ECO FLOW-300M

Digital mass flow meter (Mid-Range)

Product Introduction

ECO FLOW digital mass flow meter consists of a mass flow sensor, laminar flow stratification components, flow controller regulating valve and amplification control circuit. It uses digital signal input and output and has the characteristics of short warm-up time, small zero drift and high reliability.

 Product Application

• Thermal principle, fast response, high precision
• Tubular shunt, not easy to clog
• Applicable to various low-pressure and high-pressure pipelines
• Short preheating time, small zero drift, high reliability
• Digital input/output can use secondary meter or flow computer to control and display flow

ECO FLOW mass flow controller is composed of mass flow sensor, laminar flow stratification parts, flow controller regulating valve and amplification control circuit. It is made by using the heat transfer effect of flowing fluid to change the temperature distribution of the capillary wall.

ECO FLOW uses the principle of temperature difference calorimetry before and after capillary heat transfer to measure the mass flow of gas, which is not affected by temperature and pressure. The flow signal measured by the sensor is amplified and then compared with the set voltage. The difference is used to drive the control valve to close the loop and control the flow through the channel to make it equal to the set flow.
