Summary
In scientific research, production process control, quality management, economic accounting, and trade handover, the fluid quantity involved is generally mass, only Shandong Miniature Thermal Mass Flow Meter The measured volumetric flow rate of the fluid cannot meet people's requirements, and it is usually necessary to try to obtain the mass flow rate of the fluid. In the past, the mass of the fluid could only be obtained indirectly through correction, conversion, and compensation after measuring the parameters such as temperature, pressure, density, and volume of the fluid. This measurement method has many intermediate links and it is difficult to guarantee and improve the accuracy of mass flow measurement. With the development of modern science and technology, Shandong Miniature Thermal Mass Flow Meter of appearance has promoted the progress of flow measurement technology.
When a fluid flows in a rotating pipe, it will exert a force on the pipe wall, Shandong Miniature Thermal Mass Flow Meter is discovered by Coriolis in 1832 when studying turbines, it is called Coriolis force. In 1977, based on this principle, Shandong Miniature Thermal Mass Flow Meter 。 Shandong Miniature Thermal Mass Flow Meter based on the Coriolis force. The sensor has two parallel flow tubes inside, with a drive coil in the middle and detection coils at both ends. When the excitation voltage provided by the transmitter is applied to the drive coil, the vibrating tube vibrates in a reciprocating cycle. When the fluid medium in the industrial process flows through the vibrating tube of the sensor, a Coriolis force effect will be generated on the vibrating tube, causing the two vibrating tubes to undergo torsional vibration. The detection coils installed at both ends of the vibrating tube will generate two sets of signals with different phases. The phase difference between these two sets of signals is the mass flow rate of the fluid flowing through the sensor, and the computer calculates the mass flow rate through the vibrating tube.
When different media flow through Shandong Miniature Thermal Mass Flow Meter the main vibration frequency of the vibrating tube is different, so the density of the medium can be calculated, and the platinum resistance installed on the vibrating tube of the sensor can indirectly measure the temperature of the medium.
Warm prompt, Shandong Miniature Thermal Mass Flow Meter directly measure the mass flow rate of the medium passing through the flow meter, and can also measure the density of the medium and indirectly measure the temperature of the medium. Because the transmitter is an intelligent instrument with a single-chip microcomputer as its core, it can derive more than a dozen parameters for users based on the above three basic quantities. Shandong Miniature Thermal Mass Flow Meter Flexible configuration, powerful functions 'High performance-price ratio, it is a new generation of flow meter.'
A flow measuring instrument that measures the mass flow rate in a measuring pipe. When the parameters of the measured fluid, such as pressure and temperature, change greatly, if only the volumetric flow rate is measured, the change in fluid density will bring a large measurement error. In volumetric and Shandong Miniature Thermal Mass Flow Meter the density of the measured fluid may change 30% of the change, which will lead to 30~40% error. With the improvement of automation level, many production processes put forward new requirements for flow measurement. Chemical reaction processes are controlled by the quality of raw materials. The heating and cooling effects of steam and air flow are also proportional to the mass flow rate, therefore, Shandong Miniature Thermal Mass Flow Meter is an important flow measuring instrument.
