Precision Gas Metering for Demanding Applications

High Measurement Precision

Standard accuracy ranges from ±1% to ±0.5%, with high-precision models reaching ±0.2%. This level of accuracy makes it the preferred choice for trade settlement and applications requiring strict custody transfer standards.

Superior Repeatability

Short-term repeatability of 0.05% to 0.2% ensures consistent measurement across frequent cycles. This reliability is critical for online calibration and maintains high-frequency resolution for trade billing.

Wide Measuring Range

Features a range ratio of up to 1:20 for medium and large calibers, and 1:10 for small calibers. This allows for accurate measurement across varying flow rates without the need for frequent meter resizing.

Rugged Construction & High Pressure Resistance

Constructed with 304 or 316L stainless steel and hard alloy bearings for maximum durability. Specially manufactured units can withstand pressure levels of 10MPa, 16MPa, and up to 25MPa.

Advanced Intelligent Compensation

Utilizes three-point instrument coefficient correction to intelligently compensate for non-linearity on-site. This ensures the meter remains accurate and stable even in complex gas flow environments.

Explosion-Proof and Harsh Environment Ready

Certified to ExiaIICT4 and ExdIIBT6 explosion-proof grades for safe operation in hazardous gas zones. The anti-lightning and anti-interference design ensures signal integrity in high-noise industrial areas.
