Aluminum alloy gas Roots flowmeter, pulse output intelligent gas waist wheel flowmeter
Aluminum alloy gas Roots flowmeter, pulse output intelligent gas waist wheel flowmeter I. Overview Intelligent gas waist wheel flowmeter is a new gene
Product details
1、 Overview
The intelligent gas waist wheel flowmeter is a new generation flowmeter that integrates flow, temperature, and pressure detection functions, and can automatically compensate for temperature and pressure. Gas is a compressible fluid, and its volume value is closely related to temperature and pressure. In order to unify the standards of both trading parties, it is necessary to convert the actual volume into the standard volume under benchmark conditions (101.325 kPa 20 ℃). To achieve this goal, an intelligent gas waist wheel flowmeter can correct the volume of gas. It is an ideal instrument for gas measurement in industries such as petroleum, chemical, power, and metallurgy.

Main features of the product:
Integrated with temperature, pressure, flow sensors, and intelligent volume correction, it can detect the temperature, pressure, and flow of the measured gas, and perform automatic flow tracking compensation and compression factor correction calculations.
Adopting microcomputer technology and high-performance integrated chips, the whole machine has powerful functions and superior performance.
The circuit adopts surface mounting technology, with a compact structure, strong anti-interference ability, and high reliability.
Pressure sensors, temperature sensors, and flow sensors are all built-in, making the structure more compact.
The micro power consumption high-tech adopted has low overall power consumption, which can be operated for a long time by the built-in battery or by external power supply.
According to the flow frequency signal, the instrument coefficient can be segmented and automatically linearly corrected, thereby improving the accuracy of instrument use.
Equipped with fault self diagnosis and alarm functions, high reliability, using LCD display, clear and intuitive, easy to read.
The flowmeter is equipped with pulse signal output and can also output 4-20mA standard analog signal according to user needs.
The instrument comes with a real-time database and can be paired with our factory's dedicated MODEM through the RS-485 communication interface to form a meter reading network, facilitating centralized data collection and real-time management.
The micro power consumption technology adopted has low overall power consumption and can run for more than five years using the built-in battery.
On site display of flow values with multiple signal output functions to meet the needs of different sites and systems.
Adopting E2PROM data storage chip to store user parameters, manufacturer parameters, and certain historical records.
Adopting a high contrast three row LCD display, it can display date, standard cumulative flow rate, standard instantaneous flow rate, medium temperature, pressure value, and battery voltage.
It has real-time data storage function, which can prevent data loss during battery replacement or sudden power outage. In the event of a power outage, internal parameters can be saved.
The intelligent gas waist wheel flowmeter is mainly composed of components such as a housing, a conjugate rotor, and an intelligent flow integrator. A pair of shared items installed in the measuring room
Under the pressure difference (P in>P out) of the circulating gas, the yoke rotor maintains the correct relative position of the rotor through the machined tuning gear. Continuous non-contact sealing is achieved by maintaining working clearances between rotors, rotors and shells, and rotors and wall panels. Every time the rotor rotates, it outputs four times the effective volume of the measuring chamber gas. The number of revolutions of the rotor is transmitted to the intelligent flow accumulator through a magnetic sealed coupling device and a reduction mechanism, thereby displaying the cumulative volume of the output gas. The measurement process and working principle are shown in Figure 2 (only a quarter cycle is shown in the figure).
