Application of EDC-335 Massflow Controller and Meters
Gas Control During Fiber Fabrication
Optical fiber preform equipment, optical fiber drawing, and ribbon optical fiber preparation in the optical fiber industry. During the fiber drawing process, the composition and flow of the atmosphere need to be controlled to ensure the quality and performance of the fiber. Need to supply a certain amount of gas, such as protective gas, dry gas, etc. Optical fiber drawing MFC is used to control the flow rate and mixing ratio of the gas to provide the correct atmosphere environment. To ensure that the optical fiber preparation process is stable and repeatable.
Bioreactor Gas Flow Control
Accurate, repeatable and stable airflow is critical to a reliable biological growth process.Especially in R&D environments, a large range of gas flow variations is required to study optimal growth conditions. Benchtop bioreactors require compact gas flow instrumentation. For manufacturers who build bioreactors to customer specifications, there is a need to reduce the number of variations of various flow instrumentation to offset delivery time hurdles. Additionally, pressure data is required to inform bioreactor users of current process conditions.
Catalyst Evaluation Equipment
Catalyst development requires high temperature and pressure to prevent condensation of compounds and to analyze the chemical composition of exhaust gases from reactors. To find out under which conditions a catalyst has optimal performance for a particular chemical reaction, the high pressure range must be dealt with. In the application, the pressure must be accurately controlled and the pressure range is large. Also, the corresponding control device should be able to handle high pressure, high temperature and low flow. The product is perfectly adapted to the conditions in this application.
Gas Flow Control Applications in Analytical Instruments
A common factor in many analytical applications is the need for a small steady gas flow (flow range: 1-1000 sccm), since the gas flow and its changes are directly visible in the measurement, a stable gas flow is important. In analytical equipment, the carrier gas flow directly affects the measurement results. For example, the retention time of a substance in a chromatographic column depends directly on the stability of the fluid. When the flow fluctuates, so does the measurement. This product has short-term and long-term control stability.
