The Orange Research 2321 Series In-Line Flow Instruments operate on the difference between two pressures (delta-P). This delta-P develops as flow is established through a variable orifice which is formed between the spring-biased metering cone and the end cap in which the cone rests. The variable orifice allows the cone to move linearly in proportion to the delta-P. A magnet located on the metering cone moves with the cone and rotates a follower magnet located in a chamber adjacent to the fluid cavity. The gauge pointer is located at the end of the rotary magnet shaft and rotates with the magnet to provide gauge readings proportional to flow. There are no mechanical seals between the flow chamber and the rotary chamber. This is accomplished by coupling forces between two adjacent magnets through a solid wall.
