Summary
The semiconductor gas flow controller industry has a bright future because it offers many benefits to businesses, making it a favorite among customers. To help people learn more about it, let's discuss the advantages of semiconductor gas flow controllers. Hopefully, this will be helpful to many.
Many people are still unfamiliar with the basic information about semiconductor gas flow controllers. Therefore, as a manufacturer, we need to briefly explain. When using a semiconductor gas flow controller, you are likely familiar with flow measurement devices that measure mass flow in pipelines. When the pressure and temperature of the fluid being measured change significantly, measuring only the volumetric flow rate will also result in a large measurement error due to changes in the fluid density. In volumetric and differential pressure flow meters, the density of the fluid being measured can differ by 30%, which will lead to a 30-40% error in flow rate. In recent years, with the improvement of automation levels, many manufacturing processes have new requirements for flow measurement. Another important point is that the mass (rather than volume) of raw materials controls chemical reaction processes. The heating and cooling effects of steam and air flow are also proportional to the mass flow rate. Therefore, strict product quality control, accurate cost accounting, and fuel control for aircraft and missiles also require accurate mass flow measurement. The semiconductor gas flow controller is also an important flow measurement tool.
In fact, a semiconductor gas flow controller uses mechanical measuring elements to continuously divide the liquid into a known volume fraction and measures the volumetric flow rate of the liquid based on the number of times the metering chamber fills and discharges the liquid volume fraction. The semiconductor gas flow controller consists of a flow regulating valve, a manually adjustable flow orifice (equivalent to a static balance element), and a dynamic regulating device consisting of two discs, a spring, and a diaphragm. That is, it creates an automatically adjustable orifice plate (equivalent to a dynamic balance element). It can be used anywhere flow monitoring is needed. Therefore, everyone should know that the semiconductor gas flow controller is also a reliable device in the automation industry, chemical industry, and anywhere that requires flow monitoring in a safe, robust, and low-maintenance manner. Another point is that its flow measurement and control will not be affected by temperature or pressure fluctuations. For most flow measurement and control systems, it is difficult to avoid pressure fluctuations in the system and temperature changes inside and outside the environment. For ordinary flow meters, pressure and temperature fluctuations will cause large errors; for mass flow meters, they can usually be ignored. The flow measurement value can still be output as a standard electrical signal. This makes it easy to achieve digital display of flow rate, automatic metering of cumulative flow, automatic data recording, and microcomputer management.
The above article introduces some relevant information about the advantages of semiconductor gas flow controllers. Readers are encouraged to carefully review it. Of course, there is still much more information about it. We will continue to update it in the future.
