Its primary application is the accurate determination of the volume of water passing through a plankton net, although its robust design also makes it ideal for stationary monitoring in rivers and outfalls. By utilizing a three-blade impeller directly coupled to a non-resetting five-digit counter, the device provides a reliable mechanical record of every revolution during deployment.\n\u003c\/p\u003e\n\n\u003cp style=\"text-align: justify;\"\u003e\nEngineered for vertical operations, the \"back-run stop\" feature is critical for maintaining sample integrity, as it prevents the counter from registering reverse movements that could skew results. Constructed from a high-performance combination of plastic and titanium, the flow meter offers exceptional durability and corrosion resistance in aquatic environments. With a constant hydraulic pitch of 0.3 meters per revolution, researchers can easily convert mechanical counts into precise towing distances and volumetric data, ensuring that every expedition yields high-quality scientific evidence.\n\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIntegrated Back-Run Stop:\u003c\/strong\u003e Specifically designed for vertical deployments to ensure the counter only records forward flow.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePrecision Engineering:\u003c\/strong\u003e Features a three-blade impeller coupled to a five-digit mechanical counter.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRobust Materials:\u003c\/strong\u003e Built with titanium and technical plastics for maximum resistance in saline and freshwater environments.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVersatile Deployment:\u003c\/strong\u003e Suitable for both towed equipment like plankton nets and stationary flow monitoring.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHigh Accuracy:\u003c\/strong\u003e Delivers measurements within ± 5% in the primary range of 0.6 to 10 m\/s.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEasy Installation:\u003c\/strong\u003e Features a triple-point nose piece connection for secure mounting inside net rings.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSimplified Calculations:\u003c\/strong\u003e Standardized 0.3 m hydraulic pitch allows for rapid determination of filtered water volume.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cul class=\"tabs\"\u003e\n    \u003cli\u003e\u003ca href=\"#tab1\" class=\"active\"\u003eSpecifications\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003ca href=\"#tab2\"\u003eIn the Box\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003ca href=\"#tab5\"\u003eDocuments\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cul class=\"tabs-content\" style=\"text-align: justify;\"\u003e\n    \u003cli id=\"tab1\" class=\"active\"\u003e\n        \u003ctable style=\"width: 80%;
