When to Use a Custom Fluid Switch Instead of a Standard Fluid Switch

0

Those who work in industries related to the engineering and manufacturing of certain fluid or liquids will be familiar with devices called float switches. These switches are designed to help monitor liquid levels under certain circumstances. A switch will trip when the liquid or gas being measured reaches a certain level, giving an output or reading that can be recorded, or it will trigger a certain other mechanical response.

While there are standard devices that will serve these purposes, more often than not it will become necessary to have a custom fluid switch designed and developed for a project. Here are a few things that might indicate that you should go with a custom fluid switch instead of a standard one.

Environmental Factors

When you are looking through different types of float switches to find the right device for your project, some of the first things you will need to consider are the environmental factors surrounding your project and the liquid you are monitoring.

A few things that will contribute to the type of device you eventually go with include the pressure of the environment in which you are monitoring your liquid a well as the temperature at which the liquid will be at while the float switch is in use. The depth of the liquid that is being monitored will also need to be taken into account as some types of float switches will not work well at great depths.

Another thing to consider is whether or not the liquid or gas you are going to be using your float switch with is hazardous or explosive. There are explosion proof switches that can be used in such environments, but not all are made with this intent. For this reason, it is important that you find a float switch manufacturer who can provide you with a custom device that will be safely operational under such circumstances.

Location and Arrangement

The next thing that you will need to bear in mind is the manner and placement of the device. For instance, will the float switch be mounted onto the vessel containing the liquid being monitored in a vertical or horizontal orientation?

There are float switches that are designed for both orientations, but if the mounting position that will be required to accurately monitor the liquid or gas that you will be working with doesn’t exactly fall within the direct parameters of a standard orientation, then you should have one custom made to suit your needs.

Another thing to consider is whether your switch needs to be contained within its own fixed housing inside the vessel or tank containing the liquid or not. Some projects require that the float switch is installed at the bottom of the tank while others need it at the top.

Furthermore, some materials can cause a build-up of residue on a switch which could inhibit the ability of the device to produce an accurate reading. If this is the case for your project, then you will need a custom designed product.
