一、概述
LU-50流量积算仪适用于各种液体、气体、蒸气的流量测量，并可根据测量的压力进行补偿运算，具有多种输入方式，可配接涡街等频率脉冲式传感器或其它0-10 mA输出 或4-20 mA输出的流量变送器。
LU-50流量积算仪采用查表的补偿方式，可以对过热蒸气、饱和蒸气进行高精度 的补偿运算，具有多种显示方式，可显示累积流量、瞬时流量、压力、温度频率、密度、时间，显示的刷新周期可任意设定。LU-50流量积算仪可根据输入频率的不同，设定十个不同的流量常数，按插值算法自动对流量常数进行校正。LU-50流量积算仪采用WATCHDOG电路，软件陷阱，冗余，数字滤波等技术，整机具有很强的搞干扰能力。
