Many industries utilize various industrial technologies and equipment to ensure that the final product has the desired quality and quantity. Some of the instruments used in flow measurement include flow meters, flow-switches, and flow regulators or controllers. Although many people often mistake flow meters for flow switches, it is important to know their differences to benefit from these essential tools. This post will discuss a particular flow switch known as the paddle type. This will help you to make a clear distinction between a flow switch and a flow meter.
As you construct your flow system or application, I am sure that the thought of purchasing a flow measuring tool will cross your mind. Rushing to any vendor or manufacturer to buy a flow switch is not advisable. You need to buy your equipment from reliable companies such as Proteus. This will ensure that you get high-quality and durable flow measurement devices that will give you sufficient returns on investment.
What is a Paddle Type Flow Switch?
A paddle-type flow switch offers a cost-effective alternative to other expensive flow switches used in flow measurement industries. A paddle-type flow switch is designed using state-of-the-art technology that allows it to monitor fluids in the pipeline of a flow system. They are used to make the production environment safe by detecting leaks in flow systems that may lead to disasters. This is especially useful in industries that process, use, or transport highly flammable fluids.
The Working Principle of Paddle Type Water Flow Switch
In this type of flow switch, there is a paddle that connects to the level of the suspended liquid. When the liquid starts flowing using a paddle, it will trigger the contact in the microswitch by deflecting. A flexible metallic bellow is used to separate the microswitch from the liquid. Adjusting the setpoint is easily possible in a paddle-type flow switch. The force of the flowing fluid propels the paddle. This helps to detect incoming fluid flow within the flow system or pipeline.
If the liquid becomes static or if there is no flow, a spring will stretch and press the magnet vertically downward. When there is flow in the pipeline, the paddle will thrust upwards, rising at an angle of 20L~30L or beyond. This will cause the paddle’s eccentricity to push up the magnet. This reaction will actuate the reed switch that is connected to the circuit. The diameter of the pipe allows you to adjust the length of the paddle.
How to Install a Paddle Type Flow Switch
The approximate angle of the paddle determines the flow switch unit. The paddle’s lowest point determines the length when it angles the reed switch’s diameter and the pipe’s diameter. Based on your preference, you can choose to isolate the paddle at a suitable size of the pipe or an ideal pipe size mark. However, it should not be less than the 1-inch left.
The cutting face of the pipe and the paddle should be parallel, and the mounting screw needs to be 1-inch NPT.
The flow mark must be parallel to the ground and the pipe on the screw hexagon.
Ensure that the tape is implemented, and remember to tighten up the screw before installing the paddle-type flow switch.
Conclusion
Flow switches are essential instruments in a flow system because they can detect flow and monitor any anomalies. This keeps the working environment safe and helps prevent breakage and equipment damage. The paddle-type flow switch is quite affordable, and you can use it as an alternative to other expensive flow switch types. Remember to purchase flow switches from reputable companies to fully benefit from this essential flow measurement gadget.
