Advanced gas mass flow controller work test report

Advanced gas mass flow controller work test report

MFC controls gas flow based on the operation of a flow meter and proportional valve under a PID control algorithm. The PID algorithm used by MFC generally has a dynamic adjustment function, dynamically adjusting according to different operating conditions to achieve rapid flow switching (generally response time <1s) and stable output of the set flow.

Detailed explanation of the functional characteristics of thermal mass flow meters

Detailed explanation of the functional characteristics of thermal mass flow meters

Thermal mass flow meters are a new type of high-temperature, low-pressure measuring instrument, widely used in the petroleum, chemical, aerospace, metallurgical, food, and papermaking industries. Thermal mass flow meters have a well-designed, high-performance temperature control system and are equipped with an advanced intelligent digital display that can directly input the mass or material density of the hot fluid. Working principle of thermal mass flow meter:

Introduction to the selection, use, and maintenance of thermal mass flow meters

Thermal mass flow meters, also known as calorimetric mass flow meters, are instruments used to measure the mass flow rate of various gases. The basic principle is to use an external heat source to heat the fluid being measured, and the temperature difference caused by the fluid flow reflects the mass flow rate of the gas. With the continuous development of science and technology, thermal mass flow meters have been widely used in many fields of scientific research and production. However, due to improper selection or use by users, instruments purchased at a high price often fail to fully achieve their expected measurement and control effects.

Applications of gas mass flow in the laboratory industry

Applications of gas mass flow in the laboratory industry

The Qingdao Xinsheng MFM-50 series gas mass flow meter is specifically designed for high-precision measurement of gas flow. This series of flow meters uses industry-leading flow sensing chips, combined with an aviation aluminum polished gas flow path design, and the company's core calibration and compensation algorithm to achieve high-precision flow measurement of various clean, dry, and non-corrosive gases. The typical accuracy of this product is 1% within 20 SLM and 1.5% for 50 SLM, and the turndown ratio is better than 100:1. The range of this series of products is selectable from 100 SCCM to 800 SLM (other ranges can be customized), and it is equipped with an LCD display, digital and analog outputs, making it easy for users to debug on-site and remotely. This product is low-cost, easy to install, and does not require additional temperature and pressure compensation, making it suitable for inert gas metering in the laboratory industry.
