Sensocon, Inc., a leader in differential pressure, air velocity, and flow products, has a unique product line that offers a variety of solutions for our customers.  One application is measuring velocity or flow in HVAC ducts and similar applications.  Our Series A4 Digital Differential Pressure Controllers along with our FloSen® Airflow Probes make an excellent combination for measuring velocity and displaying it in real time.  The Series A4 Digital Differential Pressure Controller has many features that make the gauge one of Sensocon’s most popular products.  One such feature is the Series A4’s ability to calculate and display velocity or flow.  Using a flow sensing device, the Series A4 uses the velocity pressure from the device to calculate the velocity of the flow source.  Our FloSen® Airflow Probes are one type of flow sensing device that works well with the Series A4.  The FloSen® Airflow Probes are able to measure the total pressure and static pressure.  The Series A4 will then measure the difference which is velocity pressure and then calculate and display real time velocity or flow.   For more information on our Series A4 Digital Differential Pressure Controllers and our FloSen® Airflow Probes, you can visit their product pages below.
