Please correct me if I am going about this the wrong way, but my plan would be to pipe the positive port on the DP switch into the duct at the blower outlet and to pipe the negative port on the DP switch into the duct at the blower inlet. The J21K Series switch’s rugged design – with epoxy-coated enclosure and sealed metal bellows – lends itself to exacting applications. Flow rate measuring instruments measure the amount of substance that flows through a pipe cross-section per time unit. Differential Pressure Switch The J21K Series differential pressure switch monitors the difference between two system pressures or vacuums. Innovative DP transmitters and DP meters enhance your differential pressure flow measurement capabilities. As one of the most common technologies for measuring flow, differential pressure (DP) flow has a long history of achieving high accuracy and durability. Delta's Classic range is flexible enough to cope with most DP switch applications. Typical flow rate applications measure gases, vapours and aggressive or viscous liquids in pipelines as well as bulk solids on conveyor belts. By limiting differential pressure to the required value, this automatically and dynamically balances the network, ensuring that all consumers receive the specified flow.
