POWER AIR FLOW MEASUREMENT

The VAP Insertion Pitot is designed for easy installation, via ports, directly into new or existing duct work. Insertion of a VAP Pitot will ensure an accurate differential pressure output that allows for precise airflow measurement and control of your process.

The VAP Insertion Pitot performs particularly well in clean air applications as well as heavily particulate-laden applications such as the conditions found in many power plants. The unique design of the VAP-PA pitot reduces the potential of plugging from particulate such as fly ash found in the air stream. The VAP averaging pitot offers an economical and highly accurate method of measuring air flow in ducts with adequate upstream and downstream straight duct runs.

The High Beta Engineered, or (HBE), is designed to eliminate cyclonic, turbulent and reverse flow, while minimizing pressure loss in almost any installation, including those with relatively few or almost no straight duct runs either upstream or downstream. The HBE is a custom engineered product that is great for combustion air flow measurement in both round and square ducts that are non-standard in size and shape. The HBE is a perfect fit for applications in any industry, but is well suited for the irregular duct work seen in power plants for measuring combustion air flow including primary air, secondary air and over-fired air flow.

The QVT Multivariable Transmitter from Eastern Instruments is a Smart Transmitter that can be used for the accurate measurement of up to four separate process variables including Differential Pressure, Temperature and Absolute Pressure. When coupled with any DP based flow measurement element, the QVT will calculate the fully compensated mass flow of air/gas traveling through any process which is at or near atmospheric pressure (5 - 25 psia). The QVT is uniquely designed for high accuracy at low DP ranges. Its high accuracy is due in part to its unique process seal which requires no diaphragm seal. Due to condensate, diaphragm seals often cause inaccuracies in a transmitter's sensor readings.
