F235x Compact Thermal Mass Flow Meter
Description
Measurement Range：0.02 … 3000 SLM
Turndown Ratio：1:100
Characteristics
The F235 series is used to accurately measure the gas mass flow. It is based on thermal measurement technology. It can measure the mass flow directly, pressure and temperature compensation is not required. It integrates MEMS (Micro-Electro-Mechanical Systems), signal processing, digital simulation and other technologies
Its principle and technical foundation ensure the outstanding performance of the F235 series in terms of sensitivity, pressure loss, turndown ratio, response time and micro flow measurement. The F235 series displays flow consumption via a local display. Additionally, analog and digital outputs support remote data acces
Typical installation
● Based on the thermal flow measurement principle, it’s not required to compensate gas pressure and temperature, integrated temperature measurement
● Based on micro electromechanical systems (MEMS) made with CMOS semiconductor processes, enabling high-precision measurements in millimeter dimension
● Ultra-wide turndown ratio, lower limit can reach 0.04 SLM (DN3)
● Integrates digital adaptive signal processing technology to effectively suppress random errors
● The fully isolated electrical structure can completely filter out field disturbance
● Standard Modbus RTU (RS485) interface and 4 to 20 current output
