Abstract: A turbine meter is supported within a housing and produces signal pulses proportional to flow. An injector valve to the input side of the meter is connected to a pressurized additive tank through a linear valve. The valve includes a tapered shaft axially positioned in a flow orifice. A converter converts the pulses to an analog signal. A set point generator establishes a scaled signal which is connected with a line pressure compensating signal and the analog signal to an amplifier to produce an analog error signal driving a servomotor to position the linear valve shaft and a feedback potentiometer. A slotted connection to the valve shaft permits relative axial shaft adjustment for accurate setting relative to the potentiometer. The feedback signal is summed with the error signal to correspondingly position the valve. The servomotor unit and the control valve are secured within the housing with the additive tank to be releasably secured to the top wall. A minimum flow valve is connected in the additive flow line to selectively stop flow of additive.
Abstract translation: 涡轮流量计被支撑在壳体内并产生与流量成比例的信号脉冲。 通过线性阀将通向仪表输入侧的喷射阀连接到加压添加剂罐。 该阀包括轴向位于流动孔中的锥形轴。 A转换器将脉冲转换为模拟信号。 设定点发生器建立一个缩放信号，该信号与线路压力补偿信号相连，模拟信号连接到放大器，以产生模拟误差信号，驱动伺服马达来定位线性阀轴和反馈电位器。 与阀轴的开槽连接允许相对轴向轴调整，以相对于电位器进行精确设置。 反馈信号与误差信号相加，以对应地定位阀。 伺服电机单元和控制阀被固定在壳体内，添加剂罐可释放地固定在顶壁上。 添加剂流路中连接有最小流量阀，以选择性地停止添加剂的流动。
