Flow meter for H2S acid gas

Gases with high H2S content (>25%) like sour gas or biogas are hard to measure the flow rate. Corrosion from sour gas can erode pumping and refining equipment, piping, and instruments as well. Flow Measurement of Sour Gas is a tough job for customers; acid resistant flow meters are needed.Hydrogen Sulfide (H2S) is a naturally occurring gas found in crude oil, natural gas.

H2S gas can be toxic to humans, corrosive to metals and flammable. The measurement of H2S levels is important for both the safety of personnel and the integrity of industrial process equipment, infrastructure and pipelines

The metal rotor flowmeter is used to continuously measure the volume flow of liquid and gas in a closed pipeline. It has a solid structure and reliable flow measurement. It can be adapted to the measurement of various complex occasions and is widely used in flow measurement and industrial process control. Metal tube variable area flow meter has the option of PTFE wet parts, which provide the solution for h2s acid sour gas flow measurement options. It can be with digital display and output 4-20mA output. So it is also digital sour gas flow meter.

Main Feature for Metal rotor flow meter :

• Rugged all-metal structure Flowmeter
• Optional stainless steel, Hastelloy, titanium, PTFE material for different fluids measurement
• Low pressure loss
• Suitable for low velocity fluids flow measurement
• Low requirements for straight pipe sections when installing the gas sensor
• Can be sour gas flow meter indicator without any display, option with digital gas flow meter with outputs and LCD display
• Option with HART Protocol or RS485 (MODBUS RTU)
• Variable size available: 1/2” to 8” sour gas flow meter sensor
