Manufacturer of digital display gas turbine flowmeters
The gas intelligent turbine flowmeter is a new generation of high-precision and high reliability precision measuring instrument developed in accordance with the ISO9951 standard and combined with advanced technology of flow meters at home and abroad. It integrates temperature, pressure, flow sensors, and intelligent flow integrators. Its excellent low-pressure and high-pressure measuring performance, multiple signal output methods, and low sensitivity to fluid disturbances make the flowmeter an excellent measuring instrument that can accurately measure the cumulative amount of gas.
Working principle of gas turbine flowmeter
The core component of a gas turbine flowmeter is the turbine rotor. When gas flows through a flowmeter, the kinetic energy of the gas causes the turbine rotor to rotate. The speed of the turbine is directly proportional to the flow rate of the gas. The flowmeter is equipped with sensors inside, which can monitor the speed of the turbine in real time and convert it into an electrical signal, ultimately displaying the flow value.
The working principle of gas turbine flowmeter can be summarized as the following steps:
Gas inflow: Gas enters the flowmeter through the inlet.
Turbine rotation: Gas flow causes the turbine to rotate, and the speed is proportional to the flow rate.
Signal conversion: The speed of the turbine is converted into an electrical signal through sensors.
Traffic display: After processing, the electrical signal is displayed as the traffic value.
Classification of gas turbine flow meters
- Gas turbine flow sensor/transmitter: This type of turbine flow product itself does not have on-site display function, only transmits and outputs flow signals remotely. Flow signals can be divided into pulse signals or current signals (4-20mA); The instrument is inexpensive, highly integrated, and compact in size, making it particularly suitable for use with computer control systems such as secondary displays, PLCs, and DCS. This type of turbine flowmeter is an explosion-proof product, with an explosion-proof rating of: ExdIIBT6.。
Application scenario: It can be used as a collection instrument for working condition flow signals, transmitting flow signals remotely to the upper computer - Intelligent integrated gas turbine flowmeter
Integrated intelligent instrument, using dual row LCD on-site display, has obvious advantages such as compact mechanism, intuitive and clear reading, high reliability, no external power interference, lightning resistance, and low cost.
Application scenarios:
- As an industrial control instrument in working conditions where temperature and pressure are relatively stable.
- In working conditions where temperature and pressure are relatively stable, users can calculate the standard flow rate based on the gas equation of the instrument readings.
- Intelligent temperature and pressure compensation integrated gas turbine flowmeter
The gas turbine flowmeter is equipped with temperature and pressure sensors, as well as an intelligent flow integrator. Through a microprocessor unit, the real-time collected flow, temperature, and pressure signals are compensated for temperature and pressure according to the gas equation, and the compression factor is automatically corrected. Then, the volumetric flow rate under standard conditions is displayed intuitively.
