How to Replace a Mini SureSite Transmitter  


The below information will help explain how to replace a transmitter on a Gems Mini SureSite visual level indicator.  Only proceed to this step if you’ve determined the transmitter is faulty by going through the troubleshooting steps.  One important thing to remember is that the transmitter must be located 180 degrees (opposite side) of the Flag Assembly.  This ensures the transmitter is in the correct orientation to receive the magnetism from the float.  If it is not within this orientation the reed switches within the transmitter may not close.  See the below image for further detail. 


First step is to identify what type of transmitter you have.  Luckily there are only two that work with the Mini Suresite, and the only difference between them is the location of the junction box.  P/N 804605-XXX (XXX is indicating length in inches) will have the junction box at the bottom.  P/N 808940-XXX will have the junction box at the top of the SureSite.  804605 is the more common configuration.  See the below images detailing both.   


Next step is to measure between the red and blue indicating tapes on your transmitter.  The blue indicates the bottom portion of the indicating level, and the red marks where the indication level stops.  The distance between these two marks in inches will dictate how long we make the transmitter and the complete p/n.  For example, if your measurement is 36”, with the junction box at the bottom, the p/n will be 804605-036.  If your junction box was at the top, your p/n would be 808940-036. ‘X’ shows the indication length below. 


Once you have determined your p/n please contact Gems for pricing and availability.
