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.

Nice socks.
Comfortable socks: who could ask for anything more? They seem to be of a nice quality, but I buy socks often so there's a rotation going on. A little pricey, but ankle socks always have that sporty look. Fit well, but kind of thin, which isn't a deal breaker.

Best socks on the market
Number of Items: 6, Color: Black/Graphite (6-pairs), Size: Medium
I highly recommend purchasing multiple orders of these socks. I used to wear puma socks that had the padding around the arch and were extremely thick (being that my feet are always cold) i wanted something thick again especially during the winter time. I have had these socks for over two months and I can truly say that they were a better purchase than my pumas. They are so thick that wearing even one pair will still fit into my tennis shoes or running shoes but my toes NEVER get cold. I put a lot of wear and tear on them and they have never started tearing on the bottoms like most socks do. Socks usually develop holes or tears from the friction but I wore the same pair over and over again while walking 13+ miles a day and I cannot tell any sign that these are going out on the bottom. I highly recommend purchasing multiple pairs of these socks.
