3. Working

The Metal Tube Rotameter operates on the principle of variable area flow measurement. The fluid flows through a tapered metal tube, causing a float to rise. The float’s position is detected by a magnetic sensor, which transmits the reading to the indicator.

4. Principle

The float inside the tube moves up as flow increases.
A magnet inside the float couples with the external pointer, ensuring precise flow indication.
The float stabilizes at a point where the force of the flowing fluid balances gravity.
The movement of the float is translated into flow rate measurement.

5. Assembly

The Metal Tube Magnetic Rotameter consists of a stainless steel tube, floating element, magnetic coupling, and indicator mechanism.
The magnetically coupled pointer ensures precise and stable readings even in hazardous environments.

6. Installation Process

Ensure the vertical mounting of the rotameter.

1. Connect the inlet and outlet flanges as per the flow direction.
2. Secure all connections using the required gaskets and bolts.
3. Ensure there is no reverse flow in the pipeline.
4. Check for leaks and calibrate if necessary.

10. FAQ (Frequently Asked Questions)

Q1: Can Locus Metal Tube Magnetic Rotameter handle high-pressure applications?
✅ Yes, it is designed to operate up to 40 bar pressure. Higher pressure models are available on request.

Q2: What types of fluids can it measure?
✅ It is suitable for water, oil, chemicals, gases, and pharmaceuticals. For corrosive fluids, PTFE lining is recommended.

Q3: Is calibration required after installation?
✅ No, it comes pre-calibrated, but annual recalibration is recommended for accuracy.

Q4: What is the difference between Glass Tube Rotameter and Metal Tube Rotameter?
✅ Metal Tube Rotameter is used for high-pressure and opaque fluids, whereas Glass Tube Rotameter is suitable for low-pressure, transparent fluids.

Q5: Does it require electricity for operation?
✅ No, the basic model is mechanical and does not require electricity. However, digital models with transmitters are available.
