Precision Digital Loop Leader® PD683 and PD688 5-Digit Loop-Powered Process Meters

There's nothing stripped down or bare bones about Precision Digital PD683 and PD688 loop-powered indicators; they're designed for demanding process control applications. Standard features include a full 5-digit backlit display with bargraph, on-screen custom engineering units, and max/min display capabilities. With square root and programmable exponent functions standard, the PD683 and PD688 indicators can display flow from a DP transmitter or open channel flow in weirs and flumes.

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. And, they can be scaled without a signal source for even quicker setup. The PD683 is for general-purpose applications and the PD688 is FM and CSA approved for use in hazardous area applications.
