This quick tutorial will guide you through the steps on installing the Rocket Wireless Fuel Level Monitor.
Begin by determining the total tank height either by making a direct measurement or using the DIP Switch Settings chart at the end of this post.
Once the tank height is determined, use the DIP Switch Settings chart at the end of this post to locate the correct DIP switch setting for your tank. The row of DIP switches is located on the back of the Receiver Display. Toggling an individual switch up towards the antenna will put it into the “ON” position.
Install the supplied metal adapter into an unused 2″ NPT opening in the top of the tank. Apply pipe sealant on the Adapter threads and tighten appropriately. Do not install the transmitter at this time.
On the Receiver and Transmitter there are black dots located on the side of each device. To synchronize, plug the Receiver Display into a convenient 120 VAC electrical outlet.
The LCD display on the Receiver will show a flashing top bar (for about 2 minutes)
During this 2 minute “Learn” period, slide the Transmitter, starting at the bottom of the right side of the Receiver until the black dots touch each other or until the Receiver Display bars begin to increase in size
The Transmitter stays in “Fast” transmit mode for 10 minutes following synchronization. Moving the Transmitter up and down above a solid surface should decrease or increase the number of bars respectively on the Receiver Display. If you wish to deactivate “Fast” transmit mode, again slide the Transmitter dot towards or past the Receiver dot.
Now fasten the Transmitter to the Adapter using the gasket and screws provided. Do not over tighten.
The Rocket 17000 system uses ultrasonic radio wave technology to measure the fuel level in the tank. It then uses wireless transmission to send the measured fuel level to the Receiver

I put the Rocket on the tank and plugged in the receiver but it doesn’t work.
Customer does not wait long enough for the signal to be sent.
After plugging the receiver into a wall outlet and waiting for the 2 minute learn time to expire, you may need to wait another 8 minutes before the Rocket transmits to send a measurement to the Receiver. If the Receiver does not show a level (some number of bars) shortly after the 10 min period, the go through a re-synchronization process.
The number of bars on the receiver is not correct when compared with a mechanical gauge on the tank.
Receiver DIP switch settings are inconsistent with actual tank height.

I cannot synchronize the Rocket to the receiver.
(A) Receiver is not in Learn Mode – Unplug receiver and plug back in and verify that the top bar is blinking. Now proceed with the Sync Process.
(B) Rocket is in Fast Mode – Bring the Rocket to your ear and listen for rapid “clicking”. If you hear that clicking, pass a magnet across the black dot on the rocket to turn the rocket Fast Mode off. Listen again to verify that the clicking has stopped.
(C) Rocket Battery is dead – Rocket has an approximate 10-year battery life, so this is usually not the problem. Install new battery per instructions on Page 2. Make sure that the Warranty label (torn when rocket is taken apart) is matched up after assembly. The top and bottom plastic housings are “keyed” and must be reassembled properly.
D) Rocket was disassembled and improperly reassembled – Is the battery installed upside down? Were the two housing sections assembled incorrectly (180° off) – which locates the black dot on the other side of the circuit board from where the activation (Reed) switch is located?
I ran out of fuel and the Receiver still said I had oil.
Incorrect DIP Switch Settings on the Receiver
Display contains flashing triangle — no bars displayed
Indicates that the receiver has not received a signal for two hours. Possible causes are:
Display contains flashing triangle — middle bar displayed
Indicates that the Transmitter is not receiving an echo from its ultrasonic signal inside the tank. Likely cause:
CORRECT!
Do not insert a tube or any other sharp or rough edge inside or on top of tank
Do not insert a tube or any other sharp or rough edge inside or on top of tank
Obstacles can block ultrasonic signal
Mount sensor as vertical as possible
