Types of Leak Detectors and How They Work

Types of leak Detectors

There are mainly three types of methods when it comes to detecting water leakage of an establishment.

  1. Flow Meters
  2. Acoustic Sensors
  3. Flood Detectors

1. Flow Meters

Water Flow Meters

Water flow meters are probably the most efficient way to prevent leakage in your building’s plumbing system. It increases the likelihood of acquiring all the benefits stated above.

These devices are strategically placed in your pipeline to keep the flow and pressure of water in check. Whenever there is a fluctuation outside the normal range, it will alert you before the emergency, saving you from greater property damage.

Modern-day flow meters are sometimes also equipped with AI and valve control. They are able to automatically shut down lines through which excess water is leaking out. Furthermore, some of them can even be connected to your Wi-Fi. On top of that, you can control and check all the points from your smartphone.

2. Acoustic or Ultrasonic Sensors

Ultrasonic leak Sensors

You guessed it right; these devices can detect water leakage via sound. You might have heard of strong hissing sounds coming from large leakages yourself. However, these sensors can pick up sound from the frequency range beyond the human capability or sometimes too hard for them to catch.

As long as the leak is turbulent -i.e., the flow of the leak is uneven and not continuous at an equal rate- the ultrasonic sensor will have the ability to detect the leakage. Even if the leak happens to be at a point where we cannot see or hear with our human organ, it will easily detect that.

Ultrasonic leak detectors are most sensitive to the frequency range around 40 kHz, which is twice the frequency of the maximum range of human hearing; this is why it is very well-suited to detect internal leakage in the system.

Moreover, since ultrasound is focused on a specific band of sound, it is important to leave out outside background noise and detect the exact source of the leak.

3. Flood Detectors

Flood Leak Detectors

These types of sensors are probably the most commonly used leak detectors in the market. Due to its low cost and ease of installation, it is sensible that it is at the top in popularity.

The devices can be set up easily in a matter of seconds. A flood sensor would trigger an alarm whenever it comes in contact with water on the floor.

Sometimes they also come with adjustable sensitivity to avoid false alarms in places with high humidity. Others may also have temperature sensors to alert the user in precautions before actual flooding.

Since these devices are available at a lower cost and are usually not set up directly in the pipeline, they have the drawback of not having any automatic valve control to stop the flow by itself.
