Endress+Hauser prowirl 70 - Measuring Ranges Meter Bodies

Measuring Ranges
Meter Bodies
The following tables are given as
guideline for measuring ranges, vortex
frequency ranges and K-factors for a
typical gas (air at 0 °C and 1.013 bar)
and a typical liquid (water, at 20 °C).
Your E+H sales organisation will be
pleased to help you select and dimen-
sion a flowmeter for your specific
application.
