  • LT300 – compact, cost-effective, and ideal for general pump stations 
  • LT60 –   cost effective high mechanical robustness for demanding application with open diaphragm e.g. for wastewater with lot of particles  
  • LT100/LT600 – enhanced accuracy, high chemical resistance solid diaphragm in different steel material. 
  • LT11 – high-performance model two sensor technology a unique innovation for deep wells and demanding application, can be adjusted locally, via Hart or Modbus, with relay option for pump control or alarm.  

Built-in Safety – Lightning Protection as Standard

Except LT300 all installed models can be equipped with integrated surge protection, no need for external protectors or costly enclosures.  

Autozerofunction

All Pondus level transmitters come with our unique Autozero function – as standard. This feature allows instant re-zeroing of the sensor without dismounting or returning it for calibration.

Customer Case

Smart, Safe, and Scalable Level Measurement Meeting Different Needs with One Trusted Partner 

A regional utility company needed to modernize level measurement across a wide range of water and wastewater sites — including pump stations, retention basins, deep wells, and chemical tanks. Their requirements varied significantly:  

  • Low-cost solutions for simpler installations 
  • High safety and redundancy for important processes 
  • Intrinsically safe installations 
  • Deep-well measurement  
  • Minimization of service and downtime 
  • Built-in protection against lightning and voltage surges 

Innovation that Saves Money – LT11 with absolute sensor

Deep well measurement – often requiring long vented cables that are expensive and sensitive to condensation and blockage. 

The solution was LT11, equipped with a built-in absolute pressure sensor: 

  •  No need for a vented reference tube 
  • Lower cable cost and simplified installation 
  • Reliable readings even in humid or flooded cable ducts 
  • Designed specifically for wells up to 100+ meters deep 

 

“We now have a system that fits every site – without having to compromise or customize. Pondus gave us proven technology and clever design in one package.”
