Legal - Type approval of PARS-aqua Parshall Flumes

Our products were type approved on the 1st of July 1995 by the Czech metrology institute as a working measuring instrument for measurements of flow. This certificate of type approval is recognised within the countries of European Economic Area – EEA. The validity of the Type approval was prolonged on 22nd of June 2010 for another ten years. Another prolongation of the certificate is not needed as the type approval is not necessary for working measuring instruments according to the Czech Law on Metrology.
