Flow direction LEDs, 2

Input: DC pulse/frequency or dry contact output from

ONICON insertion or inline flow meters
Output: Additional output signal(s) ordered with flow

meter are available for connection to control system via the display module terminal strip.


Scaled Output: For totalization; scaled to a specific unit of volume per pulse (i.e. 10 gal/pulse).

Auxiliary output is in addition to any outputs provided by the flow meter. (DB-1202-01 only)


Factory programmed for specific application

Field programmable via front LCD interface MEMORY

Non-volatile EEPROM memory retains data in the event

of power loss. ENVIRONMENTAL

Operating temperature range: -20° to 140°F Operating humidity range: 0 to 85% RH




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.
