Incinerator Combustion Air Flowmeter

Do Not Overlook Operating Constraints

By David W Spitzer

S&B-LogoOnline —- “Flow measurement applications can be difficult because of physical properties, operating conditions, operating constraints or some combination of all three. For example, the fluid may be corrosive, abrasive and/or lethal. It may be operating near its vapor pressure or at an extremely high or low temperature or extremely high or low pressure.

“Selecting a flowmeter to measure even common fluids operating at non-extreme conditions can be challenging when operated under these conditions. That said, the operating constraints are often overlooked (at least initially).”

“Consider the measurement of combustion air to an incinerator.

“The ambient air was not corrosive, abrasive or lethal and operated at atmospheric pressure and ambient temperature. In other words, the air was benign and not operating at extreme conditions.

“Finding a flowmeter to measure the air flow should be easy, right?”
