This is the main part of our production system.  Our velocity control system with out our by pass valve. Better value and more productive than a valve only system, our system will let the operator know the true readings of the gauges. This is due to the unmodified flow without a valve. If a regulator valve is not used, we do recommend a manually operated emergency ” panic” valve used with our system. If you have a valve, you can add this to your current system.  System includes all sensors needed for operation. A Greyline doppler is standard for fps. A  Setra is used for psi and a Ashcroft for vacuum. We recommend a mag meter for the velocity control. This is due to at times the doppler signal can be erratic and the accuracy of a mag meter is much more stable.  A upgrade to a mag meter is a 5,000 adder.
