ASAIR AMS2106R02 CO₂ Gas Mass Flow Meter 1-100L/min Thermal Mass Flow Meter Supports Modbus-RTU

ASAIR AMS2106R02 CO₂ Gas Mass Flow Meter 1-100L/min Thermal Mass Flow Meter Supports Modbus-RTU

Description:
The digital gas mass flow meter is based on the thermal principle. It calculates the gas mass flow by measuring changes in resistance. The product features a self-developed MEMS flow sensor chip, delivering excellent accuracy across the full range. It offers outstanding performance, high stability and reliability, along with intuitive readings, precise measurement, strong resistance to both high and low temperatures, good linearity, and fast response.

It supports both battery power and external power supply, enabling flexible use and cumulative flow measurement. This meets customer demands for a high cost-performance solution.

Each unit undergoes rigorous testing and calibration before leaving the factory to ensure high-quality delivery.

Features:
* Digital gas mass flow meter
* Measuring range: 1-100 L/min, excellent repeatability
* Integrated measurement of mass flow and temperature
