Apollo Ultrasonic Oil Tank Level Monitor/Gauge is the original ultrasonic oil tank contents gauge and comprises a tank mounted transmitter unit and a plug in receiver unit. How the Apollo Ultrasonic Oil Tank Level Monitor Works: Tanks should only be filled to 95% of their brimful capacity. In the event that the tank is filled to the top, this will not harm the transmitter as it is a sealed unit. Apollo Ultrasonic Smart Oil Tank Level Monitor is designed specifically for domestic oil heating installations.

When all ten bars and red light are pulse flashing this indicates that the float switch/sensor has been activated and has detected oil/liquid in the bund area and must be attended to immediately. This signal may also occur if the float switch/sensor has not been correctly installed, see instructions, and is lying horizontally, instead of vertically, or is not hanging freely approx 100mm from the bottom of the tank, therefore, triggering the sensor. The reason for the foregoing is that the Ultrasonics bounces a sound from the surface of the oil/liquid and measures the time it takes to then give a reading but if the oil/liquid is too close then it cannot record a time, it, therefore, needs a distance of 100 – 120 mm to give a correct reading This might open up the possibility to match a transmitter and receiver when the transmitter is already installed in the tank.The annual cost of running the Apollo Smart is approx € 1.63 based on current ESB prices dated 03.10.11. The Apollo Standard/Apollo Ultrasonic Electronic Oil Tank Contents Gauge allows you to measure the level of fuel in your tank from the warmth, comfort and convenience of your home. Not suitable for underground tanks. How it works The information here is just to help would be DIY fixers. I take no responsibility for anything you do. If you work on this board with the mains power on be careful of the big resistor and surface mount resistor in the top right corner of the board they have 240 volts A/C on them.

I have soldered two wires onto the inputs to the bridge rectifier and on my PCB it reads 5.0 volts A/C. I think this needs to be about 8 volts A/C for the unit to work correctly. The transmitter is closed in a weatherproof plastic casing that protects it from the elements and UV light. It remains more reliable than other brands. Home heating oil users can ascertain the volume of fuel remaining in their tank, and monitor heating costs, consumption and emissions too.

Specification

When the Apollo Smart has been unplugged and is plugged in again, it will start up in ‘Lrn’ mode. Simply press any key to exit.

Every Apollo Ultrasonic Tank Level Monitor is supplied complete with long life lithium battery, full instructions and immediate fittings as standard. The DC output from the rectifier goes to pin 8 of a 78L05A 5 volt regulator chip. I have a white wire soldered there and my PCB reads 3.68 volts there. I think this needs to be about 7 volts D/C for the unit to work correctly. If the tank is filled to the top as described then the oil/liquid will be too close to the underside of the transmitter and will result in intermittent incorrect readings or Errors until the oil/liquid level drops to 100 – 120 mm from the top of the tank. The readings will then return to normal without any adjustments or action needed. Please note depending on oil usage this may take a couple of weeks.The reason for the foregoing is that the Ultrasonics bounces a sound from the surface of the oil/liquid and measures the time it takes to then give a reading but if the oil/liquid is too close then it cannot record a time, it, therefore, needs a distance of 100 – 120 mm to give a correct. The integrated oil tank alarm sounds when the oil level reaches a low status to alert the user that they need a fuel delivery, as well as sounding if the tank contents drop suddenly indicating a potential theft.

No, your transmitter will continue to work correctly. However, it would be recommended to clean it and refit the device. The transmitters are weatherproof and will remain fully operational. Tank mounted ultrasonic transmitter unit, compatible with the standard 20mm port fitted to modern plastic oil storage tanks (please ensure adequate space on tank to mount transmitter) The reason for the foregoing is that the Ultrasonics bounces a sound from the surface of the oil/liquid and measures the time it takes to then give a reading but if the oil/liquid is too close then it cannot record a time, it, therefore, needs a distance of 100 – 120 mm to give a correct reading. Q2. I have lost the instructions how do I rematch the unit and how do I know what Pin settings to set on the rear of the receiver plug.
