Many industrial works involve friction. Thus, it would help if you had coolant control to extend the life of your tools.

Coolant flow meter have a great role in the industries. By knowing their benefits, you can learn how to apply them. Keep reading to get informed about the major role of a cooling flow meter.

Role of Coolants

There are some roles that a coolant control should play in the machining process. First, they reduce and remove heat from the machine cutting zone. Thus, it ensures that the machine work is smooth and efficient. Reducing and removing heat reduces the effects of friction. It also ensures that the cutting tools have a long life. Heat weakens the cutting tool making it exposed to damage.

The coolant flow meter works as a lubricant to a machine. Thus, it reduces friction between parts. It, hence, makes the removal of chips from the tool easier. The tool also blows away chips and dust from the working surface. This makes the machining process smoother. The coolant control also protects the system from corrosion.

How Machine Coolant System Works

Machine coolant control is possible when the machine is running. Thus, the coolant fluid spreads over the working area. The flooding washes away dirt and chips from the working area. There is a sump at the bottom of the machine; It's where the coolant fluid collects. It goes through filtration and returns to the machine. The coolant circulation helps to control the heat created in the working area.

Coolants exist as single or central machine coolant systems. Thus, they all need tracking, nurture, and adjusting. But small coolant systems have a less effective filtration system.

Types of Coolants

There are four main types of coolants. They differ in the kind of machine they work with. Below is a brief of the four coolants.

Soluble Oils

This is the most common coolant control type. It is a water-soluble cutting fluid tool; You can use it for nearly all uses. But there are some drawbacks attached to this type of machine. First, it is prone to fungi and bacteria attacks. They manifest as morbid growths. It would help if you had high maintenance to avoid attacks.

Straight oils

This works with fluids that do not mix with water. In most cases, they have a form of minerals. They are petroleum products or contain lubricant matter like vegetable oil, esters, and fats. These are the best coolants you can use for lubrication—But their cooling ability is better than all other coolants in the market.

Synthetic Fluids

These are the best type of fluid for a coolant. They are made for one purpose. Thus, they contain no impurities like reject tramp oils or mineral oils. The downside is that they have the least lubrication. Therefore, you can only apply them in systems where lubrication is not vital. Alternatively, you can find other lubrication methods.

Semi-synthetic fluids

These are the best fluids you can get for coolant flowmeters. They offer both cooling effects and lubrication. As a result, they are less stinky than all other fluids. They also have less oil than their emulsion-based counterparts. As a result, you can apply them to a wide range of machining tools.

Coolant Concentration

You need to maintain appropriate coolant concentration levels. If the coolant levels drop, some issues may arise.

The problems that arise due to low concentration include corrosion of the machine, bacterial and fungal growth, and reduced machine life. You need to prevent the issues from saving your investment.

High concentration levels also come with their fair share of problems. It can lead to reduced heat transfer, reduces lubrication, foaming, wasted concentration, toxicity to the user, staining of the machine and its parts. It can also form a residue that reduces the machine's life.


Coolant flow meters are essential parts of the machining process. You can apply them in large-scale and small-scale firms. The proper coolant control and concentration will save your investment.
