变量名称: flow_switch_hysteresis
变量ID: 0x4501
变量标签: Hysteresis (0.1-10.0)
变量描述: If the hysteresis is set to 5%, no change of the Discrete Output state occurs when the flow rate is within +-5% of the setpoint. If the setpoint is 100 lb/min and the first reading is below 95 lb/min, the flow switch turns On and will stay On until the flow rate rises above 105 lb/min. At this point it turns Off, and will stay off until the flow rate drops below 95 lb/min.
