picture of the other end of the copper bulb?
it is a capilary type of gauge normaly you would take a hose off push the copper bulb into the pipe and put the hose back on tight
the water flows over the bulb expanding the liquid inside moving the nedle
there is no wiring only the ilumination but that looks to be missing
