New Flow Calorimeter for Multi-Wire Test

We're happy to announce that we have a new tool in our quest for making precise, economical, and understandable experiments. HUG has engineered up a water flow calorimeter intended to be used with the small, LENR-stick type test cells. We will use this new calorimeter when we load many types of celani waire into one test cell in the coming days and weeks.

The calorimeter is detailed here: Water Flow Calorimeter Description  (Entire document embedded below, also)

The next step is for us to perform a careful calibration of the instrument with the empty Multi-Wire LENR-Stick.  This should be accomplished with the week.  

The data for this apparatus is not streaming, yet, but will be after calibration.  If anyone has a reliable, relatively new laptop that they would like to donate, we could use one that we could assign exclusively to this apparatus.

View of the data acquisition and control boards.  They are mounted to the foam, but not enclosed, since they generate heat and would change their own temperature a lot if insulated.

Another view of the thermal isolation plate

Top thermal plate of the calorimeter - temperature controlled water from the reservoir is pumped through a heat exchanger block mounted between rwo aluminum plates to help isolate the calorimeter beneath it from ambient temperature swings. Ambient isolation is key to making precice calorimetry, especially when you are measureing temperature rise to the milli-Kelvin.

Solid state heat pump - made from a thermo-electric assembly we had lying around, this can pump at least 200 watts out of the water reservoir. That is enough to handle at least a half dozen calorimeters simultaneously.

Water flow lines feeding the bottom plate, the top plate, and two lines to the core calorimeter. Note the precision flow adjuster valve that sets the rough flow range to the calorimeter.

This is the thermistor and heater fittings. The orange/orange/white pair of wires goes to the thermistor. The other fitting is one of the heaters.
