Process Flow

OSI's patented Optical Flow Sensors (OFS) can be utilized to monitor Air/Gas flow in a variety of applications where accurate flow measurements are critical. OFS technology is a very pure measurement and has zero effect from changes in temperature, pressure, gas densities, molecular weight or humidity.

You do not have to compensate the OFS measurement to anything!

OFS technology allows you to precisely measure air inflow to the combustion process for optimum combustion.

Why use OFS?
OFS technology allows you to monitor flows from .03-170 m/sec
OFS has the highest turndown 5000/1
OFS is Non-intrusive (nothing in the flow)
No interference/dependence on media composition. (hydrogen is not a problem)
No repiping required OFS can be installed as close as 2 diameters leading and 1 diameter trailing
OFS measurements are based on light fluctuations and not absolute light intensity
OFS can work in very difficult Flow applications weather other technologies struggle.
Laser Level

OSI has recently developed a Laser Level Meter. The LLM-100 is a compact industrial laser level sensor that utilizes an infrared laser and advanced micro-processor to measure levels in industrial storage tanks, large commercial process bins and agricultural silos.

The LLM controller is a simple substitute for a PLC or a laptop if one is not available. The LLM-100 will also work stand alone with RS485 (multi drop output) AND 4-20 ma output so if the user has a PLC or a laptop, they will not need the LLM controller.

The LLM head has a 4 line back lit LCD but due to where the LLM is installed, it may be hard to access. The LLM-100 controller will show the LCD display of up to 4 LLM Sensors as well as providing the power to them.

Do you have an application reach out and let us know how we can help.

OFS-2000, Optical Flow Sensor

The OFS-2000 has a range of 0-100 m/sec and is the only flow sensor that gives a true non-contracting cross-stack flow measurement of the process.
OFS Optical Flow Sensors for Wet Scrubbers, Bag Houses, and High Opacity

The OFS-2000W model is equipped with Automatic Gain Control (AGC) to compensate for variations in opacity caused by particulate matter or moisture carried in the flow.
OFS Optical Particulate Mass Flow Sensors

The OFS-2000P Particulate and Flow sensors report Air Flow and a general Particulate loading and percent opacity in virtually any operating condition.
LLM Laser Level Meters

OSI's patented Laser Level Meter (LLM) is a compact industrial sensor that utilizes an infrared laser and advanced micro-processor to measure levels in in industrial storage tanks, large commercial process bins and agricultural silos. The LLM-100 uses an eye safe pulsed infrared laser and measures distance using time of flight of a very narrow laser pulse. The sensor uses a very sensitive Avalanche Photodiode, which is coated with a bandpass filter to block out all ambient light. This enables the LLM-100 to be used indoors and outdoors on sunny days. The sensor can be used as a stand-alone sensor requiring only 12.5-36 VDC and out puts RS232 and 4-20 ma outputs or with optional control box.
