OPERATING PRINCIPLE

The EC80 Flow Processor accepts all types of square wave pulse inputs Fully

compensated and linearized volumetric flow rates, totals and temperature are

examples of flow parameters that can be viewed through serial communications,

included software program or an embedded rate indicator (depending on

product configuration)
The EC80 Flow Processor can use a universal viscosity curve to compensate for

varying liquid temperature and viscosity conditions It can also use

Strouhal-Roshko algorithms for a more comprehensive compensation method,

taking into consideration all the secondary effects to which the meter is sensitive

like the expansion and contraction of the meter bore diameter The flow processor

extracts the density value of a known liquid from a stored temperature/density

table and multiplies by the volumetric flow rate to get the inferred mass flow rate
