Introduction to flow range of Supmea vortex flowmeter

Project Overview

The measuring flow range of vortex flowmeters with different calibers will be different, so during the selection process, the instrument must be selected according to the flow range. Never take it for granted that the flowmeter is selected according to the thickness of the pipe. Otherwise, it is likely that the on-site flow rate is not within the measurable range of the vortex flowmeter, resulting in measurement errors.

The table in the figure below lists the measurement ranges of DN15~DN300 pipeline vortex flowmeters. It can be seen that the measurement ranges of liquid and gas vortex flowmeters of the same caliber are also different. The medium conditions for this flow range are as follows:

1. Gas: air at normal temperature and pressure, t=20℃, P=0.1MPa (absolute pressure), ρ=1.205 kg/m3, υ=15×10-6 m2/s.

2. Liquid: normal temperature water, t=20℃, ρ=998.2kg/m3, υ=1.006×10-6m2/s.
