Precision Digital Loop Leader® PD684 and PD689 5-Digit Loop-Powered Flow Rate/Totalizers

Precision Digital PD684 and PD689 loop-powered rate/totalizers can display rate up to five digits and total up to eight digits using a total overflow feature. The display can be programmed to automatically or manually toggle between rate and total. Standard features include a backlit display with bargraph, on-screen custom engineering units, max/min display and open collector output.

Even packed with features, they're still easy to setup and get running. Everything is programmed from the front panel buttons with no pots or jumpers to deal with. In fact, they can be scaled without a signal source for quick setup. The PD684 is for general-purpose applications and the PD689 is FM and CSA approved for use in hazardous area applications.
