Optical Density Meter for Control

McNab, Incorporated announces an electronic optical density monitor and controller for process control. The McNab Model HSA 1 uses optical sensors and a solid-state indicator controller.  The indicator controller has two alarm points, with output relays to signal when product quality is unacceptable.  The sensors mount on the McNab Model HSA 1 integrated flow cell system.  Materials of construction are stainless steel with rugged glass lenses.

The optical sensors measure turbidity or clarity of the process across the pipe.  Pipe sizes up to 8 inches can be provided. The in-line, full-time, measuring system operates at line pressure up to 150 PSI, and does not require a by-pass line or other sampling or cooling systems. The unit utilizes the McNab flow cell system, developed over 25 years for reliable measurement of in-pipe process fluids.

The Model HSA 1 is useful for measuring concentration levels and fluids that must have fillers added to meet specifications.

McNab also manufactures conductivity, salinity, pH, and specific ion monitors, including models that feature built-in chart recorders.

For additional information on the McNab Model HSA 1 or any McNab analyzer/controller, contact McNab.
