Maintenance-free Sampling System
The non-fouling FlowSampler draws representative samples in high-solids applications without pre-filtration.
The FlowSampler is a patented sampling device from LAR which does not require filtration because sample is siphoned-off fromsample stream towards the main flow direction of the water. Therefore, no large particles can get into the sample stream. The smaller particles are collected because the unaltered sample then enters the system. The FlowSampler can handle even difficult challenges like the sampling at the inlet of a sewage treatment plant or before the course screening.
The FlowSampler from LAR is installed next to the analytical device (i.e. at the wall).
In the installation photo below, two FlowSamplers are installed alongside two QuickTOC analyzers.
The FlowSampler sampling device requires a flow of 2-5 m³/h (max. 10 m³/h) and at a max. counter-pressure of <0.2 bar at the sampling tube of the FlowSampler (Di = 3). The temperature of the sample should be less than 50°C. For sample temperatures up to 90°C, a special PP version of the FlowSampler is available.
The connection of the FlowSampler can be realised as a PVC tube screwing of 32 mm (external) or as tube connection for a pressure hose with 30 mm internal diameter. For the sample drain the same dimension are valid.
The sample dosing can be done by an immersion pump which may require a cutting device, depending on sample composition. The pump should has to guarantee the necessary flow of 2-5 m³/h (max. 10 m³/h) over the bridged distance.
