I was doing a test mash yesterday with water to verify my setup of the Blichmann RIMS Rocket. I routed hoses as follows:
mash tun -> RipTide Pump -> RIMS Rocket (bottom input) -> sparge arm
At the top of the RIMS Rocket I had a Tee fitting with the tee mounted as shown in the RIMS Rocket manual: The flow outlet was out the side of the T and the temp probe (PT100) vertically in the top. The probe was connected to a PID controller with an SSR controlling the RIMS Rocket heater.
I've used this probe/PID setup for other purposes and it has always worked well.
With this configuration, the probe was registering temperature fluctuations all over the place. The PID kept firing the heater as expected but was not able to lock in a stable temperature at all -- it just kept bouncing all over the place with values steadily rising towards my set point.
When not mounted in the tee, the probe reads a very steady temperature as expected.
I tried different flow rates but had no success. It was almost if the probe wasn't maintaining good contact with the water even though the tip was present in the opening of the tee.
Any suggestions?
