DESCRIPTION
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.
APPLICATIONS
• HVAC chilled water, condenser water, and heating hot water flow monitoring
• Domestic water flow monitoring
• Natural gas monitoring
• Compressed air monitoring
• Process flow monitoring in industrial plants
• Municipal water flow monitoring
