Section 3 Installation

Note

Do not attempt to run a sampler from a power source installed on a flow meter. While a flow meter will operate satisfactorily powered from a sampler, the reverse is not true. The sampler's pump draws heavy current, particularly on startup. The flow meter-to-sampler connect cable cannot carry such currents. If you are using a single power source for a flow meter-sampler combination, always install the power supply on the sampler.
