Laser Accurately Measures Highly-Reflective Liquids

Hawk Measurement Systems, OptioLaser S300 is highly capable for the detection of all types of liquids, regardless of their dielectric properties. The laser can accurately and reliably measure highly reflective liquids, clear liquids, and turbulence liquids. Due to its narrow beam divergence, it can be used to measure through grates and narrow passages, and next to flat walls.


OptioLaser S300 lasers are user configurable, allowing optimal performance of your specific application. It uses an infrared, low-gain GaAs laser diode, light energy of 905 nm that travels to the surface of any liquid and is reflected. This time-off-light (the time the laser pulse took to travel to the liquid and back) is then calculated into a distance. The low-gain diode allows for accurate measurement of even highly reflective, clear liquids- regardless of the dielectric properties. Summary of features include:
