Application of mini CORI-FLOW (Pump System Case 1)
Application of mini CORI-FLOW (Pump System Case 1)
[Pump System Case 1] Gas or Liquid Precursor Delivery
In the vapor deposition process, various precursor fluids (regardless of whether they are gases or liquids) must be precisely controlled. The "mini CORI-FLOW(R) series high-precision mass flow controllers" are particularly well-suited for these demanding applications. Thanks to the "multi-range" feature, OEM customers do not need to maintain numerous types of instruments. This device allows for easy range changes, thereby providing a cost of ownership advantage. [Application Examples] - Applying mini CORI-FLOW(R) to additive dosing → Enables the easy construction of a compact and autonomous system. - Applying mini CORI-FLOW(R) to batch counters → Provides high precision, high speed, high repeatability, and a compact batch and dosing system.

basic information
【Application Examples】 [Application to Additive Distribution] ○ The master flow meter connected to FLOW-BUS (Broncost's field bus) measures the main fluid. ○ The slave instrument, preset to follow the master at a certain ratio, is also connected to FLOW-BUS. ○ When the main fluid changes, the slave instrument receives the changed output signal from the master via FLOW-BUS and follows accordingly. ○ The slave instrument recalculates its set values. ○ The PID controller of the slave instrument operates based on the new set values and supplies control signals to the pump driver. ○ As a result, the pump's rotation speed is controlled to regulate the flow rate of the additive to the new set value. [Application to Batch Counter] ○ Mass is measured, and the built-in PID controller drives the proportional valve. ○ External inputs are made to the analog input or digital interface (RS232 or field bus). ○ The desired batch amount is programmed as a limit value in the built-in counter. ○ When the counter reaches the limit value (batch), the valve is closed until the next reset. ● For more details, please contact us or download the catalog.
