Flygt MultiTrode replacement?
A complete guide to the Flygt MultiTrode level sensing system, its use in wastewater pumping stations and the FOGRod® multi-electrode replacement solution.
MULTI-ELECTRODE LEVEL DETECTION
What was the Flygt MultiTrode?
The Flygt MultiTrode was a conductive liquid level sensing system widely used in water and wastewater applications. MultiTrode probes provided multiple level sensing points along a single probe assembly.
The standard MultiTrode arrangement used multiple individual conductive sensors positioned at different levels. These sensors could be assigned to functions such as pump start, pump stop and high-level alarm.
This made the system particularly useful in wastewater pumping stations where several operating levels needed to be monitored from one installation.

HOW IT WORKED
Conductive level sensing
MultiTrode systems used the electrical conductivity of the liquid being monitored to determine when individual sensor points were submerged.
Liquid reaches sensor
As the wastewater level rises, individual conductive contacts become submerged.
Level is detected
The controller detects conductivity through the relevant sensor and interprets the corresponding level.
Equipment responds
The detected level can be used to operate pumps, trigger alarms or provide other control functions.
WASTEWATER APPLICATIONS
Typical MultiTrode level functions
Multiple sensor points allowed different operating levels to be configured within the pumping station.
Depending on the installation, sensor points could be used for functions such as pump off, lead pump start, lag pump start and high-level alarm.
IMPORTANT FOR EXISTING INSTALLATIONS
Flygt MultiTrode has been discontinued
Xylem discontinued its Flygt-branded MultiTrode products in January 2025. This means operators and contractors maintaining existing MultiTrode installations may need to consider alternative level sensing equipment when probes or associated components require replacement.
FOGRod® has been developed as a modern multi-electrode solution for wastewater applications where a MultiTrode-style level sensing arrangement is required.
THE FOGROD® SOLUTION
