Gas Gravitometers

Gas Gravitometers
Gravitometers measure the specific gravity of gases as compared to air. For many industrial process gases there is a definite connection between the analysis of the gas mixture and its specific gravity. When the specific gravity is involved in the analysis of the total mixture, or when the instruments are used with orifice metering in gas volume, they are graduated in specific gravity. When the gravimetric principle can be applied, Ranarex gravitometers excel over more complex and costly analyzers in total performance.

Eliminates span drift to ensure permanently accurate calibration.

Advanced design develops large measuring forces and is virtually friction-free.

Has Fast Response
Gas sample flows continuously at a high rate through a small measuring chamber that purges rapidly.

Durable, corrosion-resistant materials. Outer case protects against dust, humidity, and shock.

Low Cost
Simple design for low equipment cost; simple piping and wiring for low installation cost; rugged construction for low maintenance cost. These features ensure lowest long-term, total cost.

Easy to Use
Completely mechanical and easily understood. Installation requires only piping or tubing and electrical power. No special skills required.
