The Probe is a short-range integrated ultrasonic level transmitter, ideal for liquids and slurries in open or closed vessels.

The transducer is available in PVDF copolymer, making the device suitable for use in a wide variety of applications. The Probe is easy to install and maintain, and can be quickly removed for cleaning as required by the food, beverage and pharmaceutical industries.

The reliability of the level data is based on the Sonic Intelligence echo processing algorithms. A filter discriminates between the true echo and false echoes from acoustic or electrical noises and agitator blades in motion. The ultrasonic pulse propagation time to the material and back is temperature-compensated and converted into distance for display, analog output and relay actuation.

Key Applications: chemical storage vessels, filter beds, mud pits, liquid storage vessels, food applications

• Easy to install, program and maintain
• Accurate and reliable
• Sanitary models available
• Patented Sonic Intelligence® echo processing
• Integral temperature compensation

The Siemens SITRANS LUT400 series controllers are compact, single point, long-range ultrasonic controllers for continuous level, or volume measurement of liquids, slurries, and solids, and high accuracy monitoring of open channel flow.

• The SITRANS LUT400 comes in three different models, depending on the application, level of performance and functionality required:
• SITRANS LUT420 Level Controller: Level or volume measurement of liquids, slurries, and solids, as well as basic pump control functions, and basic data logging capability
• SITRANS LUT430 Level, volume, Pump and Flow Controller: Includes all features of the LUT420 plus a full suite of advanced pump control and alarm functionality, open channel flow monitoring, and basic flow data logging capability

Echomax® XRS-5 ultrasonic transducer provides reliable, continuous level monitoring of liquids and slurries in narrow lift stations/ wet wells, flumes, weirs and filter beds using a beam angle of just 10° and a CSM rubber face.

The XRS-5 is non-contacting with a measuring range from 0.3 to 8 m (1 to 26 ft). Advanced echo processing ensures reliable data even in conditions with obstructions, turbulence and foam.

The hermetically sealed CSM rubber face and the PVDF copolymer enclosure are designed for maximum resistance to methane, salt water, caustics and harsh chemicals common to wastewater installations. With an IP68 degree of protection, this rugged sensor is fully submersible in the event of flood conditions. Use a submergence shield if full submergence is possible in the application. A submergence shield will maintain a high level reading output during submerged conditions.

The low-cost XRS-5 transducer is compatible with a full range of Siemens controllers, from a basic system for high/low alarm or simple pump control, up to advanced control systems with communications, telemetry and SCADA integration capabilities.

Key Applications: wet wells, flumes, weirs, filter beds.

• Narrow beam angle of only 10°
• Chemically resistant PVDF copolymer enclosure and CSM rubber face
• Measuring range: 8 m (26 ft) for measurement of liquids and slurries.
• Fully submersible: IP68 degree of protection

Easy installation with 1" NPT or R 1" BSPT connection
