We hear a lot about measuring liquids and the need to measure liquids in factories. The demand is being raised due to many concerns where safety and cutting costs is one of the core issues. A liquid level indicator is being used in more than just a single industry now. Its use has been accepted by almost all the huge industries and there are many different types of these liquid level monitoring devices and gadgets being used in the different areas. There are many different types of monitoring gadgets available in the markets today. Some of the commonest are as listed below.

See through glass strip indicator
As almost clear by its name, this type of indicator is a glass strip from where the human eye can see through and monitor the level. Usually this indicator is attached to small containers which do not hold too many gallons of liquid. As the more liquid you pour into the container the more pressure it builds on the walls, the see through glass liquid indicator is used in small tanks and container mostly which contain samples.

Suspended buoy (float indicator)
For the tanks which hold high amount of liquids, possibly in hundreds or even more, the plastic buoy suspended through a chain is used as the indicator. As the buoy stays afloat the liquid, as the level rises and drops, so does the buoy which is attached to the gauge through a chain. The movement within the tank is visible on the gauge outside and the staff can read the liquid level on it.

Radar wave liquid monitoring gadget
This is one of the fastest battery operated liquid level reading gadget available today. A small electronic device remains at the top with an iron or an alloy stick protruding from it which is immersed in the liquid until the bottom. The device creates radar waves which travel at lightning speed all the way to the very end and bounce back as soon they touch the liquid’s surface. The distance and time a wave travels calculates the measurement of the liquid level.

Ultrasonic liquid level indicator
This is somewhat quite similar in functionality with the radar wave but it differs from all other because it has no part touching the liquid in any way. The ultrasonic level indicator is totally a non touch measuring device and it uses the ultrasonic waves which are completely harmless. Since it does not need to touch, nor does the waves cause harm, it is the safest to use and can be used with any kind of liquids.
