Abstract: A flow-sensing system is provided which employs a pair of sensing resistors. One of the resistors is disposed within flowing fluid, while the other is shielded from the flow. The sensor resistances are held constant by identical feedback circuits which maintain the relationship between current values in the sensors for this purpose. The required difference in currents in the two resistors enables fluid flow to be computed.Input and output temperature sensors are provided to enable temperature difference to be measured and combined with fluid-flow to indicate the rates of BTU flow. One temperature sensor and the fluid-flow sensors constitute an assembly miniaturized in a solid state chip.

Abstract: The meter forms part of a heating system supplied with thermal energy in the form of hot water from a heat generator, and serves to determine the amount of heat supplied to a consumer, for the purpose of appropriately charging the consumer for incurred heating costs. The meter includes a computer, operating on the analog principle, a volumeter and connection elements for connection to signal processing devices. The volumeter is formed by a first tubular body through which the hot water flows to the consumer, and this first tubular body is surrounded coaxially, at a definite radial spacing therefrom, by a second tubular body so that the two tubular bodies define a completely closed annular space. The cooled hot water returns through a return line. The supplied hot water in the first tubular body constitutes a primary medium flowing therethrough, and the completely closed annular space receives a secondary medium which is heated by the primary medium. A temperature sensor and a pressure head probe are operatively connected to the first tubular body, a second temperature sensor is operatively connected to the return line, and electronic elements convert the pressure head into an electrical quantity proportional to the volume of the primary medium flowing through the first tubular body. The temperature sensors serve to determine the heat amount. A thermogenerator is connected in communication with the completely closed annular space, for generation of electric energy by the heat of the secondary medium, and an electronic transformer is connected to the thermogenerator to convert the generated electric energy into operating potentials applied to the computer and to the volumeter.

Abstract: In the hot water heating system disclosed herein, a sensing means such as a thermistor provides a first electrical control signal which represents deviation of outlet water temperature from preselected value and a flowmeter provides a pulsating electrical signal having a frequency which varies as a function of rate of flow through the heating system. An output signal is generated having a frequency equal to that of the pulsating signal and a squarewave pulse duration which varies as a function of the first control signal. Heater means are then energized by the output signal so as to provide a thermal input to the heating system which is substantially proportional to the product of water output temperature deviation and flow rate. This control minimizes output temperature fluctuations due to thermal inertia and heater lag.

Abstract: A method and apparatus for measuring the flow velocity of a flowing fluid includes a positive temperature coefficient thermistor to be immersing within the flowing fluid in order to provide a measurement of the rate of heat dissipation of the thermistor produced by the flowing fluid, and thereby a measurement the flow velocity of the fluid. The positive temperature coefficient thermistor used has a resistance which increases sharply at the predetermined temperature at which electrical current is maintained in the thermistor such that the thermistor is self-controlled to maintain substantially the predetermined temperature, whereby the electrical current drawn by the thermistor is a measurement of the thermal load on the thermistor resulting from the thermal heat dissipation therefrom by the flowing fluid, and thereby a measurement of the flow velocity of the fluid. Various embodiments of the invention are described, including those for measuring heat flow in a centralized heating or air conditioning system, wind velocity and direction, and flow velocity in a wind tunnel.
