Battery powered method to measure water temp w/LCD display

We need designed and specified a method to measure the temperature of running water in a plastic pipe about .5"dia. The sensor would be inserted into the pipe and wiring coming out of a sealed hole. The accuracy should be within two degrees. We need to display the temperature on a small simple LCD display that is positioned within a few inches of the water. The circuit must be battery powered by a small over the shelf battery,The unit will be operated a for about one hour everyday. We would like the battery to last atleast one year. The temperature range is from 35F to 120F. I will design the mechanical aspects and ensure the LCD and other components will be water proof. I just need the circuit designed and prototyped.
