Why Measure Level?

This addresses the most frequently asked questions about level measurement, including “What is the correct level measurement technology to use?”, “Should I use a point switch or continuous measurement?”, “How do I install my level equipment?” and more.

1. Why measure level?

There are multiple reasons to measure level of liquid or solids products: for inventory monitoring, for safety, for re-ordering, and so on. It is a common-sense thing to do, and conforms to general health and safety guidance.


2. What is the correct level measurement technology to use?

This is where things get more complex. There is a vast array of level/contents monitoring equipment on the market, ranging from the most basic and simple to cutting-edge technology, and by and large they all have their place.

Some technologies are effectively obsolete but remain in use due to their low initial costs, but increasingly users are seeing the benefits of more modern equipment. A quality equipment supplier will be able to assess the particular requirements of your application and recommend the appropriate solution.


3. Should I use a point switch or continuous measurement?

Again, this will depend on your application and what information you require. If you only require a high- or low-level alarm, then a point switch, such as a vibrating or capacitance probe, is an effective solution. Applications where real-time level updates are required will need a continuous probe, such as a radar or TDR device.


4. How do I install my level equipment?

Obviously this will vary from device to device but some useful rules of thumb include: do not mount the device where it can be impacted by product inflow; avoid heaters or agitators; be aware of any internal tank geography that may interfere with the device’s signal, and try to choose equipment that compensates for this or is unaffected by it. A quality level equipment supplier will also be able to consult on installation issues and offer specific advice. Some may even offer to install and set up your system for you!
