Optical Scientific Inc Announces Optical Flow Sensor Developments

Optical Scientific Inc (OSI) has announced developments made to its advanced line of optical flow sensors (OFS).

The company is a leading manufacturer of optical flow measurement sensors for emissions monitoring and process control applications in a wide variety of industries.

All OFS models now include the MODBUS RTU Over Serial Interface mode in addition to RS-232C Serial I/O and 4-20mA Current Loop interfaces. From the beginning of this year, all models have this feature. Note that earlier models can be easily updated with a simple firmware update that can be easily done in the field in just minutes.

Next, all models include an enhanced interface board that allows the sensor to input data from each smart temperature and pressure sensors by means of two new 4-20mA current loop inputs. This allows the sensor to calculate and report volumetric flow instead of just velocity (and mass flow if a plug-in constant is entered.) This data is not needed by the sensor to provide extremely accurate flow measurement; it’s simply an add-on since some of our customers prefer volumetric reporting instead of velocity reporting.

All models now have this feature and earlier models can be upgraded by swapping the original interface board and updating the firmware, both of which are easily done in the field.

OSi maintains a long-time corporate practice of continual product improvement, hand-in-hand with backwards compatibility and careful configuration control.  Our sensors are some of the best available.
