The Case Drain Flow Meter was designed specifically for monitoring case drain and pump performance and identifying when maintenance is required. The rugged, weather-proof design allows for outdoor installation and wash-downs, unrestricted mounting (horizontal, vertical, and inverted), as well as years of maintenance-free performance. The meter specs are targeted to case drain monitoring allows for operation up to 1,000 psi and is offered in NPTF aluminum ports.

Applications include:

  • Case drain monitoring
  • Pump performance monitoring
