Flowtech Z-5650 PSU Inline Rotameter – 20-200 L/min, 63 mm Solvent-Weld Socket

The Flowtech Z-5650 PSU inline rotameter provides direct visual measurement of clean-water flow from 20-200 L/min. Its polysulphone metering tube and union-ended construction provide a durable, power-free flow indication solution for water-treatment and process systems.Key features Direct visual flow indication without electrical power Polysulphone metering tube for robust water-system service Polypropylene float with an SS316 stainless-steel guide rod Viton O-rings for dependable union sealing Removable union-ended construction for inspection and maintenance Technical specifications Model: Z-5650 Water flow range: 20-200 L/min (5-50 GPM) Connection: 63 mm solvent-weld socket union Tube material: PSU (polysulphone) Float material: Polypropylene Guide rod: SS316 stainless steel O-rings: Viton Accuracy: ±5% of full scale Maximum working pressure: 10 bar Maximum working temperature: 60 °C Installation: Vertical, with upward flow Approximate dimensions: 290 mm body length, 375 mm overall socket length and 120 mm body diameter Typical applications Water-treatment and filtration systems Irrigation and water-distribution monitoring Process-water measurement Equipment commissioning and flow balancing Installation guidance Install vertically with the inlet below the outlet. Use compatible pipe, primer and solvent cement for the 63 mm socket connections. Support adjoining pipework so that no mechanical load is transferred to the meter body. Open valves gradually to avoid pressure shock and sudden float impact. Confirm material and seal compatibility before use with liquids other than clean water. Selection guidanceThis meter is calibrated for water. Select a range that places normal operation within the middle section of the scale. Fluid density and viscosity can affect readings with other liquids.
