Metering pumps and flow meters are two different devices that differ in their functions and uses.
Metering pump:
Features:Metering pumps are primarily used to accurately deliver the exact amount of liquid, often for adding pharmaceuticals, chemicals, or other liquids that require a precise dose.
How it works:Metering pumps typically achieve precise volume control by means of plungers, diaphragms, or gears to ensure that the amount of liquid being conveyed per unit of time is accurate.
Applications:It is mainly used in water treatment, chemical, pharmaceutical and food processing fields, where precise control of liquid dosage is required.
Flow meter:
Features:Flow meters are used to measure the flow rate of liquids, gases, or vapors in pipes, i.e. flow.
How it works:Flow meters work on a variety of principles, including vortex, electromagnetic, ultrasonic, liquid mass measurement, and other techniques to measure the volume or mass of fluid passing through a pipe.
Applications:It is widely used in various industrial processes, such as petrochemical, water treatment, food and beverage production, etc., to ensure accurate monitoring of fluid flow during production and transportation.
When to use the flow meter:
Flow meters can be used in any situation where fluid flow needs to be monitored, controlled, or recorded.
In industrial processes, flow meters help ensure that fluid flows at the right rate in production to ensure product quality.
In practical life, flow meters can be used to measure the consumption of water, gas, or other liquids and gases in a household for resource management and expense metering.
Overall, metering pumps are primarily used to precisely control and deliver liquid doses, while flow meters are used to measure the rate at which fluids flow. In some applications, both may be used together to ensure accurate metering and flow monitoring of liquids during production and handling.
