6.1 PROCESS CHARACTERISTICS

Flow measurement
- Type of measurement
- Measuring range
- Linearity
- Repeatability
- Accuracy
(for M.V. from 1 to 10 m/s and -15 °C < medium T° with Stst. sensor < 130 °C
or 0 °C < medium T° with PVDF sensor < 80 °C)
* In the reference conditions, where: fluid = water, water and ambient temperatures = 20 °C,
upstream and downstream distances complied with, pipe dimensions adapted.
M.V. = measured value
