Overview

Liaoning Xinruipeng Environmental Protection Gas Turbine Flow Meter belongs to precision velocity flow meters. Its working principle is based on the law of conservation of fluid momentum, and its core is to accurately measure the flow rate by capturing the energy of gas flow. It is known as the "precision pulse monitor" for industrial gas pipelines. When the measured gas flows through the flowmeter, it first passes through the rectification device inside the meter to optimize the gas velocity distribution profile and reduce turbulence interference. Then, the gas impacts the turbine blades, driving the turbine rotor to rotate at high speed. Within a certain flow range, the rotational speed of the turbine is strictly linearly related to the average gas flow rate, with higher flow rates resulting in faster turbine speeds.

1、 Core Measurement Principles

Liaoning Xinruipeng Environmental ProtectionGas turbine flowmeterBelonging to precision velocity flow meters, its working principle is based on the law of conservation of fluid momentum, and its core is to achieve accurate measurement of flow by capturing the energy of gas flow. It is known as the "precision pulse monitor" for industrial gas pipelines. When the measured gas flows through the flowmeter, it first passes through the rectification device inside the meter to optimize the gas velocity distribution profile and reduce turbulence interference. Then, the gas impacts the turbine blades, driving the turbine rotor to rotate at high speed. Within a certain flow range, the rotational speed of the turbine is strictly linearly related to the average gas flow rate, with higher flow rates resulting in faster turbine speeds.

The product is equipped with a high-sensitivity magneto electric induction sensor, which adopts a non-contact detection method to accurately capture the rotational frequency of turbine blades and convert it into a proportional electric pulse signal. After the signal is shaped, filtered, and counted by the intelligent transmission module, combined with the data collected by the built-in high-precision temperature and pressure sensors, it is dynamically compensated through the gas state equation and automatically converted into instantaneous flow rate and cumulative flow rate under standard conditions [6].

To ensure measurement accuracy and long-term stability, the core components of the product have been precisely optimized: using lightweight high-strength aluminum alloy turbine blades, designed from a fluid mechanics perspective to reduce gas impact energy loss, ensuring sensitive start-up at low flow rates and stable rotation at high flow rates; Equipped with wear-resistant self-lubricating bearings, significantly reducing rotational friction resistance, minimizing measurement drift caused by mechanical wear, and extending service life [6]; The sensor adopts anti-interference design, which can effectively resist electromagnetic interference from on-site frequency converters, high-voltage equipment, etc., ensuring the accuracy of pulse signal acquisition [6], and building a solid foundation for measurement accuracy from the hardware level.
