Krohne Vortex flowmeter – OPTISWIRL 4200
Vortex flowmeter - suitable for measuring various media
Vortex flowmeter - suitable for measuring various media
It can measure conductive and non-conductive liquids and a variety of industrial gases. It also measures saturated and superheated steam, compressed air and nitrogen, liquefied natural gas and flue gas, demineralized water, boiler feed water, solvents and heat transfer oils.
Vortex flowmeter – OPTISWIRL 4200
Vortex flowmeters are suitable for wide range measurements. This is especially true of the OPTISWIRL 4200. Ideal measurements for process control or energy supply even under fluctuating pressure and temperature conditions.
The basic OPTISWIRL 4200 already has the function of temperature compensation for saturated steam. The OPTISWIRL4200 with optional pressure sensor integrates density compensation, so it can accurately measure the flow of gas and superheated steam in industrial processes. The additional integrated gross and net heat measurement functions make the OPTISWIRL 4200 a reliable partner for advanced energy management systems.

Measurement principle
Vortex flowmeters are used to measure the flow rates of gases, vapors and liquids in pipes. The measuring principle is based on the Karman vortex street. The measuring tube contains a generator behind which a vortex is created. The frequency f of the vortex street is proportional to the flow velocity v. The dimensionless Strouhal coefficient S describes the relationship between the frequency f(Hz) of the vortex street, the width b of the vortex street and the average velocity V(m/s):
f=S*v/b
in:
f: Vortex frequency
v: average flow velocity
S: Strouhal coefficient
b: width of vortex generating body
The frequency of vortex occurrence is collected by the sensor and calculated by the converter.
