Works beautifully.

November

Downloaded the Maretron N2K Analyzer version  2.2.2.1
December  Upgraded software versions of the varios sensors and modules, except for the DSM150 that has to be upgraded by Maretron.  Got into trouble since after upgrade the analyzer tried to access two different USB ports with following crash.  Maretron very good with support. Service manager program must be 4.x, not 3.6.

January

Almost finished the two bilge RIM connections to the sensors.  Bow bilge alarm not connected.
February Installed new Maretron DSM 150-2 Display

 

 

Equipment

Maretron Net Middle Panel

 Maretron net middle  

Located in the middle, below the bridge. 

This is where the Maretron net gets its power that comes from the dedicated circuit breaker located in the starboard DC power hull panel.

The USB 100 NMEA 2000-USB gateway is connected here.


Maretron DSM 150-2 Display

The Maretron DSM 150-2 is a 3.5 inch high bright color display for NMEA 2000 network.

This display is self standing.  The Maretron USB 100 USB Gateway is NOT needed to access the network.

Special procedure to upgrade the software.  Danger to loose all the data! 

Purchased first in March 2013, second February 2016.

Maretron TLM 100 Level Meters

The Maretron TLM 100 level meter senses levels of liquid tanks using ultrasonic technology and transmits the liquid level to the NMEA 2000 network.

Two level meters are used to measure the water tanks, two the fuel tanks and one the waste waters tank.

The minimum depth that can be measured by the level meter is 5.08 cm  (2").

Purchased March 2011. 

Measuring Fuel Quantity

2 Maretron TLM level meter
for the fuel tanks
Serial no 1501352
Serial no 1501324
Mfg model version  1.0

The level meters measure the fuel quantity in each tank by measuring the distance between the sensor 60 mm above the underside of the top of the tank and the fuel surface.

The fuel capacity of each tank is 3,241 liters or 857 US gallons.

To correctly measure the fuel quantity in this odd shaped tank the meters must be equipped with the focus tubes.

fuel tank levels

The above picture shows the shape of the fuel tank, up to the maximum fuel level.  The level meter is located 60 mm above the maximum fuel level, the top of the tank.
At the maximum fuel level the wetted side of the tank has a surface of 1.304 m^2.  With the fuel level 100 mm lower, the wetted side has a surface of 1.191 m^2 and so on until the level of the fuel is 100 cm below the maximum fuel level, then the wetted side has a surface of 0.217 m^2.  Fuel levels below are not considered.

The fuel quantity in liters is calculated by multiplying the wetted tank area surface in m^2 with the length of the tank in m  which is 2.485 m. 
The distance between the bottom of the tank to the top of the tank is 1.312m.  For Americans remember that 1m^3 (1 cubic meter) has a volume of 1000 liters.

Measuring Water Quantity

Maretron TLM level meter
for the water tanks
Serial no 1500812
Serial no 1500828
Mfg model version  1.0

The level meters measure the water quantity in each tank by measuring the distance between the sensor 60 mm above the underside of the top of the tank and the water surface.

The water capacity of each tank is 649 liters or 171 US gallons.

water tank level

The above picture shows the shape of the water tank, up to the maximum water level.  The level meter is located 60 mm above the maximum water level, the top of the tank.
At the maximum water level the wetted side of the tank has a surface of 0.654 m^2.  With the fuel level 100 mm lower, the wetted side has a surface of 0.545 m^2 and so on until the level of the fuel is 60 cm below the maximum fuel level, then the wetted side has a surface of 0.058 m^2.  Fuel levels below are not considered.

The water quantity in liters is calculated by multiplying the wetted tank area surface in m^2 with the length of the tank in m  which is 0.995 m. 
The distance between the bottom of the tank to the top of the tank is 0.721 m.  For Americans remember that 1m^3 (1 cubic meter) has a volume of 1000 liters.

Measuring Black Water Quantity

1 Maretron TLM level meter
for the black water tank with focus tube
Serial no 1501985 Mfg model version  1.0

The level meter measures the waste water quantity in the tank by measuring the distance between the sensor 10 mm above the underside of the top of the tank and the waste water surface.  The sensor is equipped with a focus tube.

The holding tank has a capacity of 170 l or 22 US gallons, is 110 cm long, 44 cm wide and 40 cm high.

 waste tank level

The above picture shows the shape of the fuel tank (a rectangle), up to the maximum waste water level.  The level meter is located 10 mm above the maximum waste water level, the top of the tank.
At the maximum waste water level the wetted side of the tank has a surface of 0.176 m^2.  With the fuel level 40 mm lower, the wetted side has a surface of 0.158 m^2 and so on until the level of the fuel is 400 mm below the maximum fuel level, then the wetted side has a surface of 0 m^2, an empty tank.

The waste water quantity in liters is calculated by multiplying the wetted tank area surface in m^2 with the length of the tank in m  which is 1.10 m. 
The distance between the bottom of the tank to the top of the tank is 0.40 m.  The width of the tank is 0.44 m.  For Americans remember that 1m^3 (1 cubic meter) has a volume of 1000 liters.
The following calculations are approximate since the the wall thickness and the bulging of the tank are not considered and a considerable safety factor has been built in.  You don't want to overflow and pressurize the tank.

Aqualarm Float Switches

The Aqualarm float switches (high water bilge alarms) trigger a current when the bilge water level reaches a certain level

There are  currently 4 Aqualarm float switches on each side that monitor the bilge water level at the following points:

Forward compartment (not installed)
Middle compartment
Engine room compartment
Engine room entrance compartment
Steering compartment

Each side of Aqualarm float switches receives power from the dedicated bilge circuit breaker located in the port and starboard DC power panel above the fuel tanks.

See also the Aqualarm float switches in the Bilge Pumps section of this manual.

The Aqualarm float switches  are connected with a gray 4 wires cable to the Maretron RIM switch indicator modules with the following color codes:

Aqualarm cable Gray cable Gray cable 2  
Brown Brown Brown Signal - High water alarm
Black White Black Negative
Red Green Gray 12 V positive

Before starting the server make sure that the network is connected to a USB port on your computer and that the USB Maretron dongel is inserted.  How primitive to still use a dongel.

The only annoyance is that when running the N2K Analizer to change to the N2K View the computer has to be restarted.  At least I found no other way way to switch programs.
