PLV-NF30 series mass flow meter/controller

The PLV-NF30 high-precision mass flow meter/flow controller adopts the principle of temperature difference calorimetry before and after capillary heat transfer to measure the mass flow rate of gas,

Not affected by temperature and pressure. Amplify the flow signal measured by the sensor and compare it with the set voltage,

Use the obtained difference to drive and control the regulating valve, and closed-loop control the flow rate through the channel to make it equal to the set flow rate.

1、 Product Overview

◆ Thermal principle, higher accuracy, faster response, with mesh port
