Precision Water Management with the Tunze Osmolator 3155

  • Designed to Ensure Perfect Water Levels
  • Redundant Protection Against Overfilling
  • Visual and Audible Alarms for any Irregularities
  • Strong Magnetic Mounts for a Secure Hold

 

Gone are the days of manual water top-offs. Experience hassle-free water level management with the Tunze Osmolator 3155. This time tested system ensures that maintaining perfect water levels is a seamless experience. It integrates an optical sensor with a float switch, offering not only reliability, but also redundancy to protect against overfilling the aquarium.

The optical sensor acts as the primary water level sensor, while the float switch is the backup. If water triggers the float switch, power is cut to the pump and an audible and visual alarm is triggered. In addition, there is a built-in maximum run time of 10 minutes that can also cut the pump's power. This can not only help prevent an overflow, but can also protect the pump if the auto top off reservoir has run dry.

 

Specifications:

Max Head Height: 7.0 ft

Tubing Diameter: 7mm OD | 4mm ID

Tubing Length: 3 Meters

Magnetic Holder: Suitable for sensors up to 10mm or 3/8"

 

For those with requirements for a higher head pressure pump, consider Tunze's Turbelle High Jet Pump as an ideal replacement for the stock osmolator pump.

 

What's Included?

Water Level Controller 5017 w/ Optical Eye & Float Switch

Low Voltage Pump

How long is the wire between the sensor and pump? Is there an extension if the RO source is further away?
Question by: Brett on Dec 7, 2023, 1:28 AM
Hi there, great question. The wire will be 3 meters long and unfortunately there is not an extension cord.
