gas velocity sensor

Flow measurement - Wikipedia

Velocity times the cross-sectional area yields a flow rate which can be integrated into volumetric flow. There are two types of area velocity flowmeter: (1) wetted; and (2) non-contact. Wetted area velocity sensors have to be typically mounted on the bottom of a channel or river and use Doppler to measure the velocity of the entrained particles.

Gas flow measuring instruments | SICK

Whether for volume flow measurement, mass flow measurement or flow velocity measurement - the measuring tasks for determining gas flow are very diverse. On top of this, there are often rough ambient conditions in challenging areas such as flare gas measurement, tunnel monitoring or emission monitoring. The ultrasonic gas flow measuring devices from SICK are up to any challenge.

Stack Gas Velocity | E Instruments |

The gas velocity calculation is a function of several variables including the differential pressure of the stack gas, the stack gas temperature, and the absolute stack gas pressure. A Pitot tube can be used to measure the stack gas differential pressure. Download the Velocity Calculation (PDF, 84KB) worksheet for more information.

I do not think you are using the 641 series air velocity transmitter in an appropriate application. Any moisture or particulates in the exhaust could be causing damage to the hot wire sensor, leading to the failure. The difference in the sensors is probably why you got longer life out of the PFS series, which unfortunately, is no longer available.

Gas Pressure Sensor - Vernier

The Gas Pressure Sensor can be used to monitor pressure changes in a gas. The range is wide enough to perform Boyle’s law yet it is sensitive enough to conduct vapor-pressure or pressure-temperature experiments. Biology teachers can use the Gas Pressure Sensor to monitor transpiration or respiration in an enclosed environment.

Jan 11, 2003· velocity shown in Equation (3) refers to the velocity of each individual path. The velocity needed for computing volume flow rate, also know as bulk mean velocity, is the average gas velocity across the meter’s area. In the pipeline, gas velocity profiles are not always uniform, and often there is some swirl and asymmetrical flow
