LLS-23

Never before offered in the aquarium industry the LLS Sensors allow for the measurement of water depth in inches or centimeters.  Available in four different sizes- 4″, 15″ 23″ and 35″ each sensor has a special place in helping understand the water level in the sump, aquarium, reservoirs, and other liquid-holding containers.  No longer does one need to physically look to observe how much water level is above or below a specific point, but now simply open the Apex Fusion App and observe.

The LLS sensor can connect to any available FMM port in the Apex System.  Liquid will enter the plastic envelope around the thin material of the sensor.   Once the liquid is in contact with the sensor material the LLS uses a patented resistive sensing technology to accurately and reliably measure the liquid level in a container.

Included with each LLS sensor is a clip that allows for the mounting of the sensor to the side of the sump, aquarium or container.  Have a Euro braced sump?  Don’t worry you can simply mount the LLS sensor to a baffle inside the sump.

Later in 2022 Neptune Systems will release a magnetic version of this clip and a clip that mounts to a euro-braced sump or aquarium.

Generally the sensors respond to liquid level changes at a rate of about fifteen seconds per inch of water level change.  So if the water level was suddenly decreased three inches, then it could take up to forty-five seconds to reflect this change.  While quick depth level changes are uncommon in an aquarium, and, typically, changes  are reflected more quickly than this, for this reason, it is best practice not to use the LLS for immediate control needs— like auto top-off control.

Once calibrated the LLS is accurate to about two-tenths of an inch.

Liquid Level Sensor- 23″ (LLS-23)

The 23″ sensor is a bit larger version of the 15″ sensor and can be utilized in similar applications to the 15″ but for larger sized-aquariums.   A great application to consider is utilizing these advancing a roller mat.
