Description

Battery Powered Digital Mass Flow Meters for Gases

The red-y compact series mass flow meters and regulators provide portability, flexibility, and convenience

The advanced compact unit can be equipped with various modules, including battery, power, alarm, or analog/pulse options. It is available in stainless steel or aluminum and features an intuitive backlit touch screen display, USB connectivity, and precise, reliable operation.

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.

Independent Operation
The red-y compact flow meters are powered by a standard AA battery. Optionally, 24 VDC and Micro-USB power supplies are available
Modular Extensions
4 expansion modules: Battery, Power Supply, Alarm, Analog/pulse out
USB Enabled
The red-y compact units can be powered with any common Micro-USB power supply (DIN62684) Device updates can be performed using the USB interface
MEMS Sensor
The MEMS semiconductor chip is the centerpiece of the thermal mass flow meter. Analog-digital conversion takes place in the sensor
Totalizer
In addition to the actual flow, the total consumption is displayed. Ideal for gas consumption measurements
1 Device – Multiple Gases
One red-y compact measuring device can be used for up to 3 different gases or gas mixtures
Wide Choice of Flow Units
Choose between a large number of standardized and normalized flow units of the Imperial, US customary and SI measuring systems (with user adjustable reference conditions). The units are selectable from the integrated menu both for the actual flow and the totalized flow
Password Protection
To avoid unauthorised change of settings, the menu of the new red-y compact can be locked with a password
Pressure & Temperature compensated
In contrast to variable area flow meters, the digital mass flow devices are insensitive to pressure and temperature changes
3-Year Warranty
High-quality components ensure long and trouble-free operation (does not apply to calibration, options and accessories)

The red-y compact is modular in design, allowing you to choose from various modules that can be added to the base model. The modules are interchangeable and can be added later, but only one module can be used at a time.

Battery module
The battery module is the default for the compact. With this module the compact can run on a single standard AA battery.
The unit also have a micro-USB connector that can be used as power supply and can also be used to update the firmware (See tab “Firmware”)
Power supply module
With the power supply module the compact can be powered from an external 15…30 VDC power source. The module comes with a 2 or 5 meter cable with fly leads
Power supply module with AC socket power supply
This power module comes with a wall plug socket power supply by which the unit runs of 100…250 VAC power. The module comes with a 1.5 meter cable and you can select a plug for EU, US, GB, AU or CN.
Alarm module
The alarm module option provides:
- 3 alarm contacts (relays up to 1 amp, 30 VDC)
- 2 optical isolated input channels (reset alarm)
- Every alarm contact separately settable as
  - High flow alarm
  - Low flow alarm
  - Window flow alarm
  - Totalizer alarm
- Hysteresis, delay and alarm duration time adjustable
- Built-in 15…30 VDC power supply, polyfuse protected
- 2 or 5 meter fly lead cable included
- All variables adjustable locally through touch screen
Analog/pulse module
The analog/pulse module provides:
- One active 4-20 mA output (adjustable 0-22 mA)
  - Load 1000 ohm @ 24 VDC power
  - Full customer configurable and certifiable
- Open collector pulse output
  - Frequency up to 25 Hz
  - Voltage pulse:1…30 VDC
  - Built-in 15…30 VDC power supply, polyfuse protected
