Thermal mass Flowmeters are designed to use the thermal properties of the fluid which is being measured. The typical industrial flow meter has two sensors one which is heated and another which remains unheated. This Device is accurately designed to measure the temperature of the fluid. It has a valve that allows the fluid to enter for it to be evaluated by the sensors. The heater sensor receives the heat but as heat increases some are lost in the flowing fluid However, the temperature measurements in the flow sensor take a record of this heat.
The fluid flow is determined by the heat input used by the transmitter and temperature measurements.Thermal dispersion flow metersare usually used in the gas flow because of their reliability and efficiency,it is a kind of digital mass flow meter.
When determining the lost temperature emphasis is laid upon the thermal properties of the fluid and the design of the sensor. These variations can be facilitated by various temperature ranges and pressure changes. Therefore, it is very important to know the composition of the fluid so that proper and accurate measurements can be taken.
In most cases, thermal gas mass flow meter works best in a clean fluid which is free from impurities,such as air flow meter orcompressed air flow meter. It is better to take the actual measurement of the fluid without necessarily mixing them up so that you can obtain accurate results. If the actual gas is not pure chances are that you will not get accurate measurements.
Thermal flow meter is a kind of great digital mass flow meters for gases and air. The mass flow measurement is not unaffected by temperature and pressure changes, its display readings directly indicate the mass flow rate of the gas, and it is installed in the pipeline to record the amount of gas flowing through it.It can be inline gas flow meter or insertion gas flow meter.
Gas mass flow meter can be used as blast furnace gas mass flow meter, coke oven gas mass flow meter, compressed air flow meter, nitrogen, natural gas, flue gas, chlorine gas , biogas, carbon dioxide and so on.
Relatively high initially costs,low price mass flow meter for gas.
It is only limited to non -abrasive clean fluids so that it can take accurate measurements.
Inaccuracy can be caused as a result of variation from calibrated values. Therefore, it is vital to know the thermal properties of the fluid.
Perhaps, the flowmeter is very sensitive which requires pure and specific thermal properties. However, this limitation does not apply to automotive engines.
It is normally used for clean gases such as nitrogen, ammonia, helium and other pure industrial gases. Other mixtures like biogas can only be measured after determining their respective composition. The good thing is that it is entirely dependent on thermal properties. It can also be used in petrochemical plants so long as the thermal properties of the gas are known. Some corrosive gases such as by sulfide can only be measured after determining its composition properties. This is quite an impressive system for those users who can measure pure gases because you are guaranteed accuracy in the values.
This instrument is very reliable in mass flow measurements. The following are common applications.
Thermal mass flow meter price is determined by many factors, top brand mass flow meter such as Sierra ,Endress Hauser,Bronkhorst,FCI,Yokogawa sell excellent quality ,also high price. Silver Automation Instruments supplies cheap thermal mass flow meter with good quality, can be low-priced replacement or alternative of top brand ones. Silver Automation Instruments price varies from 750~1500 USD according to different specifications, inexpensive in line thermal mass flow meter & insertion thermal mass flow meter.
Non-abrasive fluids and those that are capable of coating the sensor can adversely affect the flow measurement. The sensor will have to be regularly cleaned which will increase its maintenance costs. Additionally, if the components vary from the calibrated values it can make the device to be highly inaccurate. It is not suitable for fluid which has varying compositions. Gases with droplets and aerosols also compromise the functionality of thermal flow meter because they require large energy to heat up.
Therefore, when using this device it is important to stick to known specifications so that it can work optimally. Ensure the purity of the fluids is always maintained to avoid inaccuracy. This will help in accurately calculating the mass flow rate. Some industries require precise accuracy so that it can help in the management and monitor of its systems.
