A high capacity helical vane (Woltmann) type water meterFC model for cold water up to 50°CIt has the advantage that the measuring element may be quickly removed and replaced on-sitewith a precalibrated measuring mechanismNo gears in the wet area; only one moving part - the impeller - in contact with waterIt can be installed in horizontal, vertical or inclined pipelines without any loss of accuracyA bold seven figure, straight reading counter, fitted with a pointer for precision readingsIn spite of the advantage of low-flow accuracy, the WARF/WARC features head losses smaller thanthose usually encountered in this type of meterHydraulic features in line with EEC standards following provision n° 75/33
