This article introduces a digital flow pulse signal.The ITRON electronic correction instrument. Our understanding of nature largely relies on detection and instruments. Flow detection has always been an important part of industrial production process control, closely related to the national economy, national defense construction, industrial production, and scientific research. Especially in today's world, where energy is highly scarce and the degree of industrial production automation is increasing, millions of flow meters are needed in the collection, processing, storage, transportation, and distribution of natural gas, some of which involve settlement figures. To measure more accurately, it is necessary to conduct online detection of gas temperature, pressure, and flow signals. Automatic correction of the compressibility factor and automatic tracking compensation of flow convert the working condition volume into standard state volume. Against this background, the ITRON electronic correction instrument has emerged.

The ITRON electronic correction instrument is an intelligent secondary instrument that integrates temperature sensors and pressure sensors, featuring gas pressure and temperature detection display, directly converting the working condition volume flow and total volume of the flow meter into standard state volume flow and total volume, and has multiple signal output interfaces. The ITRON electronic correction instrument collects the pulse signals from the flow meter and calculates the uncorrected working condition volume flow based on the set pulse equivalent value. Technicians have provided an ITRON electronic correction instrument with a digital flow pulse signal, which can effectively solve the problems in the background technology. To achieve the above objectives, the technical solution adopted by the technicians is: an ITRON electronic correction instrument with a digital flow pulse signal, including a shell, external power supply, Internet of Things module, and user device, with a CPU microprocessor, pulse correction module, flow sensor, second preamplifier, and temperature pressure module installed inside the shell. The pulse correction module includes a first preamplifier, first memory, and MCU microprocessor, while the temperature pressure module includes a digital pressure sensor and a digital temperature sensor.

The pulse correction module also includes a first built-in power supply, with the input port of the first preamplifier electrically connected to the output port of the flow sensor.The signal port of the MCU microprocessor is electrically connected to the output port of the first preamplifier, the input port of the CPU microprocessor is electrically connected to the output port of the MCU microprocessor, and both the first preamplifier and the MCU microprocessor are connected to the first built-in power supply via wires. The input port of the second preamplifier is electrically connected to the output port of the flow sensor, the input port of the CPU microprocessor is electrically connected to the output ports of the second preamplifier and the temperature pressure module, and the input port of the LCD screen is electrically connected to the output port of the CPU microprocessor.

Compared with the existing technology, the beneficial effects of this utility model are: having a digital flow pulse signal.The ITRON electronic correction instrument has low power consumption control, data transmission, and other functions, with a simple structure and low failure rate; in addition, this device is small in size, integrated into the ITRON electronic correction instrument, requiring no additional installation, and its performance is superior to traditional methods.
