Description
The FR-50 single sensor flow reservoir provides sample calming for dissipation of air-bubbles and settling of suspended solids, foam or other impurities commonly observed in drinking water influent. This unique flow reservoir design results in the highest level of oxidizer resolution on the market and greatly extends the maintenance cycle of the sensor while providing a large buffer capacity to mitigate pressure fluctuations.
The minimum inlet pressure of FR-50 flow reservoir is only 7.5 psi (0.0Smpa) making it highly suitable for the end of pipe networks and secondary supply influent sampling. One FR-50 is provided with the purchase of each ST-765SS Series sensor and comes equipped with inlet PRV, Rotameter and Digital Hall Effect flow meter for the recommended flow range of 600-1800 ml/minute. The FR-50 outlet flow and sewer overflow lines should be diverted to drain or the inlet of the pretreatment system for those desiring NSF compliance.
