Precision Digital PD689 5 Digit Loop-Powered Rate/Totalizerr

5 Digit Loop-Powered Rate/Totalizerr

Through significant innovation in technology and design, we developed the Loop Leader® Series of loop-powered rate/totalizers, which are loaded with standard features and built for tough industrial environments.

Full Featured - Everything comes standard with these meters. The competition may charge extra for loop-powered backlighting, open collector output and programmable exponent capability, but these and a host of other key features are standard on these indicators.

Install Just About Anywhere - Indoors, outdoors, bright sunlight, dimly lit plant, wet, dirty, hot or cold, these indicators go just about anywhere. Their shallow-depth case, FM Type 4X front, loop-powered backlighting, and wide operating temperature range are all standard features. And the PD689 with its FM Approval and CSA Certification can be installed in just about any hazardous location.

Alternating Rate/Total Display - Press Enter/ACK button to alternate between rate and total or program the totalizer so the display automatically changes between displaying rate and total every 10 seconds. This feature is particularly useful if the meters are mounted inside a NEMA 4X or an explosion-proof enclosure.

Square Root Function - The square root extraction feature displays flow rate by extracting the square root from a differential pressure transmitter signal. The user selectable low-flow cutoff feature gives a reading of zero when the flow rate drops below a user selectable value.
