自动排水装置

支持液位检测的气动控制解决方案

ARO®自动排水装置为Pro和EXP隔膜泵提供自动开/关控制系统。借助气控液位传感器,可轻松地将液位控制在所需范围内。自动排水装置可防止泵干运转,从而减少监控人工和空气消耗。

The ARO® Automatic Dewatering System offers automatic on/off controls for Pro and EXP diaphragm pumps.  A pneumatically controlled Liquid Level Sensor is used to easily control the fluid level within a desired range.  The Automatic Dewatering System will limit the monitoring labor and reduce air consumption by avoiding dry running of the pump.

特点

  • 设计简单、易于安装和使用
  • 全气动操作消除了电气火花风险
  • 高/低液位控制可使液体保持在既定液位之间
  • 通过避免泵干运转来减少空气消耗
  • 带直装式液位传感器的便携式系统
