Level measurement
Continuous level measurement — Ultrasonic controllers
SITRANS LUC500
■ Overview
■ Application
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 signaling
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.
SITRANS LUC500 is a complete ultrasonic level controller for
monitoring and control of water distribution and wastewater
collection systems, with energy-saving algorithms.
■ Benefits
• Monitoring and control in one device
• Integral telemetry interface (Modbus RTU/ASCII)
• Patented algorithm for calculation of pumped volume within
5 % accuracy
• Logging of pump runtime and number of pump starts
• Expandable with I/Os, RAM for data logging, dual point,
SmartLinx communications, and RS 485 interface
• Simple system configuration and diagnostics with Siemens
Dolphin Plus Windows-based software
• AC or DC power supply
• SITRANS LUC500 is available for rack mount, panel mount or
wall mount
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
- Allen Bradley Remote I/O
- DeviceNet
