Plastic & Acrylic Flow Meter (Rotameter) | Stark Water
Plastic acrylic flow meter (rotameter) by STARK provides clear, accurate indication of water and air flow for RO skids, dosing lines, and HVAC loops.
Product Description
Standard bodies are PVC or PP with a clear acrylic tube for excellent readability and impact resistance. Units include stainless-steel or optional plastic floats (range-dependent), O-ring seals, and union end connections for quick installation and service. Calibration can be supplied in L/h, L/min, m³/h or GPM to suit project specifications.
- Clean scale printing with protective window; optional dual-scale (water/air)
- Compact form factor for panel or in-line mounting
- Good chemical compatibility for typical water-treatment fluids
- Each unit tested for leakage and scale accuracy before shipment
Product Parameter
| Measurement Principle | Variable area (rotameter) with float in tapered acrylic tube |
|---|---|
| Media | Water or air (other compatible liquids/gases on request) |
| Body / Tube | PVC or PP body; clear acrylic tube |
| Float | Stainless steel / PTFE / PVC (per flow range) |
| Seals | EPDM standard; FKM (Viton) optional |
| Nominal Sizes | DN15–DN50 (1/2″–2″) typical; others on request |
| Connections | Union/threaded or solvent-weld; BSP/NPT available |
| Flow Ranges (water @20 °C) | Approx. 10–100 L/h up to 1–10 m³/h (model-dependent) |
| Accuracy | ±4% of full scale (typical rotameter accuracy) |
| Max Pressure | 0.6–1.0 MPa depending on size and material |
| Max Temperature | 0–60 °C (consult STARK for higher or chemical service) |
| Mounting | Vertical installation, flow from bottom to top |
| Compliance | Manufactured under STARK QA; pressure/leak tested |
Note: Final BOM (tube length, float material, scale units, and end connections) will be confirmed after your process data sheet is reviewed.
