D-1200 series displays are modular ﬂow display centers that convert ONICON insertion and inline ﬂow meters into complete ﬂow monitoring stations. The steel, wall mounted modules display the current ﬂow rate and total and provide a low voltage DC power source capable
of powering most ONICON inline and insertion ﬂow meters.
The versatile display module can be located close to the ﬂow meter or up to several hundred feet away. Using the ﬂow meter with the display module will also allow you to support other remote devices such as Btu meters, building control systems, and data acquisition systems.
D-1200 series display modules are not designed for bidirectional ﬂow applications. For bidirectional ﬂow applications see the DB-1200 series display module.
