Metering Pump Digital Stroke Controller

Metering pump stroke controller can achieve 0-100% manual/automatic metering pump stroke length locally/remotely, through the percentage of manual input or received control signal, automatically adjust the stroke position to adjust the metering pump stroke length, and finally adjust the metering pump output flow, to achieve the purpose of automatic control Stroke controller with local percentage and analog flow (based on calibrated flow conversion) display, control adjustment and maintenance is easy.

  Main Features:

• Adjustment range: 0-100%.

• No external auxiliary control equipment is required.

• Automatic stroke adjustment does not affect pump pulse.

• High adjustment precision, and provide flow calibration function.
