Read： 488 Time：19months ago Source：Transform the World with Simplicity

A nozzle flow meter is an instrument that determines flow by measuring the velocity of a fluid in a nozzle. It is widely used in the flow measurement of various fluids, including liquids and gases. This article will introduce the working principle, characteristics and application scenarios of the nozzle flowmeter in detail. The working principle of

1.

nozzle flow meter calculates the flow rate by measuring the speed of the fluid in the nozzle. As the fluid passes through the nozzle, its velocity increases, but at the same time the cross-sectional area of the fluid decreases, keeping the flow constant. According to the continuity equation, the magnitude of the flow rate is inversely proportional to the flow rate and the cross-sectional area. The flow rate can be calculated by measuring the velocity and cross-sectional area of the fluid in the nozzle.

2. features

1. High precision. Nozzle flow meters are suitable for the measurement of various fluids, with an accuracy of more than 0.5%, which is more accurate than other flow meters.

2. Simple structure. The nozzle flowmeter has only one nozzle and several auxiliary parts, which is simple in structure and easy to install and maintain.

3. wide applicability. Nozzle flow meters are suitable for the measurement of liquids and gases of various viscosities, pressures and flows, and are widely used in petroleum, chemical, aviation and other fields.

3. application scenarios

1. Petroleum industry. Nozzle flow meters are widely used in flow measurement in the fields of oil drilling, transportation and storage.

2. Chemical industry. The nozzle flow meter can be used to measure various chemical fluids, such as acid, lye, organic matter, etc.

3. Aerospace industry. Nozzle flow meters can be used to measure the flow and mass flow of liquid fuel or gaseous gas injection.

4. Medical industry. Nozzle flow meters can be used to measure the flow of gases such as oxygen and nitrogen, and are commonly used in medical equipment such as ventilators and oxygen therapy.

In summary, the nozzle flowmeter is a flow measurement instrument with high precision, simple structure and wide applicability. Its working principle is to calculate the flow rate by measuring the speed of the fluid in the nozzle. It is widely used in many industries, such as petroleum, chemical, aviation, medical and other fields.
