Flow meter for heavy duty industrial applications.


















Order code: 0695 0550 Cs Instrument

VA 550 - with M-Bus 

Flow sensor for heavy duty industrial applications incl. temperature measurement

Measuring range VA 550: 0.1...92,7 Nm/s, standard version* 0.1...185 Nm/s, max. version* 0.1...224 Nm/s, high speed version*

Accuracy: accuracy class (m.v.: of meas. value) (f.s.: of full scale) ± 1.5 % of m.v. ± 0.3 % of f.s. on request ± 1.0 % of m.v. ± 0.3 % of f.s. 

Accuracy indications referred to ambient temperature 22°C ± 2°C, system pressure 6 bar

Repeatability: 0.25 % of m.v. in case of correct mounting (mounting aid, position, inlet section)

Measuring principle: 7KHUPDOPDVVÀRZVHQVRUWKHPHDVXULQJHႇHFWLV based on the cooling down of a heated sensor PT 45 by bypassing gas. The ambient temperature is measured with a PT 100. An additional pressure and temperature compensation is not necessary
