How It Works: Measuring Principle
The fluid flows through a continuous pipe containing two low pressure drop static mixers.
The sensor device measures the pressure drop at both static mixers by means of two differential pressure measurements: ∆P1 and ∆P2.
Pipe flow rate is required to accurately determine the flow regime to which the viscosity is to be calculated. Pipe flow rate can be obtained from either an external data measurement or with a flow meter. Flow rate measurement is not integrated in the Viscoline.
From the two pressure drop measurements and the flow rate reading, the fluid flow parameters are processed in the system, and the pipe line viscosity is determined. A temperature reading can be useful for thermal correction, when a reference measurement is required. Such correction requires laboratory thermal characterization or dual measurement.
