It combines non-contacting ultrasonic technology, patented echo-processing techniques and proven application software to provide accurate level monitoring in liquids up to 15 m (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 device 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 device can be expanded by additional I/Os, more RAM, two channels, RS-485 or SmartLinx communications models as your 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). The integral telemetry interface (Modbus RTU/ASCII) allows remote control in real time.
- Key Applications: wet well/lift station control, weirs/flumes, open channels
Application of accessories
SITRANS LUC500 can be expanded to meet the requirements of a variety of applications.
Auxiliary I/O cards, RAM and data logging, dual-channel function and SmartLinx communications.
- Input/output cards
A single auxiliary I/O card can be installed in the SITRANS LUC500. The following I/O cards are available:- 2 analog inputs/2 analog outputs
- 4 analog inputs
- 4 analog outputs
- 8 digital inputs
- 8 digital inputs/2 analog inputs/2 analog outputs (wall mount only)
- Expanded memory card
The available RAM can be increased using this card. The data logging function is then available. - Two-channel function
A second measuring point is provided on the SITRANS LUC500 to permit dual-channel measurements. This function is made available by ordering a software access code. Please contact your Siemens representative for details. - Communications
The SITRANS LUC500 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 currently available:- PROFIBUS DP
