Can these meters be used with flammable gases?
Flow meter, mass flow controller, mass flow meter, flowmeter...Sierra mass flow systems without the FM approval are not designed for use in hazardous or explosive environments. Do not confuse a “hazardous environment” with flowing gas inside a closed system, such as your plumbing, into pressure and flow measuring instruments. Customers regularly use the 800 series flow meters with flammable gases such as CH4, C2H6, C3H8, and H2 that is plumbed in accordance with proper safety measures.
Related QuestionsCan these meters also be used with gases other than N2?
Flow meter, mass flow controller, mass flow meter, flowmeter...All Sierra flow meters are calibrated with N2 unless otherwise specified. The reason is the “K-Factor” for other gases is nearly linear when one goes from N2 to almost any other gas. Other gases scale the signal and generate a slight offset. For each type of gas, this effect can be calculated and compensated by using a relatively simple "K-Factor".
Related QuestionsCan these meters be used in pulsating flow conditions?
Flow meter, mass flow controller, mass flow meter, flowmeter...The Sierra flow meters are regularly used in these conditions without noticeable problems. This is because the design of the flow meter is such that conditioning elements within the flow meter virtually eliminate the sensitivity to such pulsations. Many other flow technologies, such as "Delta Pressure" devices suffer from sensitivity to pulsations because the flow is not conditioned prior to measurement.

Related QuestionsIs LNG flammable?
LNG - Frequently Asked QuestionsWhen cold LNG comes in contact with warmer air, it becomes a visible vapor cloud. As it continues to get warmer, the vapor cloud becomes lighter than air and rises. When LNG vapor mixes with air it is only flammable if it's within 5%-15% natural gas in air. If it's less than five percent natural gas in air, there is not enough natural gas in the air to burn. If it's more than 15 percent natural gas in air, there is too much gas in the air and not enough oxygen for it to burn.

Related QuestionsWhat are gases?
FAQ Air chemistry and physicsAll chemical elements can be found in several different states (phases). One of these phases is the gaseous phase. Apart from gaseous an element can also be solid or liquid. Water is called ice when it is solid, it is wet when it is liquid, and when it is gaseous it exists merely as gas or steam. When temperatures rise, the molecules of a substance part, causing the substance to become gaseous and less visible. This phase change causes air to be invisible.

Related QuestionsWHICH FUELS (gases) CAN BE USED FOR PEM FUEL CELLS?
Hoku Scientific, Inc.Hydrogen is the primary fuel source which can be used directly in a PEM fuel cell. Other fuels that can be used include methanol, ethanol, natural gas, coal gas, gasoline and other fuels containing hydrocarbons. PEM fuel cells today are running on many different fuels, even gas from landfills and wastewater treatment plants. Using a fuel other than pure hydrogen requires a reformer or fuel processor.
Related QuestionsWhere do greenhouse gases come from?
ETF FAQsGreenhouse gases are emitted from a variety of natural and anthropogenic (human) sources. Carbon dioxide has the greatest effect on climate change because of its abundance. CO2 is emitted from the burning of fossil fuels (coal, oil, and natural gas), solid waste incineration, and wood burning (deforestation). Only a small proportion of CO2 emissions come from natural sources, such as plant decay, volcanic eruptions, and animal respiration (BBC 2004).

Related QuestionsHow accurate are peak flow meters?
Frequently Asked QuestionsWhen used correctly, peak flow meters are excellent tools that reflect the state of the child's asthma - but you need to treat the device with respect. Keep it clean, use it as directed, check it frequently for damage, and it will give accurate measurements. However, remember that symptoms are just as important as numbers. In some cases, children can get a good peak flow "score" even when they are having symptoms. If that's the case, make a note of the numbers and talk to your doctor.

I-Strip offers a unique and affordable paint removal system ...You should always protect you and your employees from unwanted fumes or dust when removing paint. It is more important to use a respirator for indoor applications, as there is less air exchange inside than outside. It is important to note that at the low operating temperature of 100 to 200 degrees c no plumbic (LEAD) gas is produced as this only occurs at temperatures in excess of 325 degrees.
Related QuestionsDavid Suzuki Foundation: Climate Change: FAQsGreenhouse gases trap heat in the earth's atmosphere. Without these gases, the earth's temperature would not support the variety of life on this planet. But when we burn large amounts of fossil fuels such as oil, coal and gas, we are dramatically increasing the atmospheric concentration of these gases. Like the glass in a greenhouse, this raises the average air temperature in the lower atmosphere. More energy is retained as heat or manifested as increased atmospheric activity.Related Questions
Q.: Why are flammable solvents and other chemicals getting to be such a problem to buy?
Star Graphic Supplies - Frequently Asked Questions (Page 1)A.: I’ve been noticing this trend in recent years, and it’s only going to escalate. Manufacturers are yielding to intense scrutiny and pressure from various safety and health agencies plus the escalating cost of fire insurance. The fast drying non-flammables are pretty much already gone due, in part, to their carcinogenic nature and the potential for long term liability to those either manufacturing them or condoning their use.
