For laboratory simulation of natural gas desulfurization of hydrogen sulfide, are there specialized rotameters for hydrogen sulfide?
Thread Content
I’d like to ask the experts here: I need to conduct experiments in the laboratory to simulate the removal of hydrogen sulfide from natural gas. Should I use a regular air-type rotameter or one designed specifically for hydrogen sulfide? It’s difficult to find rotameters designed for hydrogen sulfide online! Concerned that ordinary flowmeters may be corroded by acidic gases
Does no one know? Please help!
Flange-mounted vortex flow meter I. Overview The LUGB type vortex flow meter is a device that measures the volumetric flow rate, the volumetric flow rate under standard conditions, or the mass flow rate of gases, vapors, or liquids, based on the Karman vortex principle. It can also be used as a flow transmitter in automated control systems. This instrument utilizes advanced differential technology, along with measures such as isolation, shielding, and filtering, to overcome issues associated with similar products such as poor seismic resistance and noise in low-level signal data. It also employs unique sensor packaging techniques and protective measures to ensure the reliability of the product. The product is available in two versions: basic and composite; the basic version is used to measure a single flow signal ； Composite types can simultaneously measure temperature, pressure, and flow rate. Each type is available in integral and split configurations to suit different installation environments. II. Instrument Features and Applications
Features:
n No moving parts, ensuring long-term stability; simple structure that facilitates installation and maintenance.
n Equipped with noise-reduction circuits and vibration-resistant sensors, offering a certain degree of resistance to environmental vibrations.
n Utilizes ultra-low-power microcomputer technology; a single 3.2V 10AH lithium battery can provide power for over 5 years.
n Software is used to correct the non-linearity of the instrument’s coefficients, thereby improving measurement accuracy.
n Low pressure loss and wide measurement range.
n EEPROM is used to store cumulative flow data, providing power preservation for more than 10 years.
Applications:
This instrument can be widely used for measuring the flow rate of various media in large, medium, and small-scale pipelines for water supply and drainage, industrial circulation systems, sewage treatment processes, as well as oils, chemical reagents, compressed air, saturated and superheated steam, natural gas, and other fluids.
