DESCRIPTION
The DB-1200 series displays are modular display centers that convert an ONICON bi-directional insertion turbine or bi-directional insertion electromagnetic flow meter into a complete flow monitoring station. The steel, wall mounted module displays the current flow rate and
total and provides an indication of flow direction. It also provides a low voltage DC power source for powering the flow meter.
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 for connectivity to other remote devices such as BTU meters, building control systems, and data acquisition systems.
DB-1200 series display modules are specifically designed for bidirectional flow applications. For standard flow applications see the D-1200 series display module.
APPLICATIONS
• Primary / secondary decoupling loop (bypass)
