Neptune Systems LDK Leak Detection Kit Neptune Systems LDK Leak Detection Kit

Product Code: RNE17015
The Neptune Systems LDK Leak Detection Kit will give you piece of mind. Aquarium leaks are one of the most feared events for even the most seasoned aquarist—and for good reason. When it comes to leaks, it’s not just about whether you’ll have one, but when it happens, will you catch it in time? Most often if you catch a leak in the early stages, when it is a simple drip, you prevent hundreds, if not thousands of dollars in damage.

Neptune Systems FMK Flow Monitoring Kit Neptune Systems FMK Flow Monitoring Kit

Product Code: RNE17295
Measuring the flow of your aquarium’s main return pump is an incredibly useful piece of information. The problem is solved with the Neptune Systems FMK Flow Monitoring Kit (& Apex Controller). The key benefit would be to have the Apex notify you the instant the flow stops for any reason — usually the result of a failed or faulty pump. Furthermore, an indication of a reduced flow rate could be used to determine that the pump or the lines are dirty or are becoming clogged with algae, debris, animals, or the growth of organisms inside your plumbing.

Includes:

  • FMM (Fluid Monitoring Module)
  • 1" Flow Sensor (FS-100)
  • Two 1/2" Flow Sensors (FS-50)
  • Two 1" Unions
  • Two 1/2" Adapters

Neptune Systems FMM Fluid Monitoring Module Neptune Systems FMM Fluid Monitoring Module

Product Code: RNE17185
The Neptune Systems FMM Fluid Monitoring Module is a multi-purpose device that, with the help of various accessories, enables your Apex to monitor water flow, detect water levels and detect leaks.

The FMM has four ports where you can plug in various sensors and accessories (all sold separately). The best part is that they do not need to all be of the same type. This means if you want to have a flow sensor in ports 1 and 2 and then a leak detection probe in ports 3 and 4 – NO PROBLEM! Want a flow sensor for your return pump, an optical sensor for emergency sump level detection, and two leak detection probes, NO PROBLEM! Just plug them in and the FMM will automatically sense which type of sensor you have in each port.
