Abstract
Energy transmitted to a load in a fluid medium is measured utilizing a probe having an elongate heat transmitter that includes a sensing tip at one end, a heat exchanger at its opposite end, a thermal impedance forming at least a segment of the heat transmitter, and temperature sensors spaced apart along the impedance. The temperature of the sensing tip is maintained different from that of the sensed fluid. A read-out is responsive to the temperature sensors and it is calibrated in terms of the energy content of the fluid flowing in the sensed passage. Corrections for various factors of error are incorporated in the read-out. A relative simple yet reasonably accurate measure is made of the energy in steam, where the heat exchanger of the probe is a passive heat dissipator. By controlling the heat exchanger so as to maintain the sensing tip at the temperature of the fluid in a reference condition, measurement of the energy content of the fluid in another condition is made, this being applicable not only to steam systems but also to forced air heating and cooling systems as well as circulating liquid heating and cooling systems.
