LENR Calorimeter Characteristics

This post will grow over time as more tests are performed on the operating characteristics of the new joule heating based calorimetry system. If there are any suggestions about tests you would like to see with the system, please make them here. This post will essentially serve as a general appendix for future studies utilizing the calorimetry system.
Test 1. Electricity Meter and Light Bulb Ratings (5/20/15)
In order to not take for granted that the electricity meter measures correctly, a test was performed to provide some verification that it is accurate and works as expected. A lamp with 3 light bulbs was used as a test load. Additionally, a home energy monitor (outlet-based) was used as an additional comparison.
EKM Metering Omnimeter Pulse v.4
Generic outlet-based energy monitor (purchased from Ebay)
Lamp with 3 incandescent light bulbs with individual switches (100W, 60W, and 75W bulbs)
Manually collected measurements from the outlet monitor were collected and compared to the digitally collected meter data. The Omnimeter was drawing a small amount of power from the outlet monitor (.6 to .7W) with no load in the system.
Test 2. Comparison between water inlet and outlet temperature readings (5/20/15)
Because the inlet and outlet temperature values will be compared to generate the measure of output power, the temperature readings without the system running were compared for systematic differences between the two sensors. The results indicated that the sensors systematically differed by 1.524C. The Arduino code was modified to add .762C to one probe and subtract .762C from the other. Subsequently, a run of 8 hours of data was collected comparing the corrected sensor data over that time period.
Atlas Scientific Temperature Probes (x2)
There was a high degree of correspondence in the temperature readings between the two probes over the 8 hour period. The average difference between the two probes temperatures over the 8 hour period was .004. The temperature values were logged each second over that time period.
Test 3. Flow Meter Comparison (6/10/15)
The EKM Metering water meter was compared to the inexpensive water flow sensor (YF-S401). The EKM Metering device produces an electrical pulse every 2.83 liters. It is measured by the Omnimeter v.4 and monitored with the EKM Dash software. The YF-S401 data was collected via an IOIO board connected to an Android device. The digital pulse frequency was measured every second and the amount of water flow was totaled. Over a 38 minute test, the EKM Metering device measured 19.82 liters of water versus 19.77 liters with the YF-S401. The difference between the two measures was .3%.
Test 4. Near Tube Surface Temp vs. Internal Tube Temperature (6/10/15)
The external thermocouple is not directly attached to the outside of the cell in this case. There is no use in damaging more thermocouples, since the exact surface temp is not needed for control. Instead, the thermocouple is passed through into the heat exchanger to a position near the surface of the reaction tube. It may more accurately be consider a measure of air temperature within the heat exchanger. The chart below includes both the heat-up and cool-down sequences. It suggests that internal heat exchanger temperatures between 650 and 700 will bring the internal temperature into the Rossi/Parkhomov zone for an enhanced reaction. It was not considered necessary to bring the temperatures completely up to that level since it may have lead to destruction of sensors and resistance wire (in addition to the linear relationship between the temperatures as can been seen in the chart).
