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.

Bed pillow
The best pillow for people who have a hard time choosing a pillow. Pricey but worth it. Love the way I can conform it to my liking.

Packaging for shipping = terrible. Pillow = 10 stars
The pillow is great; the shipping/packaging not so much. Normally Amazon warns me if an item is being shipped in manufactures packaging and gives me an option to choose to have it boxed in Amazon packaging; I was not given that warning or option for this item. I am honestly confused why anyone would think shipping a pillow in just its vinyl store packaging “dust” cover would be a good idea. The vinyl cover arrived fully damaged. Cuts from what look like a box cutter, the handle 1/2 torn off, the zipper was 1/2 unzipped… Thankfully the pillow was not damaged or this review would be much different; but honestly who ships a pillow of any price point in a 10mil vinyl dust cover? About the pillow. My young adult child has been using a Bedgear pillow for about 9 years…the same pillow actually. It has stayed in a waterproof pillow cover inside a pillowcase that gets washed weekly, and the pillow has held up great. Recently I noticed the pillow was being used without the 2 covers and had gotten something spilled on it. Since the pillow is spot clean only and the inner foam is not submersible in water I decided it was time for a new pillow. Their original model was the original Summit but since they toss and turn and then end up on their stomach we decided to try the Multi position this time. They have slept on the pillow for 3 nights now and seem extremely happy.

Best one so far
Still on the never ending quest for the perfect pillow. Must say that for the price this one can't be beat. Not willing to invest a small fortune on a pillow and this one is extremely reasonable
