New Energy Times Readers' Investigation of Galantini Measuring Device

Appendix 13 to New Energy Times Report #3

Rok Pernus
The Delta Ohm device (http://www.deltaohm.com/ver2010/uk/st_airQ.php?str=HD37AB1347) used in the Rossi test is suitable strictly for measuring air humidity (vapor in air), not quality (dryness) of steam. Steam quality is defined as the portion of water droplets in vapor. Those are two different concepts in thermodynamics.

I called Delta Ohm, and they confirmed my suspicions. I asked them, "What is the capability of this device to measure steam quality?" Their answer was, “None. It is not suited for steam quality measurement.”

In addition, boiling temperature can easily be offset by higher pressure. The “chimney" on the E-cat, if filled with water, can raise pressure enough to offset the boiling temperature above the measured temperature in the test. You can check this here, for a reference. It is interesting that measured temperature and height of the “chimney” correspond quite well.


Neil Ferguson (e-mail exchange with Delta Ohm)

Dear Sirs,

I have a question regarding the suitability for a particular purpose of one of your instruments, the Delta OHM #HD37AB1347 Indoor Air Quality Monitor. The purpose is to measure accurately the relative quantity of steam to liquid water aerosol in a gaseous exhaust. The exhaust consists exclusively of water or steam — no other gasses or other substances.

I am concerned that, though the instrument may be suitable for measuring the ratio with respect to volume, it isn't quite sensitive enough to measure the ratio with respect to mass. I am concerned about this because of the great difference in specific density between steam and liquid water (1,600X). The gas flow might contain an insignificant amount of liquid by volume, yet by mass the liquid could constitute the great majority of the exhaust's mass. It is that condition that I need to detect. Yet some instruments might not be capable of sensing that case.

Can you tell me whether I am correct in this concern or whether the HD37AB1347 can measure the ratio of specific densities in the exhaust with reasonable accuracy? I'm thinking +/- 10% is more than enough.

Thank you very much for your advice on this question.

Valentina Meneghini responded:

"Thank you for your inquiry.  Actually, we regret to inform you that we do not have any instrument among our production which is suitable for your application. Any further information about our instrument is available on our Web site, where you can also download any data sheet as well as the general catalogue."
