Purpose and functions of Plastic Level Switches in industrial processes


If you have an experience  working as a operator you can better understand when an operator is searching for a plastic level switch, they are usually looking to control or maintain a certain liquid level within a chemical holding tank, because these plastic level switch not only controls the level but provide standard accuracy. Basically the purpose of a liquid level switch is to activate pumps, valves, or alarms at specific set points that the operator is able to adjust to their own specification.


The PLF series plastic level switch is a fantastic option for chemical level control, and offers the client a completely corrosion resistant plastic level switch. The PLF series plastic level switch is available in PVC, PP, PVDF and 316SS to cater to any chemical application that requires a plastic level switch. The PLF series plastic level switch can be customized to incorporate eight different level switch points, and with a metal support rod the PLF series plastic level switch is the most rugged plastic level switch on the market today.

 The PLF series plastic level switch comes standard with a plastic junction box and installation fitting and will thread directly into a 2” bulkhead fitting or side mount bracket. The PLF series plastic level switch can be wired normally open or normally closed to cater to the specific application that the client is looking to install into. When a local automotive manufacturing company was looking to maintain the liquid level in a lubricant tank using a plastic level switch, they chose the PLF series plastic level switch.

The  automotive manufacturing company simply installed the PLF series plastic level switch into the bulkhead fitting on the lubricant tank and chose to incorporate three different floats to start a pump, stop a pump, and sound a low-level alarm when it was time to order more lubricant for their process. The PLF series plastic level switch has enabled them to automate the process and no longer monitor the lubricant tank to ensure that they have product left when they require it. It is all monitored remotely by the PLF series plastic level switch.

When chemical distributors drive out to a customer site to fill a tank it is important that they do not overfill the tank and the PLF series plastic level switch will monitor the level and alert them when they are in a high level, overfill condition. This application where the PLF series plastic level switches generates an alert to maintain the level of liquid is perfect for many industrial processes. So, industries don’t have to worry about wastage of expensive chemical liquids when they are using plastic level switches.

Top Reasons Why You Should Select a Paddle Wheel Flow Meter

Image
The primary role of a flow meter is to manage the flow of liquid substances. The flow meter measures the flow of water or fluids to tell you how many liters you have already used, or how much flow do you have currently. Similarly, paddle wheel flow meters can measure accurately the volumes of water or other flowing fluid. In short, they are used for monitoring the liquid flow rates. These paddle wheel flow meters are also known as inline flow meters or insertion flow meter. Paddle Wheel Flow Meter Paddle wheel flow meter response fast, it works well with the clean fluids. A flow meter has three components: Pipe fitting, Paddle wheel sensor, and flow display. The pipe fitting can be used in different applications. The Paddle wheel sensor is an electronic sensor where magnets are embedded with the paddle wheel. While the fluid flows through the pipes it causes spinning of the paddle wheel. The magnets help the electrical pulse to calculate the ratio of the spinning. The ‘Flow D...

4 Common Types of Liquid Level Sensors and Their Uses

Image
We know that liquid level sensors are used for monitoring free-flowing substances to regulate the process in a particular way. Usually, these substances are liquid. However, some solids like powdered substances can be measured by the liquid level sensor. Most of the liquid level sensors are used industrially. These have been in markets for decades. Food and beverage, agriculture, printing, medical and domestic, and automotive industries use these type of sensors for level measurement or leak detection. For instance, liquid level sensors are used in cars to monitor liquids including oil, fuel or power steering fluid.  You can also found them in household machines such as a coffee machine. A level sensor is used to identify a liquid rise and fall point, total amount of liquid in a container, and continuous measurement of volume. The primary purpose of using a level sensor is to monitor and regulate the liquid level within a contained space such as huge tanks and vessels. ....

Why Leak Detection Switch Is So Important For Double Walled Tanks

Image
When it comes to chemical processing companies, for most aggressive chemical tank applications, clients will look to get a dual-contained tank. A dual contained tank is essentially a tank within a tank and it prevents a leak that may cause an injury or fines. A leakdetection switch is a mean to ensure that if there is a crack in the primary tank the operator will be made aware of the leak prior to it filling up and overflowing into the environment. One of market’s finest switches is LD series leak detection switch. The LD series leak detection switch for chemicals or water was manufactured to eliminate the overfilling of the secondary containment but to also ensure that the operators are informed on when a leak occurs. A leading tank manufacturer that specializes in double walled tanks has now standardized on the LD series leak detection switch for all chemicals. The LD series signal can be connected directly to a ProAlert Audible/Visual alarm which will most certainly get som...
