Process Instruments was founded in 1988. They are headquartered in Bakersfield, California which is the heart of heavy oil production and thermal steam flood activities. They are a privately held corporation and currently doing business in California and Oman. Being the first to offer validation of well test systems, they have developed a very simple but state of the art portable well test system. PI’s units provide a separator design system which utilizes a combination of a vertical and horizontal separator, optimizing the gas-vapor/liquid separation. We also have a large flow range capability for both liquid and gas-vapor streams. The gas-vapor stream utilizes E+H Vortex meters, capable of measuring both low flow and high flow gas-vapor rates. Our liquid meters are E+H Coriolis Mass meters (PWT) and Vortex meters (SMT) which are extremely accurate.
