A missing manual or missing pages must be replaced immediately if lost. The operating instructions can be requested at any time from VSE or downloaded from our website www.vse-flow.com. The operating instructions must be passed on to each subsequent user of the flow meter.
Performance of the flow meter depends on type, size and meter for a trouble-free and safe operation of the flow meters. Owing to range and on the liquid that is to be measured. Please consult VSE for the great number of various applications and flow meter versions, the an exact description..

The undersigned is liable for all damages which arise as a result of the non-marked decontamination of the returned flow meter. VSE expressly points out that repairs and verification work is carried out by trusting the correctness of the completion of this safety declaration (certificate of non-objection). Should physical injuries, death or even damage to property occur, claims for damages will be asserted.
