SCOTTSDALE, Ariz., January 23, 2009 — COX Instruments, a leading supplier of high-accuracy liquid and gas flow measurement solutions, has introduced a version of its LoFlo Series precision turbine flowmeter incorporating an integrally mounted COX 4080 flow computer. This flow measurement system provides enhanced accuracy and linearity in blending, batching, chemical injection and other demanding industrial applications.

The COX LoFlo Series turbine flowmeter is designed for measuring flows has low as 0.006 gallons-per-minute (GPM). The meter offers high accuracy, fast response to flow rate changes, and simplicity of construction with few parts. It is repeatable to +/-0.25% of reading, allowing for an overall accuracy of +/-0.5%.

The COX LoFlo Series turbine flowmeter can be paired with the COX 4080 flow computer to provide total flow compensation to enhance flow measurement accuracy, while linearizing over the full range of the flowmeter. Mounted directly to the meter or remotely, the COX 4080 allows for interchangeability without having to rescale the controller. It also utilizes an innovative “blade-averaging” technique to enhance low flow resolution.

In addition, the COX 4080 incorporates enhanced digital signal processing (DSP) technology allowing exceptional signal characterization and fast response to output dynamic data in engineering units. With this solution, end users can employ one device for multiple signal outputs; no external amplifiers or signal conditioners are necessary. Configurable interface software allows fluid selection, configuration of outputs, and data logging.
