5 Things You Must Know About Flow Meters

Flow meters are important and indispensable devices in any water treatment system. They have the role of monitoring and ensuring that the system is operated according to the original design capacity requirements. In addition, flow meters also help operators control the amount of water lost, the amount of finished water, the amount of waste water and the total amount of water instantaneously per unit of time.

What do you know about flow meters?

Flowmeters are usually connected directly to pipes, used to measure the amount of water moving over a certain period of time.

Currently, there are many types of flow meters with different shapes and sizes, capable of measuring flows from a few dozen liters to a few hundred cubic meters of liquid or gas within 1 hour, 1 minute or 1 second. However, the choice of device size and measurement threshold depends on the purpose of use and the available pipe size. The larger the size of the device, the more water can flow with greater capacity and speed.

How it works?

Flowmeters are made up of several parts such as floats, measuring tubes and scale markings. They operate on the following principles:

• The device will operate without the presence of any external energy source such as electricity, gas, light… The device will automatically measure most accurately when there is flow through the pipe. However, it is still affected by some factors such as changes in temperature, pressure, viscosity and density of liquid…
• When operating, the flow meter will be placed vertically in the direction of the liquid flow from bottom to top. The float of the flow meter has a diameter nearly equal to the diameter of the air intake pipe of the flow, the float is made of many different materials such as stainless steel 304, stainless steel 316, plastic,  The float will be lifted from the bottom position, passing between the float and the pipe wall when the liquid enters the pipe. When it floats up, the liquid will flow through and will stop at the point where the flow is large enough for the entire amount of liquid to flow through. The flow reading position is the top surface of the ball intersecting the scale on the wall of the flow meter tube
• The measuring lines are imprinted on the product surface along with the delicately crafted measuring float to ensure stable measurement and easy viewing of the scale.

The most popular types of flow meters today 

There are many different types of flow meters on the market today. However, they can be divided into three types based on their shape.

Round shape 

Circular flowmeter connects directly to the pipe to determine the flow rate at a given location.

• Product Name: Round Flowmeter LZM-75GF 1100 L/P
• Origin: China
• Flow rate: 450-1100 L/min
• Application: Apply to RO panel or pipe, D90mm connection pipe, female thread/pipe glue/flange.

Square shape

Square flowmeter is used to measure and compare phase difference of flows, installed directly on the surface of electrical cabinets, flat stainless steel control surfaces…

• Product Name: Square Flowmeter LZM – 40 300 L/P
• Origin: China
• Flow rate: 40-300 L/min
• Application: Apply to RO control panel, connection pipe D49mm, male thread.

Square type is commonly used in commercial, domestic or small capacity systems. In addition, round type equipment is more versatile, used in applications requiring large capacity or can be used for domestic and commercial systems.

Applications of flow meters that you should know

Flowmeters are used in many different fields such as:

• Measure water/liquid/gas usage instantly.
• Water flow measurement is used in industrial wastewater treatment systems, pure water filtration lines, ultra-pure water, water for boiler systems, etc.
• Measure the amount of water flowing into and out of tanks to avoid overflow or poor operation of wastewater treatment system equipment.
• The device can also be used to measure the flow of chemicals, sludge, high density gas, milk, etc. in other industries.
• Help users control the system to work effectively; avoid incidents that arise, causing major damage and cost losses.
• In RO water treatment systems, the device is installed for each membrane shell. This helps to measure the water flow to each membrane cluster to monitor the difference, so that when encountering abnormal factors, users will quickly detect and handle, or determine which membrane cluster has low efficiency and needs to be replaced first.
