Safiery STAR-Tank Radar Bluetooth Sensors STAR-Tank sensor support is added to Venus OS. These radar tank level sensors use Bluetooth Low Energy. This wireless technology allows devices to be networked within a range of about 40 meters (with Bluetooth Adapter added to Cerbo GX, see below), while consuming significantly less power than ordinary Bluetooth technology. The expected battery life is 5 years with tank measurement averaging 50%. Battery life is less at around 3 years if tanks average 10% level for example. The liquid level, temperature and sensor battery voltage are streamed wirelessly to the GX device. STAR-Tank sensors feature phased coherent radar sensing for non-pressurized tanks. The tank level range is 2m as standard. This can be extended, consult Safiery. The top 30mm from the base of the sensor is a dead band. If the tank is 12mm thick fiberglass, then the deadband is 18mm below the top of the tank. The sensors are attached directly on top of any non-metal tank including thick fibreglass tanks. For metal tanks, the sensor needs a clear view of the liquid. To achieve that, a 5 hole SAE pattern adapter is included into the base. To achieve an air tight seal, use “gas sealing tape” (generally pink) and wrap on the thread and screw into the base plate. This prevents gas from the tank passing through STAR-Tank. For non-metal tanks, adhere the base plate. Then, screw the STAR-Tank module onto the base. STAR-Tank suits black water tanks, even with foam above the liquid line.

STAR-Tank has several machine learning functions for caibration using AI.

1. There are hundreds of reflected radar signals from the bottom and side of the tank. Our program selects the dominant value during the first 10 seconds of “setup” mode. It then retains the profile for your tank at the tank depth selected. Every time a different tank depth is selected using the setup mode, a different filtering profile is stored in memory. 2. The shape of these reflected signals changes with tank depth. By going through the setup process and nominating the tank depth changes the way we filter the reflected signals and select a dominant value. 3. The “Setup Mode” process described on the next page combines 1 and 2 above into a single process.

Safiery STAR-Tank Radar Operating Modes and Calibration There are 4 Operating Modes for STAR-Tank: 1. Hibernation Mode (commonly called “off”) 2. Setup Mode (used to calibrate/setup and reports at 10 sec intervals for 10 mins) 3. Normal Mode with 60 second scan time automatically occurs 10minutes after being in setup mode. 4. Over the Air Update Mode (commonly call OTA) is a separate user initiated mode. Before moving from Hibernation mode to Setup mode, there are two allowable positions for STAR-Tank in SETUP Mode. Either: • Start with an empty tank or one containing a minimal amount of liquid and have STAR-Tank in its recording position. OR • If the tank is not empty, point the STAR-Tank sensor into open air, ensuring there are no obstructions within at least 5 meters and follow the Setup mode with STAR-Tank pointing into open space. Do not proceed with the calibration on a partially full tank with STAR-Tank on top of the tank. After following Setup Mode below, then place STAR-Tank on a partially full tank. THEN Enter Setup Mode: 1. Press and hold the button for 5 to 15 seconds, then release to enter SETUP MODE. The LED will indicate the following statuses: • Green: Button held for less than 5 seconds (not in Setup Mode). • Fast Flashing Red: Button held for 5 to 15 seconds (Setup Mode activated). • Then Release the button before the 15secs is up. The LED will now show the selected maximum tank depth as follows: • One Green Flash for 1 sec: Small Depth of 0-50cm. To change the depth, go back to step 1 above and repeat the 5 to 15sec press. Remember to release the button before 15 seconds. The calibrated tank depth will cycle through the three levels. Once the level is nominated, the AI function is now complete. Every 10 seconds for 10 minutes, the LED flashes tank level status: Flashing purple means tank is absolutely full or some object under sensor is blocking it like a baffle or the tank is empty and DRY. Flashing red means the tank is close to full. Flashing green means tank level is 100cm or more below the sensor. In-between are the colours of orange to yellow. • Two Red Flashes for 2 secs: Medium Depth of 50-100cm. • Three Blue Flashes for 3 secs: Large Depth of 100-200cm.

Safiery STAR-Tank Sampling Rate and Approvals To turn STAR-Tank off, press and hold the black button. The sensor will not use any battery capacity when turned off. . The normal sampling interval for the long battery life is 60 seconds. Pressing the black button for 1-2 seconds will change the sampling time to 10 seconds for up to 10 minutes. Then the sampling reverts to 60 seconds. Many tank level sensors use averaging to smooth out signal results. We cannot do this with STAR-Tank as it would consume too much battery power. Every reading is a one shot result. The implications of this is that occasionally, you may see a flickering of value for 1 cycle.

In future developments on the Victron side, the temperature value may be used to trigger the temperature relay function on the GX device with relays to initiate stirrers or heaters in tanks as well as notification of this.

To connect STAR-Tank sensors to the GX device via Bluetooth, the GX device needs Bluetooth functionality. Although GX products already have built-in Bluetooth, this internal function may be disabled if the processor gets too hot. Safiery recommends installing a Nano USB Bluetooth adapter from the list below.

This radar tank level sensor is approved with FCC for USA. It is compliant with European commission radio equipment directive 2014/53/EU article 3.1 and 3.2. and is CE and UKCA approved.

