What is a Coolant and Define Flow Meter

A coolant is a fluid used to carry away the heat from a system. Any liquid that can absorb or remove heat without changing its state chemically, such as water or oil, can be used as a coolant. A flow meter is an indicator) measures the volume of fluid that passes through it in a unit of time. This flowmeter helps to circulate coolant throughout the engine and removes the heat from inside, reducing the temperature. Here are all you need to know about the Coolant flow meter. Read on more about the Coolant flow meter.

The Working Principle of the Cooling System

According to the operating principle, it can be divided into closed and open types. A closed-type cooling system is mainly used for internal combustion engines, and it includes a thermostat, water pump, and radiator. The open-type cooling system has a more relaxed one end connected to the engine's cylinder head and the other end connected to an air duct that collects outside air for heat dissipation; thus, it dissipates heat generated from the internal combustion engine.

The Role of Coolant Flow Meter in the Cooling System

In general, the Coolant flow meter is mainly used for closed-type radiators, which are located in front of the vehicle and in charge of carrying away heat generated by the engine to the outside air. The Coolant Flow Meter's working principle is as follows: when the engine runs, the Coolant flow meter sends coolant from the Cooling Radiator through the water pump to the engine block. Then it absorbs heat generated by the engine and carries it to the air-cooled oil cooler. After flowing out from the Oil Cooler, the coolant is sent back to the cooling radiator via Water Pump and Coolant Flow Meter. In this way, to maintain a higher temperature of the coolant, a Cooling Radiator is needed.

The Common Types of Coolant Flowmeters

A type: Direct Flow Meter (also known as "direct reading"): It can directly read out the quantity and temperature of coolant easily by observing its movement; it's commonly used for measuring the Cooling flow meter.

Conclusion

Direct Flow Meter (also known as "direct reading"): It can directly read out the quantity and temperature of coolant easily by observing its movement; it's commonly used for measuring purposes. The structure consists of a transparent or translucent glass bottle, float, rod-shaped sensor probe with a flat tip, and a fine tube (orifice) in which float is installed. The liquid level of the coolant can be seen through the cooling flow meter.
