Flow meters and water flow switches are essential tools for measuring flow rates in many industrial and domestic environments. Many different flow meters and flow switches are popping up every day, making selecting flow meters hard. If you are unsure which flow meter or flow switch will make an ideal choice for your application, continue reading this post for more insights.
Differences Between Flow Meters and Flow Switches
When you want to select flow meters or switches, knowing the basics of how these instruments operate will help you make the right choice. What differentiates these two devices is how they operate when measuring flow rate. A flow meter functions by monitoring the flow rate. The user needs to physically check the readings from the flow meter. On the other hand, a flow switch is an effective flow measurement device used to detect flow presence at a set point that is already predetermined once it does this or will alert the user or take a certain action.
What is a flow switch?
When you want to control the flow of liquid, steam, or gas, you need a switch that operates mechanically. This type of device is called a flow switch. Trip signals from water flow switches are usually sent to other devices such as the pump and other equipment within the flow system. A flow switch can send signals to the pump, instructing it to turn on or shut off. This is to prevent damage to other systems when there isn’t enough flow or no flow at all. It also helps to protect the cooling circuit. Water flow switches are used to determine flow rate according to preset parameters. The specifications of an instrument will either make it fixed or adjustable. The electric circuit actuation responds to the reached set point. Unless the flow rate falls below the set point, the switch will stay in its new state when it trips.
What is a flow meter?
A flow meter is a device that measures the flow rate of fluids and glasses, linearly or nonlinearly. The flow rate measurement can either be volumetric or mass. A flow meter can control output flow if fitted with an integrated flow control valve. A range of factors must be observed when buying and installing a flow meter. One of them is whether the plant personnel can operate such an instrument. Do they know how to carry out maintenance or perform calibration? Are the spare parts of the flow meter easily available? You also need to consider the instrument’s life span.
Flow meters are usually designed according to a particular application. You can use a flow meter in any industrial application that you come across. If you need to choose the right flow meter for your flow system, you need to know how it operates. A flow meter’s main features will help you distinguish which application it is best suited for. All flow meters come with a written set of rules of how you are supposed to install, read, and maintain them. It is therefore paramount for you to be acquainted with all specifications.
This will help you narrow down your search when trying to get the right flow meter for your application.
Benefits of flow meters and flow switches
Flow switches and flow meters are essential devices that should never lack in a flow system, no matter how large or small it is. One awesome benefit of both water flow switches and flow meters is that they come in various designs meant for different applications.
Getting an accurate flow rate without flow meters and water flow switches. If you are unsure which type of flow switch or flow meter is for your flow system application, ask the manufacturer to give you pointers on how to select proper flow meters and switches.
