Instantly Learn How to Read "Flow Rate"

We often hear about LPM, which stands for liters per minute. Below are some commonly used flow rate units and their applications:

1. Liter/Minute (L/min): Also known as LPM, frequently used to measure liquid flow rates, such as in water treatment equipment and the delivery rate of liquids in medical devices.
2. Liter/Hour (L/h): Used for measuring longer-term liquid flow, like in the chemical industry.
3. Cubic Meter/Minute (m³/min): Used for large-scale liquid or gas flow in industrial systems.
4. Cubic Meter/Hour (m³/h): Describes large flows over time, like in municipal water supply.
5. Cubic Foot/Minute (ft³/min): Measures gas flow in HVAC and industrial piping.
6. Cubic Foot/Hour (ft³/h): Long-term gas flow measurement in distribution systems.
7. Gallon (US)/Minute (gal (US)/min): Common in US water systems.
8. Gallon (UK)/Minute (gal (UK)/min): Used in the UK for liquid flow measurements.
9. Gallon (US)/Hour (gal (US)/h): Measures long-term water flow in agriculture.
10. Gallon (UK)/Hour (gal (UK)/h): Used in the UK for long-term liquid flow measurements.

The spray volume is greatest in the middle of the spray pattern and gradually decreases towards the edges, forming a mountain-shaped distribution curve. 
This "mountain" flow distribution nozzle provides the highest impact force, making it ideal for applications requiring concentrated impact, such as cleaning surface dirt. However, due to insufficient coverage at the edges, it is not suitable for applications requiring even coating. 
To improve edge coverage, the nozzle spacing can be reduced, allowing the spray patterns of adjacent nozzles to overlap, thus improving overall coverage.

The spray maintains an even and higher flow in the middle, with relatively lower flow at the edges, forming a plateau-like distribution. This pattern is suitable for applications requiring uniform coverage over a large area, such as coating and chemical treatments, providing consistent coverage. However, edge flow may still be insufficient.

The spray volume is greatest at the edges of the spray pattern, with relatively less in the center, forming a ring or donut-shaped distribution. 
This pattern is ideal for applications where avoiding excessive wetting of the central area is crucial, such as in precision spraying or specific chemical reactions. 
It is important to adjust the spray angle and distance to ensure that the edge areas do not become overly concentrated.
