Acrylic Body Rotameter

1. Product Description

Locus Acrylic Body Rotameter is a variable area flowmeter that provides a direct visual indication of fluid flow. It features an acrylic body with a precisely machined tapered bore and a float that rises and falls based on flow rate. This flowmeter is designed for industrial applications requiring clear, durable, and accurate flow measurement.

2. Specifications

• Body Material: Clear Acrylic
• Float Material: SS 316 / PVC / PTFE
• End Connections: Threaded / Flanged
• Flow Range: 10 LPH to 5000 LPH (Water) / 1 to 100 NM³/hr (Air)
• Scale: Engraved / Printed Scale
• Gaskets: Neoprene / PTFE / Viton
• Ingress Protection: IP65 (Optional)

3. Working Principle

The rotameter operates on the principle of variable area flow measurement. The fluid enters the bottom of the tapered tube and lifts the float to a position where the upward force of the fluid matches the downward gravitational force. The height of the float in the tube directly corresponds to the flow rate.

4. Assembly

1. Body: Transparent acrylic block with a tapered bore.
2. Float: SS 316 or equivalent material based on application.
3. End Connections: Threaded or flanged for easy installation.
4. Scale Markings: Engraved or printed for clear visibility.
5. Gaskets & Seals: Ensures leak-proof performance.

5. Installation Process

1. Positioning: Install vertically with flow from bottom to top.
2. Mounting: Secure it to a panel or inline with appropriate fittings.
3. Connection: Use PTFE tape to prevent leakage in threaded models.
4. Calibration: Verify readings against a standard flow rate.
5. Startup: Gradually introduce fluid flow to avoid float damage.
