TF-4000
Description：
The TF-4000 series is a compact gas flow meter developed based on the proven measurement technology... one heated RTD is controlled to maintain a constant temperature difference... The heat transferred... is proportional to the mass flow rate... the mass flow rate is determined directly as a function of the required heating power.
