The old way (still good)
Important reasons to monitor your tanks levels
Peace of Mind: Knowing the levels of fuel, water, and waste tanks at all times gives you the assurance that you have enough supplies for your voyage and reduces the risk of running out at sea.
Safety and Liability: Keeping track of tank levels helps prevent spills or leaks, which can be dangerous to both the crew and the environment. This can also reduce your liability in the case of an accident.
Types of tank level measurement
Side Gauge Tank Level are often fitted on boats. The main disadvantages are that the user need to go to the engine room or the location of the tank and open the control valves to check. It gives the user ball park of the amount of fuel or water available. Recommended addition of NMEA2000.
Analog (Resistive) Tank Level Sensor are often fitted on older boats. Not very accurate and influenced greatly by the splashing of the liquid in the tank. We recommended conversion to NMEA2000 with Six Analog Input Module or upgrade to Ultrasonic tank level sensor
Ultrasonic tank level sensors are modern measurement device that uses ultrasound to send signal to the surface of the liquid and calculate the time it takes the signal to return to the sensor. Our ultrasonic sensors have an advanced long term compensating algorithm to account for changes from liquid slashing in the tank and preserve true readings. Best suitable with tanks that have access to the top. Can be used for Diesel Fuel, Fresh Water, Gray Water or Black Water tanks.
Pressure based tank level sensors: Our pressure based tank level sensor have great accuracy and are atmospheric pressure compensated to avoid the changes in atmospheric pressure from affecting the true readings. Best suited for fuel tanks that have ports piped near the bottom of the tank. Avoid charing the port of the engine supply as the suction of fuel while the engine is running may affect the readings. Same applies to water tanks port that supplies the freshwater pump, while less critical as the water pump is not constantly running and the readings will return to true when the pump is off.
Submersible pressure based tank level sensors: Our pressure based tank level sensor have great accuracy and are atmospheric pressure compensated to avoid the changes in atmospheric pressure from affecting the true readings. These are best suited to tanks that have access to the top. Easy to install and not influenced by pumps running.
