主要功能
1、測量功能：瞬間流量計算、流量累計、自動調零和調間隔、自動零點跟蹤和電流輸出信號。
2、監測功能：可提供狀態提示、過程報警、設定錯誤、設備故障、高流量報警、高負載報警、低負載報警、高控制偏差。
3、自動控制給料功能：具備兩個獨立的控制電流環。第一個控制電流環通常用于控制給料量，第二個電流環通常用于控制其他設備，控制方式為PID=比例+微分，可控制的過程變量為給料量、速度或皮帶秤載荷、流量設定點可通過鍵盤輸入、串行通訊或外部模擬信號設定。控制輸出為4-20mA電流環。
Major function
l, measurement: instantaneous flow rate calculation. the cumulative flow, automatic zero adjustment and adjustable interval, automatic
ze ro tracking and current output signal
2. monitoring function: provide state prompt, process alarm, setting error, equipment failure, high flow alarm, alarm. low alarm, high load
high load deviation control.
3, automatic control feeding function: with two independent control current loop. The first current loop control is normally used to control
the feeding amount. the second current loop is often used to control other devices. control PID= proportional plus differential and process
variables can be controlled for to feed, speed or load of belt weigher. flow set point can be input through the keyboard, serial pass or
external analog signal set
To control the output current of 4-20mA ring.
