relative humidity measurement into this advanced weather identification system, resulting in:
enhanced discrimination of fog from dust/smoke
more precise haze and mist reporting
increased accuracy in precipitation measurements
elimination of false positive readings

  APG-815-DS  All - Precipitation Sensor

Performance advantages:

 Instantaneous precipitation rate measurement
 Rainfall as light as 0.1 mm/hr. or as heavy as > 500mm/hr easily measured
 No evaporation errors, overflow or mechanical limits to worry about
 No moving parts, no antifreeze chemicals
 Operates 24/7 under harsh field conditions
 Lower heater power requirements than heated tipping bucket rain gauge
 Dust / dirt on lenses does not affect measurement; ultra-low maintenance
 No sampling problems from wind. Slant path rain errors are negligible
 RS- 232 digital output allows instant / detailed analysis
 Intelligent sensor; automatic correction and continuous internal monitoring
 Flexible mounting, even on moving platforms (buoys / shipboard)
 Lasts for years
 Nominal 12VDC power

  OFS 2000R  Optical Flow Sensor - for Steam Lines
  OFS 2000R   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 and uses 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.
