Digital Gas Mass Flow Meter MF5700 Portable Thermal Air Flowmeter 0-200L/min RS485 MEMS for Lab

Introduction

MF5700 is a portable MEMS thermal gas mass flow meter with a measuring range of 0 to 200 L/min. It offers high accuracy of ±(2.0% + 0.5% FS) and a fast response time of ≤0.1 second. The device features an LCD display for real-time flow reading, RS485 Modbus output, and flexible power options (8-24V DC or battery). Its compact and handheld design makes it easy to install and use for various gas flow measurement applications.

Application Range

MF5700 is widely used for measuring non-corrosive gases such as air, nitrogen, oxygen, and argon. Typical applications include laboratory gas analysis, hospital oxygen monitoring, industrial compressed air measurement, factory gas flow testing, and micro flow monitoring in analytical instruments. It is also suitable for gas flow control systems, environmental monitoring, and portable field testing.
