YIDU EC gas mass flow controller

Description of YIDU EC

The EC series laminar gas mass flow controller differs from the SC series controller in that it does not have a touchscreen display. The technology is based on the laminar differential principle and is independent of the inlet flow conditions. Combined with high-precision pressure and temperature sensors that provide accurate pressure and temperature compensation, the product quickly reaches the set flow rate over a wide range of temperatures and pressures, ensuring measurement accuracy and control stability. Analog and digital communication methods are suitable for customers who perform related process control.

Features

• Ultra-Precision: ±0.5% reading accuracy for high-end manufacturing gas control;
• Wide range: 0.5SCCM~5000SLPM, covering all range ranges required by the industry;
• Universal Compatibility: Supports industry-standard communication protocols and fluid connections;
• Scalable Configurations: Optional high-temperature (-40°C~200°C), high-pressure (100 barg), low-pressure-drop, and fast-response (≤15ms) variants.

Principle Introduction

Laminar mass flow controllers leverage patented internally-compensated laminar differential pressure technology [Patent No.: ZL20151 0610447.5]. Equipped with integrated pressure and temperature sensors, they comprehensively compensate for discrepancies between volumetric and mass flow rates induced by thermal/pressure variations. Precision solenoid proportional valves automatically modulate gas flow according to setpoints, delivering exceptionally accurate and stable flow measurement and control.

Application

When precise gas flow control or automated production line integration is required, laminar mass flow controllers serve as essential instruments deployed across research laboratories and diverse industrial process automation systems, delivering superior stability and accuracy.
