Overview
- Effeciently controls the inlet valve and blow-off valve when the compressor starts and stops.
- During steady operation, controls the inlet valve so that the amount of discharged compressed air becomes constant (flow control)
- Surging: Load decreases, the amount of discharge flow and pressure drop, and a limit is exceeded, possibly destroying the compressor.
In such cases, the YS1700 Single-loop Controller switches smoothly and automatically between flow control and pressure control to prevent surging.
* A compressor is an important device in every kind of factory that is used to compress air, oxygen, hydrogen, and other source gases and process gases.
- Selector Control (YS Specific Algorithm)
Allows for automatic switching between two differing control factors, flow volume and pressure. - High Speed Control Interval (50 msec)
Keeps up with fast process changes, enables smooth switching control. - User Programming
Enables start-stop sequences and can be customized in various ways for compressors.

上游
上游業包含海上和陸上活動，包括井口自動化，分餾，完井和分離，回收和製備地下或水下原油和天然氣。
當石油被帶到地表時，在運輸之前必須將其分離。在三相分離中，一級和二級分離階段通常分佈有氣體流量，水流量和油流量，氣體的輸送需要管道，並且在輸送之前的上游階段需要進行分餾。液體需要通過罐和管道輸送並處理，這就需要精確的液位測量。
