Integrated Manual Valve

Needle valve with 15 turns for precise flow adjustment

Modular Extensions

4 expansion modules: Battery, Power Supply, Alarm, Analog/puls out

USB Enabled

The red-y compact measurements instruments can be powered with any common Micro-USB power supply (DIN62684). Device updates can be performed using the USB interface  

High Accuracy & Dynamics

The devices offer high accuracy and a wide dynamic range:
Accuracy up to ± 1% of full scale
(depending on application/measuring range)
Turndown ratio 1 : 100

Extended Alarm Functions

The red-y compact 2 series provides 3 configurable alarms. The following triggers are available:
Low alarm, high alarm, window alarm and totalizer alarm
The alarms can be configured with different parameters:
Normally open, normally closed, hysteresis, auto/manual/remote reset, delay and alarm duration

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

High-precision Valve

In the red-y compact regulator / all-in versions with manual valves, high-precision needle valves are used. These valves allow fine adjustment of the flow rate

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)
