3/14/2024 0 Comments Mass flow meter![]() Plug-in sensor applicable pipe diameter: DN80 ~ 6000mm (specify when ordering larger pipe diameter). If the pipe material cannot be welded (such as cast iron, PVC, glass fiber reinforced plastic, cement, etc.), the special fixture produced by our company can be used to fix the sensor on the pipe. Finally, the sensor Install on the valve and insert the sensor into the center of the tube (the insertion position of the sensor is determined at the factory). Then use a special tool to punch the pipe with a diameter of 22mm. Install a 1-inch stainless steel ball valve on the base. The installation process is to first weld a base with external threads on the outer wall of the pipe. Integrated plug-in thermal mass flow meter: plug-in sensors can be installed and maintained online. According to the type of flow sensor, it is divided into: plug-in type and tube type thermal gas flow meter. Thermal gas mass flowmeter consists of integrated flow converter and flow sensor. K1, K2, K3 are constants related to the physical properties of the gas. According to King’s law of thermal effects, there is a certain mathematical relationship between heating power P, temperature difference △ T (T1-T2) and mass flow Q. To maintain a constant temperature difference between T1 and T2, the heating power of T1 must increase. As the mass flow rate of the gas increases, the airflow takes away more heat, and the temperature of the sensor T1 decreases. When these two RTDs are placed in the measured gas, the sensor T1 is heated to a constant temperature difference above the gas temperature, and the other sensor T2 is used to sense the temperature of the measured gas. One is the mass speed sensor T1, and the other is the temperature sensor T2 that measures the temperature change of the gas. The sensor of the thermal mass flowmeter consists of two reference thermal resistors (platinum RTD). Thermal gas mass flowmeter is a meter that measures the mass flow of gas using the principle of heat conduction. ![]() If you are not sure whether you can choose a thermal mass flowmeter for your measurement conditions, please feel free to contact our Sino-Inst technical engineers! ![]() And many more… (Comments are welcome to add).Gas flow (velocity) measurement in heating ventilation and air conditioning systems.Mine ventilation or exhaust system flow,.Smoke flow (speed) measurement of smoked meat (CEMS).Combustion gas measurement in coal-fired boilers.Gas flow measurement in solvent recovery systems.Gas flow during semiconductor chip manufacturing process,.Carbon dioxide gas flow rate during beer production,.Aeration and chlorine measurement in water treatment,.Multi-component gas measurement biogas,.Gases Commonly Measured with Thermal Mass Flow Meters: We have compiled and summarized the media suitable for thermal mass flow meters for your reference: Thermal mass flow meters for liquids are also limited in their use for viscous liquids.īased on our many years of experience in gas measurement services. Plug-in thermal mass flow rate Gauge is more suitable for large diameter. Immersion thermal mass flow meter can measure low to medium to high flow rate (gas 2 ~ 60m / s). Thermal mass flow meter can measure low flow rate (gas 0.02 ~ 2m / s) and small flow rate. The use of pulsating flow will be limited. Thermal flow meters can measure flow in large pipes. Thermal flowmeters provide excellent accuracy and repeatability over a wide range of flow rates. Reduces maintenance and permits the use in demanding application areas, including saturated gas. In the place where the measured gas composition changes greatly, the measurement value will vary greatly due to the change of cp value and thermal conductivity, which will cause errors.įor small flows, the meter will bring considerable heat to the measured gas.įor the thermal distributed thermal mass flowmeter, if the measured gas deposits a scale layer on the pipe wall to affect the measured value, it must be cleaned regularly for the thin tube type instrument, it is more prone to blockage and cannot be used under normal circumstances. No pressure or temperature compensation required Multivariable – direct measurement and display of mass flow and fluid temperature
