Multi-Electrode Probe Technology - Ultra reliable, robust, simple and easy
-
Liquid level detection using conductivity via multi-electrode points along one 35mm diameter PVC probe
-
3, 5 and 10 electrode versions for multiple applications eg. wastewater, de-watering, bore holes, storm tanks, culverts etc
-
No specialist skills required to install or maintain. No laptops or apps as no programming or configuration required
-
EASY & SAFE INSTALLATION AND MAINTENANCE from above, NO confined space entry EVER required.
-
INSTALL - Simply fix bracket, connect up, lower and hang. Only 1 cable to pull through a duct
-
MAINTAIN - None in water applications, for wastewater simply pull up through the cleaning bracket on a service visit
-
No moving parts, no tangling or stiffening of multiple float cables reducing flooding and eliminating pump run on
-
Great for applications with limited spaces, narrow and cluttered wet wells etc.
-
Works in fatty, greasy, foaming wet wells, also works in heavy sludge
-
No witches hats to trip over and cumbersome rods to handle, everything in the well or culvert with one cable through the duct
-
10 year warranty, virtually unbreakable design
'The best pump in the world is only as good as it's control system'
FOGRod® is a multi-electrode conductivity probe designed by ex-MultiTrode Australia Engineers to directly replace the discontinued Xylem MultiTrode level probe. FOGRod design improvements over the MultiTrode probe include being unbreakable if dropped plus has a smaller diameter more flexible screened cable to protect against electrical interference.
Designed specifically for the water industry to deliver resilience and reliability by monitoring the level of water and wastewater effluent very simply and effectively.
Excellent solution for where space is limited. Hawker probes won't fit? Ball floats aren't suitable? Non-contact not an option? FOGRod is the answer.
Reduce call outs, reduce energy usage, reduce installation costs, increase safety as NO confined space entry EVER required