Safiery STAR-Tank Radar Sensor Positions and Calibrated Depth

STAR-Tank uses reflected radio waves at 60GHz. It is therefore important that the sensor is away from the edge of the tank and free from baffles. The test setup above is a nominal 40L tank with 25L of water in it. The Centre Test Sensor is reading correctly as the range for the bottom of the tank is set correctly at 35.6 cm in this example. 1 Test Sensor 5 was calibrated at same bottom reading then lifted up to the raised side section of the tank which is 9 mm higher. This meant the distance to the water inside was 9 mm longer. At 40L for 356mm depth, the volume per mm is approx 0.1124 L. So raising 9 mm will reduce the aparent volume by 9 x 0.1124 = 1.011 L. 2 Test Sensors 2 and 10 are too close to the edge. The Frenzel lens is set to give a 30 degree cone of trasmission. The side is interferring with this giving a 100% reading for Sensor 10 and 94% for Sensor 2 which is a little further from the edge.. 3 If the tank is a shallow tank of say 200-250mm depth, the standard STAR-Tank sensor will show fluctuations when full as the top dead band is a percentage of full scale setting. For a nominal 1m calibrated sensor: the top deadband is about 50mm. The sensor is 16mm above the bottom of the housing leaving 34mm below top of tank. Generally, full tank accuracy is not important. But if this irritates you, then set the tank level in the Cerbo to Full at a value greater than 0. Here is a guide.

20~50 cm Depth

50~100 cm Depth

100~ 200cm Depth Dead band 50-70mm When tank is full. But won’t read past 2,000mm

Dead band 9-15mm When tank is full. But won’t read past 500mm

Dead band 30-35mm When tank is full. But won’t read past 1,000mm

STAR-Tank uses Phased Coherent Radar In Phased Coherent Radar, a series of short-duration radio frequency pulses are transmitted towards the water line from above. These pulses are reflected back and received by the radar system's antenna. The received signals are then processed and analyzed to determine the depth. The term "coherent" refers to the radar system's ability to maintain a constant phase relationship between the transmitted and received signals. This coherence allows for more accurate measurements and improved signal processing techniques, such as coherent integration, which enhances the radar's sensitivity and range resolution.

Functionality of STARSHIP - What it does

Devices connected in a marine world have defined protocols such as NMEA 2000 for wired connectivity. However, for non-essential, comfort and convenience devices like lighting, air-conditioning, fans, and appliances there is now a connectivity alternative with wireless digital switching. This alternative Wireless connectivity can be in parallel with the wired system. STARSHIP offers two layers of wireless communication, both with Open Protocols as well as preserving NMEA 2000. More and more devices and appliances have inbuilt wireless connectivity, because more advanced functions can be selected using wireless connectivity to purposeful Apps. However, it isn’t practical nor customer focused to require a collection of Apps to fully operate these devices. So sometime in 2019, Apple, Google, Amazon, and Samsung agreed to commit to a common standard for IOT devices and appliances that any of their platforms would connect with using one native app on the smartphone or tablet. The Standard was published in December 2022 and is called “Matter”. Matter is a published open protocol with IPv6 endpoints. Once provisioned, it does not require the internet. It has a high encrypted security feature and uses conventional WiFi and/or ethernet between devices. STARSHIP is compliant with Matter but with a significant difference: It also has integration of both Wired NMEA2000 and Long Range Bluetooth (uses 802.15.4 transport layer). This means a light can be turned on and colour changed from an MFD display then turned off or the colour changed using wireless STAR-Switches in a cabin. However, the really important functionality is the automation. Apart from convenience of one “Home Control” app for multiple devices (currently over 2,000), there is the Energy Management Automation that is particularly useful. Matter includes this as well as battery monitoring such that load shedding of devices can be done when energy needs to be conserved. Simply departing a boat can trigger automation that turns off all non-essential devices. STARSHIP is the only DC powered Matter compliant device available. Layer on to that the 2 other communication methods. We envision a future where most appliances and lighting will be available under the WiFi standard protocol.

The clever part by Safiery was integrating CAN/NMEA functionality and long-range Bluetooth devices into one system. Simplified Interoperability with any Smartphone’s Native Home Control The Bluetooth connectivity uses the new long-range 802.15.4 transport layer. Results are 100m range line of sight and 40m through metal skins. This is used for the wireless physical switches and the Radar Tank Monitoring. They operate independently of the other communication methods with high encrypted security. They are battery operated with a minimum of 4 year life.

Combines Old with the New Wired and Wireless to Reduce Cost

The user benefit of this architecture: a system can be completely delivered with NMEA & wireless switching. When the user wishes to add automation, Smartphone App control or remote cloud monitoring, they simply install Matter as an overlay network. The user can redefine switch modes, and scene automation without programming by others. This enhances utility at reduced overall cost. The commercial benefit to the boat builder is a significant reduction in installation complexity: Installation time, cabling cost and weight, commissioning time and troubleshooting time are all at an absolute minimum. Simplicity of use allows for end user changes at minimum cost.

FAQ on Support

1. Signal is showing 100% and LED is purple. If install on top of tank without penetration, ensure tank is NOT metal nor has a metal liner. Ensure it is not positioned above a baffle. Move the sensor and try again. Ensure sensor is at least 200mm in from vertical edge. 2. Sensor shows it is reading but Cerbo can’t detect. Ensure there is a Nano Bluetooth receiver in the USB receiver on the Cerbo. This must be the 2nd or 3rd slot away from the HDMI cable as the first one is reserved for power only to the Touch Screen. 3. Reading is showing full or empty when it is neither. Adjust the minimum and maximum level values in the Cerbo setup display. On the setup display you will read the tank depth “actual value’ in cm. The Min and max values must be either side of that value. 4. How do I calibrate accurately? If the tank is a regular shape, start with it empty and press button for the initialization described in this manual. Then fill the tank to 95% and check the full value limit. There is a 30mm deadband from the bottom of the sensor. When the liquid is within this zone, it will read 100% full. © Copyright Safiery Pty Ltd 2024
