Safety Instructions 1 Safety Instructions 1.1 Intended use The FVA Trogflux short version variable area meters are used to measure the volume of transparent liquids and gases passing through closed piping. The variable area meters can also be used for flow monitoring if they are equipped with one or more switching contacts. Standard scales are available for liquids with a density of 1 kg/l (62.43 lb/cu.ft). The scales must be recalculated for all other media depending on the physical characteristics. The devices are particularly suitable fort he measurement of: • clear liquids gas flows...

Safety Instructions The manufacturer certifies for the device FVA Trogflux short version meets all statutory requirements of the following EC directives by applying the CE marking: • Pressure equipment directive 97/23/EC The most hazardous permissable media are − for gases: fluids of group 2 for liquids: fluids of group 1. 1.3 Safety instructions from the manufacturer Disclaimer The manufacturer will not be liable for any damage resulting from the use of its product, including, but not limited to direct, indirect, incidental, punitive and consequential damages. Any product purchased from...

Standard device When starting up the unit, the following points must be observed: ● Make sure that the actual operating conditions (pressure and temperature) do not exceed the limits specified on the nameplate. Avoid float float impact! Therefore it is recommended to start with a closed shut-off valve during commissioning and adjust the operating pressure by opening the valve slowly. In particular, the use of magnetic valves is not recommended in this case. When measuring liquids, make a careful release of the pipeline to prevent water hammer by gas bubbles. When commissioning new devices...
