These instrinsically safe and nonincendive, loop-powered 1/8 DIN flow rate/totalizers can be installed virtually anywhere to provide convenient and informative displays of flow rate and total from a 4-20 mA signal.

One of the most convenient features of these instruments is their ability to display both flow rate and total at the same time.

For instance, flow rate is typically displayed on the 5-digit alphanumeric top line and flow total or grand total is typically displayed on the 8-digit alphanumeric bottom line.

Both of these lines use 14-segment, alphanumeric characters for clear indication of tags, units or alarm messages.

Further enhancing the display on these instruments is a 20-segment bargraph available on the PD6624/6 that also includes a numeric value of the percentage the bargraph represents.
