Learn More VAP Velocity Averaging Insertion Pitots

Velocity Averaging Pitot for Differential Pressure Measurement in Industrial Applications
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 is designed to perform particularly well in both clean air applications and in heavily particulate-laden applications and can be adapted for use in applications where pitot freezing is a concern. If you are looking for an economical and highly accurate method of measuring air flow in ducts with adequate straight duct runs upstream and downstream, the VAP Insertion Pitot is a great choice.


Learn More About the DSV Flanged Duct Section VAP

Flanged Spool Section containing an array of VAP Velocity Averaging Pitots
The DSV, or Duct Section VAP, incorporates straightening vanes and a VAP Pitot array within a spooled duct section to make installation of the VAP Pitot even easier. The DSV can be quickly bolted in place for new ductwork or can be retrofitted into existing duct work for simple and accurate air flow measurement. Designed for both clean air and particulate-laden air flow measurement applications, the DSV is an accurate, no-hassle air flow measurement device for ducts with adequate straight duct runs upstream and/or downstream.


Learn More About the HBP High Beta Flow Conditioner

Flanged Spool Section containing flow conditioners, flow profilers and an array of VAP Velocity Averaging Pitots
As not all ductwork allows for proper upstream and downstream straight duct runs, a flow conditioning device is often needed for profiling air flow at the point of flow measurement. The High Beta® Process (HBP) Flow Conditioner is a proprietary-designed flow conditioning device, 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 High Beta® integrates flow-straightening vanes and a flow-profiling section with the precise measurement accuracy of the VAP Pitot to offer flow conditioning and accurate air flow measurement, even when placed directly downstream of an elbow, damper or other duct obstruction. The HBP comes in standard sizes that allow the delivery of accurate air flow measurement without the longer lead times associated with custom designs.


Learn More About the QVT Multivariable Transmitter

QVT Multivariable Differential Pressure Transmitter with RTD Temperature Sensor
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.
