Why Liquid Level Gage Fail?

When a liquid level gage is broken, it provides inaccurate output and leads to bad decisions. And bad decisions often lead to process downtime or, worse, accidents. The frustrating part is that the damage of these expensive devices that causes potentially dangerous issues could be easily prevented if one knows how to handle them properly.

Here are some of the common reasons for gage failure and recommended solutions to help avoid the headaches of frequent replacement and risks of inaccurate readings.

1.       Temperature – Extremely high or low temperature can damage a liquid level gage and other similar devices. Gages not designed for extreme operating conditions can malfunction in a relatively short period of time.

2.       Overpressure – Gages function well in the right amount of pressure during process monitoring. However, when pumps are switched on or off, or valves are opened or closed, a surge of media flows through the pipe and impacts the pressure gage, causing a spike that can damage it seriously.

3.       Clogging – Clogging can be a serious problem for liquid level gages, especially with processes that result to crystallization or congealing. Gages that become clogged often freeze up and just stop functioning.

4.       Mechanical Vibration – Studies have shown that vibration is one of the primary causes of gage failure in manufacturing facilities. Vibration brings about two negative impacts on gage accuracy. First is the difficulty to accurately read a pointer and second is moving the pointer to zero, both producing inaccurate readings.


These are just some of the common causes of gage failure. Remember, a liquid level gage, when used inappropriately, can provide inaccurate readings and, worse, be damaged immediately. Ensure that you are using your gages and liquid level indicators under the right working conditions.
