It is installed on the return pipe, just before the electrolyzer cell or the pH regulator's analysis chamber, and detects the presence or absence of water circulation in the hydraulic circuit. As soon as the water flow becomes insufficient or stops—for example, when the filtration pump stops, a valve is closed, or a filter is clogged—the detector sends a signal to the control unit to \u003cstrong\u003eimmediately stop chlorine production or chemical injection\u003c\/strong\u003e. This safety feature protects equipment, preserves water quality, and complies with regulatory safety requirements for automated systems.\u003c\/p\u003e\n\n\u003ch2\u003eWhy is a flow switch mandatory on an electrolyzer or pH regulator?\u003c\/h2\u003e\n\n\u003cp\u003eA salt chlorinator produces chlorine by electrolyzing saltwater circulating through its cell. If the water stops flowing while production remains active, chlorine accumulates at an extreme concentration in the cell—which can cause rapid deterioration of the electrodes, or even rupture of the cell itself. Similarly, a pH regulator equipped with a dosing pump injects an acid or basic corrector into the pipe. If injection occurs without water circulation, the concentrated product stagnates in the piping or flows back into the analysis chamber, which can damage the probes and skew readings for several days.\u003c\/p\u003e\n\n\u003cp\u003eThe flow switch prevents these two scenarios by automatically shutting down the device as soon as circulation stops. It is a \u003cstrong\u003epassive safety device\u003c\/strong\u003e that operates without user intervention: as long as water circulates normally, the detector's electrical contact remains closed, allowing the device to operate. As soon as the flow drops below the minimum threshold (4 m³\/h for this model), the contact opens and cuts off power.\u003c\/p\u003e\n\n\u003ch2\u003eCCEI Compatibility: Limpido, Phileo, Oxeo, Phenix, and all regulators with 2-pin plug\u003c\/h2\u003e\n\n\u003cp\u003eThis Noryl flow switch is equipped with a \u003cstrong\u003e2-pin round plug\u003c\/strong\u003e, the standard connection format for CCEI devices. It is compatible with the entire range of CCEI automatic treatment systems, including:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLimpido Electrolyzers\u003c\/strong\u003e (Limpido XC LAB, Limpido Pro pH, Limpido Pro Lab, Limpido LTE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhileo pH Regulators\u003c\/strong\u003e (Phileo, Phileo LT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOxeo pH and ORP Regulators\u003c\/strong\u003e (Oxeo, Oxeo LT, Oxeo SP)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhenix Combined Regulators\u003c\/strong\u003e (pH + ORP + Redox analysis)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIt connects directly to the control unit via its 2-pin connector. No electronic configuration is necessary: the system automatically recognizes the presence of the flow switch and activates the safety function.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications: Noryl, 3\/4 thread, 7 cm paddle, 4 to 22 m³\/h flow rate\u003c\/h2\u003e\n\n\u003cp\u003eThe body of the detector is made of \u003cstrong\u003eNoryl\u003c\/strong\u003e, an engineered polymer resistant to pool chemicals (chlorine, acid, soda) and UV. This material ensures maximum longevity even in a chemically aggressive environment.\u003c\/p\u003e\n\n\u003cp\u003eConnection is made via a \u003cstrong\u003e3\/4 inch thread\u003c\/strong\u003e. Installation is done on the return pipe using a \u003cstrong\u003eØ 50 mm saddle clamp\u003c\/strong\u003e (not supplied) and a threaded adapter, which allow the detector to be mounted without cutting the pipe. The \u003cstrong\u003edetection paddle is 7 cm long\u003c\/strong\u003e — this is the moving element that pivots under the action of water flow and activates the electrical contact.\u003c\/p\u003e\n\n\u003cp\u003eThe detector operates within a \u003cstrong\u003eflow rate range of 4 to 22 m³\/h\u003c\/strong\u003e. Below 4 m³\/h, the contact opens and stops the connected device. Above 22 m³\/h, the detector remains in the active position but should not be used under these conditions for prolonged periods, as excessive flow can prematurely wear the paddle. These values correspond to standard flow rates for residential filtration pumps, which typically run between 8 and 18 m³\/h.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation: on Ø 50 mm pipe, upstream of the cell or analysis chamber\u003c\/h2\u003e\n\n\u003cp\u003eThe flow switch is mounted \u003cstrong\u003ejust before the electrolyzer cell or the pH regulator's analysis chamber\u003c\/strong\u003e, on the return pipe, after the filter. It must be positioned so that the paddle is free to pivot under the action of the flow — avoid placing it in an elbow or too close to a fitting, and respect the \u003cstrong\u003edirection of water flow\u003c\/strong\u003e indicated by the arrow molded on the detector body.\u003c\/p\u003e\n\n\u003cp\u003eInstallation via a saddle clamp allows for installation without cutting the pipe and without draining the circuit. The clamp is fixed around the Ø 50 mm pipe, then the pipe is drilled through the clamp, and the adapter and then the detector are screwed in. The 2-pin electrical cable is then connected directly to the dedicated socket on the electrolyzer or regulator housing.\u003c\/p\u003e\n\n\u003ch2\u003eWhen is a flow switch absolutely required?\u003c\/h2\u003e\n\n\u003cp\u003eThe use of a flow switch is \u003cstrong\u003emandatory in the following cases\u003c\/strong\u003e:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eInstallation with a \u003cstrong\u003evariable speed filtration pump\u003c\/strong\u003e, because the flow rate can vary depending on the program and fall below the electrolyzer's operating threshold without the pump stopping completely.\u003c\/li\u003e\n  \u003cli\u003eInstallation with a \u003cstrong\u003etechnical room located above the pool level\u003c\/strong\u003e, because if the pump stops, water can flow back and cause the circuit to lose prime, leaving the cell or probes dry.\u003c\/li\u003e\n  \u003cli\u003eInstallation with \u003cstrong\u003emulti-way valves or bypasses\u003c\/strong\u003e, which can accidentally cut off or reduce flow to the electrolyzer or regulator without stopping the main pump.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eEven when these situations do not apply, installing a flow switch remains excellent preventive safety practice that protects your equipment investment and prevents costly breakdowns.\u003c\/p\u003e\n\n\u003ch2\u003eDiagnosis and replacement: how to test a faulty flow switch\u003c\/h2\u003e\n\n\u003cp\u003eIf your electrolyzer or regulator displays a flow error or does not start despite the pump running, the flow switch may be the cause. To test its proper functioning, unplug the connector from the housing, set a multimeter to the \"Ohms\" function, then test for continuity between the two pins of the connector with filtration running. If the device indicates \u003cstrong\u003e0 ohm\u003c\/strong\u003e, the detector is working normally. If no value is displayed, the internal contact is faulty and the detector must be replaced.\u003c\/p\u003e\n\n\u003cp\u003eCommon causes of failure include mechanical wear of the paddle (which can get stuck or break after several years), fouling of the mechanism by limescale deposits or algae, or oxidation of electrical contacts in a humid environment. Replacing the flow switch is a simple operation that does not require draining the circuit.\u003c\/p\u003e","brand":"CCEI","offers":[{"title":"Default Title","offer_id":52139610669393,"sku":"SF160006","price":96.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0965\/5880\/9425\/files\/4956-12533-3-SF160006__89492__33694.1741076969.1280.1280.png?v=1760806429","url":"https:\/\/www.poolplanet.com\/en\/products\/detecteur-de-debit-avec-prise-ronde-deux-point","provider":"Pool Planet","version":"1.0","type":"link"}
