Electronic Gas Volume Meter

Facilitates sampled volume measurement in compliance with US EPA requirements.

Flow and sampled volume measurements are of fundamental importance in air pollution monitoring particularly in stack emission monitoring. US EPA has stipulated a number of requirements with respect to range, accuracy and stability for dry gas meters. Dry gas meters are mechanical volume totalizers which are now being replaced by their electronic counterparts.

Physical Design Highlights

Model PSI–EGVM1 employs a precision orifice for flow measurement. The pressure drop that develops across the orifice is measured by a low pressure solid state pressure sensor. It takes advantage of multi-point linearization technique to enhance accuracy and the dynamic range of measurements. The flow and volume measurements are continuously displayed on a digital LCD module. The instrument also has a provision for manually resetting the totalized volume to zero.

Salient Features :

  • Digital Display of Flow and Volume
  • Online Integration of Flow
  • Fully Portable
  • Flow Accuracy ± 2% of Full scale
  • Wide Measuring Range
  • Precision Orifice Flow Sensor
  • Measures Flow from Pressure or Vacuum Source
