    摘要： An integrating flow calorimeter for measuring and indicating the cumulative heat exchanged between a load equipment and a heat-conveying liquid circulating therethrough.A flow measuring device continuously measures the quantity of liquid circulated through the load equipment, and closes a switch for a predetermined fixed interval of time each time a predetermined quantity of the liquid has been supplied to the load equipment. The switch connects a differential temperature measuring device to an electrical power source, which can be a battery mounted integral with the meter.The differential temperature measuring device includes temperature sensors which sense the temperatures of the liquid supplied to, and exhausted from the load equipment. During the time the differential temperature measuring device is energized, the difference between the supply and exhaust liquid temperatures is converted into a pulsed output signal, in which the frequency of the pulses is directly proportional to the sensed differential temperature of the liquid.The pulsed output signals are transmitted to a counting device, which counts the number of pulses therein, and operates an indicating register which indicates the total quantity of heat supplied to the load equipment.The meter can also include a regulating device for adjusting the fixed time interval during which the switch is closed, to thereby compensate for manufacturing error in the flow measuring device.Also, the temperature sensors can be p-n juncture semiconductor devices, which are easily installed in existing liquid lines.

    摘要： Device for counting heat or cold units carried by a fluid and dissipated in a circuit passing through a heating or temperatureconditioning installation and comprising a fluid output meter. This device comprises an electric current meter, the inductor of which is energized by thermoelectric probe resistances immersed in the fluid at the inlet and outlet ends of the installation. The inductor of this electric current meter is energized only when a member adapted to deliver a current pulse each time the fluid output meter has performed a predetermined number of revolutions. The number of revolutions performed by the electric current meter is the product of its time of operation by the temperature difference between the thermoelectric probes.

    摘要： A measuring arrangement comprising a heat meter having a flow sensor, a first temperature sensor, a second temperature sensor and computing means. The first temperature sensor serves to register a temperature in the feed line of the heat exchanger and the second temperature sensor serves to register a temperature in the drain line of the heat exchanger. The computing means serves to calculate the amount of heat exchanged. A first transfer function, which serves to determine the temperature in the feed line based on a measurement signal of the first temperature sensor, is stored in the computing means; a second transfer function is stored in the computing means; wherein the first transfer function differs from the second transfer function; and the second transfer function serves to determine the temperature in the drain line based on a measurement signal of the second temperature sensor.

    摘要： An improved method and apparatus for setting a trip-point temperature value for detection of an over-temperature condition in a chip when a reading from a main temperature sensor exceeds the trip-point temperature value. In one embodiment, the trip-point temperature value is set to a known temperature limit value offset by a temperature difference, ΔT. ΔT is calculated by taking the difference between a reading of the main temperature sensor and a reading of another temperature sensor, remote from the main temperature sensor, while a heat-generating circuit is enabled. The main temperature sensor is distal from heat-generating circuit on the chip and the remote temperature sensor is proximate the heat-generating circuit. For multiple heat-generating circuits on the chip, a ΔT is determined for each of the heat-generating circuits, and the largest ΔT is used to calculate the trip-point temperature value. Advantageously, the largest ΔT determination may be done only once.

    摘要： A signal processing circuit comprises a difference amplifier receiving an input signal and a feedback signal. A bistable circuit switches repeatedly between states only when the difference amplifier''s output is non-zero and positive. The feedback signal is developed by a switch that is closed to apply to an integrator a reference signal in response to pulses from the output of the bistable circuit. A source providing a pulse train clocks the bistable circuit. A heat meter in which the input signal comes from a temperature sensitive bridge and the pulse train comes from a flow meter is described.

    摘要： 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.
