The gas intelligent turbine flowmeter is designed according toISO9951A new generation of high-precision and highly reliable precision measuring instruments that integrates temperature, pressure, flow sensors, and intelligent flow integrators, developed in accordance with advanced technologies for flow meters at home and abroad. Its excellent low-pressure and high-pressure measuring performance, multiple signal output methods, and low sensitivity to fluid disturbances make it an ideal choice have to Flow meters have become an excellent commercial trade measuring instrument that can accurately measure the cumulative amount of gas.

Functional FeaturesFunctional Characteristics

satisfy ISO9951The standard technical requirement is that the length of the table body is3DN（DNThe diameter of the flowmeter is measured and subjected to high and low level disturbance tests;·Can detect the temperature, pressure, and flow rate of the tested gas and display it under standard conditions（Pb =101.325KPa,T b =293.15K

）Accumulated gas volume;1 Wide flow range

Good repeatability, high accuracy, low pressure loss, and low initial flow rate;2

It has the function of setting five instrument coefficients and automatic correction;3Adopting patented integrated rectifier( utility modelPatent numberZL · 4) Low installation requirements for the front and rear straight pipe sections of the flowmeter(Previously)≥ 2DN

No downstream requirements);4Built in pressure and temperature sensors, high safety performance, compact structure, and beautiful appearance(Design Patent Number:

ZL 0333226 2·7)5Capable of self diagnosing faults in pressure and temperature sensors and displaying them directly on the screenLCD

Screen and upper computer;6A lithium battery can be used continuously for more than two years and has a two-level alarm output function for battery undervoltage, which is more suitable for use withIC

Supporting use of card management system;7The intelligent flow integrator can be positioned at any angle (with a rotation angle of)350°
