FAQ
Q1: Can this meter measure other gases besides nitrogen?
Yes, the meter can measure a wide range of gases, but the specific material compatibility and pressure rating should be verified for each application.
Q2: What is the accuracy of the high pressure version?
While not explicitly stated, Coriolis mass flow meters from our company achieve accuracy up to 0.1% in other applications, and similar performance is expected.
Q3: Is the meter suitable for outdoor installation?
With IP65 protection, it is suitable for outdoor installation, but it is recommended to protect from extreme weather conditions.
Q4: What output signals are available?
The meter supports 4-20mA, pulse, frequency, MODBUS RTU, HART, Profibus-DP, and Profibus-PA.
Q5: Can the meter be calibrated for specific gas types?
Yes, pre-shipment calibration tests are available and can be customized to your process conditions.
