Oxygen flow meters are medical devices used to measure oxygen flow in hospitals. Its main function is to supply oxygen to emergency patients and hypoxic patients at an appropriate flow rate. It can provide accurate control and measurement of oxygen flow in various medical environments. But oxygen flow meters also play a vital role in industrial applications.
In industrial applications, oxygen flow meters help optimize processes, detect leaks and misuse. To ensure proper oxygen delivery. Thereby improving productivity, safety and efficiency. Oxygen flow meters are widely used in medical, industrial, laboratory and other fields. It determine oxygen supply and monitor oxygen consumption.
What is an Oxygen Flow Meter?
An industrial oxygen flow meter is a device that accurately measures the volume or mass flow of oxygen flowing through a system over a specified period of time. This is critical for a variety of applications. Including process control, optimization. And ensuring proper oxygen delivery in industries such as manufacturing and healthcare.
Oxygen flow meters provide accurate readings of oxygen flow by monitoring oxygen flow. This allows industries to optimize their processes, reduce waste and increase efficiency. Especially in applications such as water aeration or fish farms. Oxygen flow meters can also help detect leaks and oxygen misuse, preventing waste and ensuring safety.
Properties of Oxygen
Physical Properties
At standard temperature and pressure, gaseous oxygen is colourless and odourless. Its density is slightly greater than that of air, and it is compressible; changes in temperature and pressure cause fluctuations in volume, necessitating the installation of temperature and pressure compensation modules in gas flow meters.
At low temperatures, oxygen can be liquefied to form pale blue liquid oxygen. Liquid oxygen has a much higher density than gaseous oxygen and is incompressible; temperature differences can easily cause vaporisation and cavitation, placing high demands on the sealing and low-temperature resistance of cryogenic flow meters.
Chemical Properties
Oxygen in both gaseous and liquid states possesses strong oxidising and combustion-supporting properties, but is not combustible in itself.
High-pressure gaseous oxygen and cryogenic liquid oxygen are highly prone to spontaneous combustion and deflagration accidents upon contact with oils or organic substances.
Safety and Fluid Characteristics
High-velocity gaseous oxygen flows are prone to generating static electricity; liquid oxygen is highly volatile and prone to vapourisation, leading to a mixture of gas and liquid phases within the pipeline, which can severely compromise the measurement accuracy of instruments.
Furthermore, impurities such as dust and water vapour within the medium can damage sensor components; therefore, specialised flowmeters must be selected according to the specific operating conditions of either the gaseous or liquid state.
Types of Industrial Oxygen Flow Meters
Vortex Flow Meter
Vortex flow meter uses the Karman vortex principle. It measures the fluid velocity by detecting the vortex frequency generated by obstacles in the fluid. It provides accurate flow measurement.
Vortex flow meters can be used to measure other gases such as oxygen, nitrogen, carbon dioxide and natural gas. They are also suitable for measuring liquids and steam.
Vortex flow meters are simple in design and have no moving parts. They can measure a wide range of flow rates from low to high and are suitable for measuring oxygen and other gases at extreme temperatures.
Thermal Gas Mass Flow Meters
Thermal gas mass flow meters can be used to measure oxygen. They measure the mass flow of gases, including oxygen, by detecting changes in the temperature field as the gas flows through a heated area.
Thermal mass flow meters directly measure the mass flow of gases. Accurate oxygen flow measurement is critical. They are not affected by changes in temperature and pressure. They can be used for oxygen production in industrial environments, medical applications of oxygen delivery systems, etc.
Gas Turbine Flow Meters
Gas turbine flow meters can be used to measure the flow of various gases, including oxygen, in industrial pipelines. They measure gas flow by using a turbine rotor that rotates , due to the force of the flowing gas.
Gas turbine flow meters can be used in various industries to measure the flow of different gases, including oxygen. They provide accurate flow measurements of liquids and gases, including oxygen. And cryogenic turbine flow meters can be used for liquid oxygen.
Liquid Oxygen Flow Meters
Coriolis
Coriolis flow meters can be used to measure the flow of various fluids (including liquid oxygen) in industrial pipelines. They utilise the Coriolis force to induce deformation in the measuring tube, thereby detecting the mass flow rate of the medium.
Coriolis flowmeters are suitable for use across a wide range of industries to measure the flow of various fluids, including liquid oxygen. They are capable of accurately measuring the flow of both gases and liquids (including liquid oxygen), whilst cryogenic Coriolis flowmeters are specifically designed for flow measurement in liquid oxygen applications.
Orifice Flowmeters
Orifice flowmeters are used to measure the flow of various fluids (including liquid oxygen) in industrial pipelines. They convert flow values by utilising the displacement signal generated when the fluid impacts the target.
Target flowmeters can be used across various industries to measure the flow of a wide range of fluids, including liquid oxygen. They are capable of accurately measuring the flow of gases and liquids (including liquid oxygen), whilst cryogenic-rated target flowmeters are suitable for flow measurement in liquid oxygen pipelines.
