6.4.26 Viscosity compensation (μ) setup (VISCOSITY COMP. (μ))
To determine error correction coefficients associated with fluid velocity and viscosity, parameters -
measurement units, under alarm point, over alarm point, viscosities 1 to 3, flowrate (frequencies) 1 to 9,
and meter errors 11 to 93 are set here.
※ These settings are used in Models EL4501 and EL4511.
Viscosity data: 3 points Fluid velocity data: 9 points max. Meter error data: 9×3 points max.
