The Siemens SITRANS LUC 500 ultrasonic level controller is a complete, cost-effective solution for monitoring and control in water distribution and wastewater collection systems.

It combines non-contacting ultrasonic technology, patented echo-processing techniques and proven application software to provide accurate level monitoring in liquids up to 15m (50 ft). It also effectively monitors flow in flumes, weirs, and open channels. Five relays control any combination of pumps, gate valves, and alarms. Further advantages include fault signalling and data logging for trend analysis. It can log the time, date and volume of up to 20 occurrences of combined sewer overflows (CSO).

The basic level controller has 8 digital inputs, 5 digital outputs, 1 analog input, 1 ultrasonic level point, differential/average capability, and one RS-232 interface with Modbus RTU/ASCII protocol. The Siemens SITRANS LUC500 can be expanded by additional I/Os, more RAM, two channels, RS-485 or Smartlinx communications modules as needs grow.

It integrates seamlessly with SCADA or DCS systems or a PLC system to provide remote access to all system parameters (pumped volume, pump runtime, pump status, etc.) The integral telemetry interface (Modbus? RTU/ASCII) allows remote control in real time.

The ultrasonic level controller is easy to install and configure, with fast start up, reliable performance, and low maintenance

  • Monitoring and control in one device
  • Integral telemetry interface (Modbus RTU/ASCII)
  • Patented algorithm for calculation of pumped volume 5% accuracy
  • Logging of pump runtime and number of pump starts
  • Expandable with I/Os, RAM for data logging, dual point, and SmartLinx? communications and RS-485 interface
  • Simple system configuration and diagnostics with Siemens Milltronics? Dolphin Plus Windows based software
  • AC or DC power supply
  • EnviroRanger LUC500 is available for rack mount, panel mount or wall mount

Wall Mount
Suitable for outdoor or indoor mounting. Typically used for remote lift stations or where the most number of I/O options are required.

Panel Mount
Suitable for indoor mounting. Typically used in control rooms alongside other panel-mounted electrical equipment or where space is limited.

Rack Mount
Suitable for indoor mounting. Typically used in control rooms where rack mounting is preferred.

The LUC500 can be expanded to meet the requirements of a variety of applications. Auxiliary I/O cards, RAM and data logging, dual point function, and SmartLinx? communications.

  • Input / Output Cards
    A single Auxiliary I/O card can be installed in the LUC500. The following Auxiliary I/O cards are available:
    • 2 Analog Input / 2 Analog Output
    • 4 Analog Input
    • 4 Analog Output
    • 8 Digital Input
    • 8 Digital Input / 2 Analog Input / 2 Analog output (wall mount only)
  • Expanded Memory Card
    The available RAM can be increased using this card. The data logging function is then available.
  • Dual Point Function
    A second measuring point is provided on the LUC 500 to permit dual-point measurements. For existing installations, this function is made available by ordering a software access code. Dual point is available as a configuration option for new units. Please contact your Siemens supplier for details.
  • Communications
    The LUC 500 is offered with Modbus RTU/ASCII as a standard feature. Further industrial communications protocols are available with the addition of an optional SmartLinx card. The following protocols are available:
    • Profibus-DP
    • Allen Bradley? RIO
    • DeviceNetTM
