What Is GPM in Flow Meter?
GPM is the abbreviation for gallons per minute and is used to indicate the volume of liquid flowing through a pipe diameter in one minute. Is a unit of measurement used in flow meters. Essentially, it tells you how many gallons of liquid are moving through the pipe per minute. GPM is widely used in a variety of industries and applications such as water supply systems, irrigation and fluid transfer. Understanding GPM in a flow meter is important for both selecting and using a flow meter.
flow measurement units
In the world of flow meters, various units of measurement are used to quantify the flow of liquids or gases. These units help to ensure precise flow control and monitoring across industries. Let’s take a look at some of the commonly used flow meter units:
Gallons per Minute (GPM): As we discussed earlier, GPM is a popular unit for measuring liquid flow, especially in the United States, where the imperial system is widely used.
Liters per Minute (LPM): LPM is another unit for measuring liquid flow, commonly used in countries that follow the metric system. One GPM is approximately equal to 3.785 LPM.
Cubic Meters per Hour (m³/h): This unit measures the volume of gas or liquid flow per hour and is often used in large-scale applications, such as water supply networks and industrial processes.
Standard Cubic Feet per Minute (SCFM): SCFM is a unit for measuring gas flow rates. It represents the volume of gas flowing per minute, corrected to standard conditions of temperature and pressure.
Cubic Feet per Minute (CFM): Similar to SCFM, CFM is a unit for measuring gas flow rates, but without adjusting for temperature and pressure.
By understanding these commonly used flow meter units, you can better select and utilize flow meters for your specific application, ensuring accurate measurements and optimal performance.
