Thermal Mass Flow Meter

  Digital flow meters used to measure industrial oxygen flow rate are many times referred as Oxygen Flow Meters. It is critical to select an appropriate flow meter for measuring and monitoring oxygen flow. For industries producing oxygen, there is a requirement of an accurate flow meter, because oxygen tanks or tankers are filled with known volume (the pressure is defined), and the manufacturer bills based on the volume of gas. Let us see some industrial applications of Oxygen Flow Meter. 1-     Chemical Industry- In its purest form, oxygen is used in many important chemicals such as ethylene oxide and titanium dioxide. It is also used to increase the production capacity of oxidation processes. To strengthen the process and boost the output of chemical fertilizers, oxygen is primarily employed for the oxidation of raw gas in the manufacturing of synthetic ammonia. The high-temperature cracking of heavy oil is further example where oxygen is required. An Industr...

  Most industrial facilities require compressed air , which is one of the most expensive energy sources within a factory. Compressed air is costlier than steam. Furthermore, unlike steam, which is visible at the leaking spots, it is invisible when it seeps. Compressed air leakages consume more electricity than any other type of equipment.   How to measure Compressed Air flow rate? One of the popular Compressed Air Flow meters is a Thermal Mass Flow Meter. Whenever a fluid of a certain temperature is passed over any substance hotter than the fluid, the heat of the hot substance is taken away because of forced convection by the fluid, and the temperature of that substance drops. This fall in temperature is related to the mass flow of the fluid passing over the substance. If one can measure the amount of heat taken away by the flowing fluid one can calculate the mass flow rate   Features of Compressed Air Flow Meter- ·       ...

What is flow meter and mass flow meter? A flow meter is a tool for determining the volume or mass of a gas or liquid. Flow meters are called by a variety of names depending on the application or functionality, including flow gauge, flow indicator, liquid meter, flow rate sensor, and so on. A mass flow meter , also known as an inertial flow meter, measures the mass flow rate of a fluid flowing through a tube. The mass flow rate is defined as the mass of a fluid passing through a fixed point in one unit of time.   Why flow measurement or monitoring is required? Flow monitoring is, without a doubt, one of the most common duties in any industrial setting. A variety of industrial processes need flow measurement of different liquids or gases for different reasons. These include billing to the user, accurate metering to mix exact quantities, avoiding wastages, filling the exact volume of gas or liquid in containers, custody transfer, and so on.     Is flow measurement or monitor...

What is a Steam Flow meter?   A steam flow meter is a device that measures steam flow rate, primarily of saturated and superheated steam, as well as mass flow rates of boiler feed water in closed conduits. It can be used as a heat energy transfer meter to measure thermal energy utilising a variety of fluids as heat transfer medium (including thermic fluids / thermic oils). Steam Flow Meter gives the information you need to run a plant or a building operation efficiently, giving vital inputs like how much steam is being used and how much it is costing. Steam flow meters are helpful in evaluating the performance of the system and can provide useful data in assessing boiler performance, calculating boiler efficiency, and tracking the amount of steam required by the system. In some systems, steam flow meters offer a measurement signal for the boiler control system. Additionally, steam flow meters can be valuable in benchmarking efforts.   Why steam measurement is important? ...

  About- Thermal mass flow meters , also known as thermal dispersion or immersible mass flow meters, are used to measure total mass flow rate of a fluid, primarily gases, flowing through closed conduits.   It is a direct mass flow meter with no moving parts. Theory of Operation- A  Thermal Mass Flow Meter  contains two temperature sensors for this purpose. Single sensor measures the fluid temperature as a reference. The second sensor is heated and has a constant temperature differential relative to the main sensor. When the flow of air/gas starts heat is taken absent from the warmer sensor. The quantity of heat taken away is having a direct relation with the mass velocity of the fluid. That is how it is a straight mass flow meter. Being a through mass flow meter, it does not require any pressure and temperature compensation. Types- There are two types of Thermal Mass Flow meters:   1-       Thermal Dispersion/Immiscible Ty...
