Digital mass flow meter/controller (economy type)

PLV-NF10 series digital mass flow meter/controller (economy type)

1、 Product Overview

◆ Thermal principle, fast response, high accuracy

◆ Tubular diversion, not easily blocked

◆ Suitable for various low-pressure and high-pressure pipelines

Short preheating time, small zero drift, and high reliability

◆ Digital input/output can be controlled and displayed using secondary meters or flow computers for flow control and display

The PLV10FD mass flow controller consists of components such as a mass flow sensor, laminar flow layering components, flow controller control valve, and amplification control circuit.

It is made by utilizing the heat transfer of flowing fluid to change the thermal conductivity distribution effect of measuring the temperature distribution on the capillary wall.

The PLV10FD mass flow controller adopts the principle of temperature difference calorimetry before and after capillary heat transfer to measure the mass flow rate of gas, which is 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.
