Wet Gas Flow Meter

Precision Drum-Type Gas Meters Royreal SQB Series

The Royreal SQB series precision drum-type gas meters operate on the displacement principle. The measuring drum, which rotates in a sealing liquid (distilled water or specialized oil), measures the volume of gas passing through the meter by periodically filling and emptying stationary measuring chambers. SQB series meters feature a wide flow range of 1:300 and high repeatability of at least 0.1%.

Their high accuracy and stability make SQB meters suitable for use in research laboratories, environmental analysis, sample preparation for determining the mass concentration of mechanical impurities, and the mass concentration of hydrogen sulfide and mercaptan sulfur in natural gas.

They are widely used in chemical-analytical laboratories in the oil and gas, energy, chemical, pharmaceutical, and metallurgical industries. They can also be used as a reference during verification and calibration of gas meters.

Accuracy of SQB Gas Meters:

Standard flow range: ±0.1%
Full flow range: ±0.15%

Materials of the Meter Body and Measuring Drum:

Stainless steel 304 (304L)
Stainless steel 316 (316L)
