Variable Area vs. Fixed OrificeOur fixed-orifice models are best for low-flow applications. They are able to measure down to 2 GPH, so small changes in flow rate can be seen and users alerted. Because these models use a fixed orifice, users must consider two factors: abrasive fluids and fluids that may leave deposits. This can affect accuracy over time by changing the size of the orifice. Our variable-area models use a larger orifice and a moveable flow cone, which reduces the potential for clogging. We offer specially designed flow cones for use under harsh conditions where dirt and debris may be present, such as in wastewater or construction site environments. Another benefit is the variable-area sensor allows for readings on a linear scale, often preferred over square root meters. Our 3000 Series is a fixed set-point flow switch. Their compact size and basic profile results in low-cost switches that can be mounted where space is limited. This makes them popular for OEM applications where simple flow switch actuation is required.
