[0006] However, this creates variances, and the creation of variances during manufacturing should be postponed as far down the value chain as possible
On the other hand, configuring utility meters during installation may increase the risk of installation errors leading to erroneous consumption measurements

Embodiment Construction

[0027] figure 1 A schematic diagram of a utility meter 1 for measuring thermal energy delivered to a point of consumption by a fluid supplied via a supply flow 20 and a return flow 21 is shown. The utility meter includes a calculator device 10 that receives flow information from a flow meter unit 13 and temperature information from a pair of temperature sensing probes 11 , 12 .

[0028] In the illustrated embodiment, a flow meter unit is installed in the return to measure the return flow rate of the fluid. In another embodiment, a flow meter unit may be installed in the supply stream to measure the supply stream flow rate. Install temperature sensing probes to measure the temperature of the supply and return streams, respectively.

[0029] In the illustrated embodiment, the calculator device 10, the flow unit 13 and the temperature sensing probe are shown as separate units connected by cables. However, two or more of these devices may be integrated into one common device, a...

Abstract

Utility meter for measuring thermal energy delivered to a point of consumption by a fluid supplied via a supply flow and a return flow, including a flow meter unit for measuring a supply flow rate or return flow rate of the fluid; a pair of temperature sensing probes for measuring temperatures of the supply flow and the return flow, each of the temperature sensing probes including a resistive temperature device; and a calculator device configured for executing a measuring algorithm for determining an amount of thermal energy delivered to the point of consumption over a period of time based on flow rates and temperatures received from the flow meter unit and temperature sensing probes, respectively; wherein the calculator device is configured to detect the type of resistive temperature device included in the temperature sensing probes and to adapt the measuring algorithm according to the type of resistive temperature device.

Description

technical field [0001] The present invention relates to a utility meter for measuring thermal energy, such as heating or cooling, configured to autonomously detect the type of temperature sensing probe connected to the meter. Background technique [0002] Utility meters are used to measure fluid flow and consumption in utilities such as heating, cooling or water. Utility meters, such as heat meters for heating or cooling, measure flow and calculate consumption over time. When measuring heat or cold energy delivered to the point of consumption, both flow and temperature must be measured to determine the consumption. Flow can be measured using various techniques such as mechanical flow meters and ultrasonic flow meters. Temperature can also be measured using various techniques such as thermocouples, thermistors, or resistance temperature devices (RTDs). [0003] Temperature sensing probes utilizing resistive temperature devices are commonly used due to their accuracy and lo...
