Measuring across a pump, chiller or coil, this wet differential pressure transmitter reads 0 to 30 psid through two stainless steel pressure ports rated for liquid service. A local LCD shows the differential without a service laptop. Metal-clad cables carry the sensors to the electronics, so the enclosure mounts away from the pipework it monitors and stays clear of the condensation that collects on a chilled line.

The ACI WPR2 Series is a remote wet-to-wet differential pressure transmitter built to cut installation time, often removing the need for extra plumbing and manifolds. The sensors sit at the taps and the electronics mount elsewhere, joined by cable rather than impulse tubing. Standard CMP-rated PVC cable is offered alongside a metal-clad option whose flexible conduit and 304 stainless steel construction resist abrasion, cuts and corrosion.
