Indication

Omega’s new DPF20 Series of

indicators offer real flexibility for

measurement of a wide range of

frequency or pulse inputs. The

display is easily configured to

indicate frequency, rate, period

or count. This makes the meter

ideal for flow applications where

they can display flow rate or total

from a variety of different flow

sensors. Or for quadrature signals,

to indicate angular position or

rotational speed and direction.

The DPF20 series offers

exceptional performance at an

economical price, with some

unique and powerful features,

summarized in the table on

page 3.
