Tuning Fork Level Switch: 10 Frequently Asked Questions & Troubleshooting Guide

1. Can it be used for low-level alarm?

Answer:

Yes. When installed at the minimum permitted level, it can provide a low-level alarm or initiate pump protection.

2. Can a tuning fork switch protect a pump from dry running?

Answer:

Yes. A low-level tuning fork switch can detect insufficient liquid and send a switching signal to the pump control system.

3. Can a tuning fork level switch be used in a pipeline?

Answer:

Yes. It can be installed in a suitable section of a pipeline to detect whether liquid is present.

4. Can it detect an empty pipe?

Answer:

Yes. When the fork becomes uncovered, the output can indicate that the pipe is empty or that liquid flow has been interrupted.

5. Can turbulence affect a tuning fork switch?

Answer:

Strong turbulence can affect installation performance. The sensor should preferably be installed in a location with appropriate flow conditions and sufficient mechanical clearance.

Installation

6. How should a tuning fork level switch be installed?

Answer:

The sensor should be installed so that the fork can freely contact the process medium without touching the tank wall, internal structures or other components.

7. Can it be installed vertically?

Answer:

Yes. Vertical top-mounted installation is one of the most common configurations for tank level detection.

8. Can it be installed horizontally?

Answer:

Yes. Side-mounted installation is also commonly used for high- or low-level point detection.

9. Can it be installed from the top of a tank?

Answer:

Yes. Top-mounted installation is particularly suitable for applications where access from the side is limited.

10. Can it be installed from the side of a tank?

Answer:

Yes. Side mounting is often used when a specific high or low switching point is required.
