● Meet the technical requirements of ISO9951 standard

The length of the meter body is 3DN (DN is the nominal diameter of the flow meter, with DN250 and DN300 diameters of 1.5DN), and it has undergone high and low level disturbance tests.

● Wide flow range

Wide flow range (Qmax/Qmin=20:1), good repeatability, high accuracy (up to 1.0 level), low pressure loss, and low starting flow rate.

● Adopting integrated design

The use of integrated leading fluid can eliminate fluid disturbance, achieve significant rectification effect, and minimize pressure loss, requiring low installation requirements for the front and rear straight pipe sections of the flowmeter.

● Adopting modular design

Extract type independent core component module, compact structure, easy installation and maintenance, not affected by pipeline stress; An independent shell component module that can perform air tightness testing separately, simplifying the process; Independent fuel pump and header components, with strong interchangeability between different calibers, compact structure, and easy maintenance.

● Automatic traffic tracking compensation and compression factor correction

It can directly detect the temperature, pressure, and flow rate of the tested gas, perform automatic flow tracking compensation and compression factor correction, and display the accumulated gas volume under standard conditions (Pb=101.325kPa, Tb=293.15K).

● Long service life

A set of lithium batteries can be used continuously for more than five years and has a two-level alarm output function for battery undervoltage, which is more suitable for use with IC card management systems.

● Convenient for reading

The intelligent volume correction instrument can be positioned at any angle (with a rotation angle of 350 °), making it easy for the flowmeter to read under various installation conditions.

● High protection level

The instrument has explosion-proof and protective functions, with the explosion-proof mark of Ex ia IIC T4 Ga and a protection level of IP66. According to user requirements, GSM network functions can be provided to achieve low-cost long-distance wireless data transmission.
