EL-F / EL-T Special Solutions

Pleiger EL-T-HFO

Electronic level sensor, submerged type, for fuel oil with temperatures up to 100ºC.

Pleiger EL-T-PT100

Electronic level sensor, submerged type, with internal PT100 temperature measuring element.

Pleiger EL-F-0.1%

Electronic level sensor, flanged type, with high measurement accuracy.

Electropneumatic Tank Level System

Pleiger PEL-D2

One measuring system – two system advantages!
The PEL-D2 type combines the advantages of the electrical and the electropneumatic measuring.

  • Low-cost installation
  • Short measuring tube length
  • Connection in ring line structure to the supply air
  • Clean pneumatic filling level measurement


  • Diaphragm safety valve PEL-C-S with air fine regulation valve
  • Electronic level sensor (IP68)

Pleiger PEL-C

The original remote tank measurement, now equipped for the future. All measuring equipment units are collected together in a central transmitter cabinet. In this way, they are optimally protected against dirt accumulation and vibration, and are accessible for easy maintenance.


  • P/E-Transmitter PE12
  • Pneumatic control block with test function, fine regulation valve, control valve (for remote control)
  • Air flow meter
  • Diaphragm safety valve PEL-C-S

Radar Measuring Systems For Tankers

Radar Sensor

The contact-free Pleiger radar sensor is characterized by the highest level of resistance to chemical reactions due to its high-quality PTFE-coated antenna and by an extremely robust design when faced with temperature and pressure variations.


  • Contactless
  • Highly Accurate
  • One wetted material only
  • No additional sealing necessary
  • Additional focusing by conical design
  • Unaffected by temperature, pressure and product properties
  • High chemical resistance and easily cleanable antenna system due to PTFE-coating

Multi Flange

By using the world’s smallest level radar unit, the installation of the entire cargo measurement technology is possible on a single ANSI 12″ measurement flange. This means simpler project planning and installation, easier verification and simpler and lower-cost maintenance.
Consists of:

  • Compact 12” decks flange
  • 95% / 98% alarm with vibration level switch
  • Ullage measuring with radar sensor
  • Tank pressure measurement with pressure sensor
  • Optional UTI (ullage, temperature, interface) connection

Integrated Solutions

Pleiger PCM for Tank Measuring Systems

The Pleiger Control Module (PCM) System combines several control and I/O modules, which are linked by means of fieldbus interface to a Supervisory Control And Data Acquisition (SCADA) system. Analog signals of the level sensors, as well as digital alarm contacts of limit switches, can therefore be transmitted to the system directly.

  • Input/Output modules IO8/8/4 for the recording of level sensors and limit switches.
  • Interface bus modules BI for serial connection to SCADA systems and visualization systems
  • Profibus DP and Modbus RTU Data exchange protocol
  • Redundant data link together with additional bus interface bus modules possible
  • Short-circuit-proof outputs and overload resistant inputs prevent damage to the module
  • Displays and diagnostic functions facilitate data acquisition and troubleshooting
