Touch Technology
The touch display offers intuitive navigation. All device parameters can be adjusted through the integrated menu. Automatic display orientation adjustment via position sensor.
High accuracy & dynamic performance
The flow meters offer high accuracy and dynamic range:
Accuracy ±1% of full scale
(dependent on application/range)
Dynamic range 1 : 100
Advanced Alarm Functions
The new red-y compact features 3 configurable alarms. The following alarm modes are available: Max Alarm, Min Alarm, Range Alarm, and Totalizer Alarm
The alarms can be configured with different parameters: Normally open (NO), normally closed (NC), hysteresis, reset (automatic/manual or via input contact), alarm delay, and alarm duration.
High-precision Valve
In the red-y compact regulator / all-in version with manual valves, high-precision needle valves are used. These valves allow fine adjustment of the flow rate.
The new red-y compact 2 series is available with an alarm function module.
The models GCS (red-y compact 2 switch) and GCA (red-y compact 2 all-in) provide 3
configurable alarm relays. The following triggers are available: High alarm, low alarm,
window alarm and totalizer alarm.
The alarm module can be retrofitted on existing red-y compact 2 meters & regulators.
Features:
» 3 alarm contacts
(relays that can switch up to 1 amp, 30 Vdc)
» 2 optical isolated input channels
(to optionally reset an alarm remotely)
» Every alarm contact separately settable as high,
low, window or totalizer alarm
» Hysteresis, delay and alarm duration time all
customer configurable
» Built-in 8…30 Vdc power supply, polyfuse protected
» 2 meter fly lead cable included
» All variables adjustable locally through touch screen
Modification kit for GCM/GCR (SN > 300000):
