An in-line water flow meter is a good device that will offer you a high degree of water monitoring accuracy. Every day, water demand is rising. That is due to an increase in population. But clean water is not that plenty. So, it's vital to ensure the little available is used well, and with an in-line water flow meter, you will understand the water usage without hassle.

Sometimes, the water flow rate may go low or high. But how low can the in-line water flow meter help you to gauge low water flow velocity? It is vital to track small water quantity. That way, you can identify any leaks from your water system. Just get an in-line water flow meter, and it will help you measure a low flow rate and get accurate results.

The lowest in-line flow meter can go

Every in-line flow meter has a turndown ratio. A classic adjustment range is a 10:1 ratio. That will offer you the best accuracy over the whole range. But don't forget that a sensor will not be damaged through over ranging.

How low liquid in-line flow meter works

There are several in-line low flow meters. They function in different ways. But they will all help you to monitor the flow rate of the liquid you want to monitor. You can be sure to get an accurate low flow rate when using any of them. 

• Ultrasonic low liquid flow meter

This device works based on the ultrasound that travels within a fluid flowing inside a small pipe over a long distance. The high signal in relation to noise ratio from ultrasound in-line flow meter has proven reliable when measuring low liquid flows with great precision.

• Coriolis low flow meter

You can use this in-line flow meter to detect a very low flow rate of the fluid being monitored. This meter doesn't require movement of fluid to react with energy input within the flow system.

• Variable area flowmeter

While you can use this flow meter to gauge your fluid's low flow rate, it's not the most effective. It can easily be affected by the properties of the liquid. It can adjust the height attained by the float and also the flow rate indication. It doesn't offer you an electronic output.

• Low flow axial turbine flowmeter

It's an in-line water flow meter you can use to measure a low flow rate. But doesn't function very well in low flow. The energy needed to spin the rotor can be swamped by any drag from the system when there is a low flow rate. A change in viscosity or fluid density may also affect calibration. This device can give you the best results if you measure turbulent flow, which is very rare in low flow. You can get a small polymer axial turbine device that can guarantee you an accurate low flow rate. But the biggest change is that any change in properties of the fluid can be a big issue.

Conclusion

A low flow liquid in-line flow meter can help gauge how low the rate of fluid flow is. But not all of them will give you the most accurate results. Ensure you choose an in-line flow meter that is compatible with the fluid you intend to monitor. Once you have installed it, it is crucial to maintain a close check.
