Introduction Features Specifications Model Selection Application Installation

Introduction

Micro gas mass flowmeters are developed based on advanced sensing technologies such as FMEMS technology sensing chips for measuring and monitoring gas mass at small flows. Micro gas mass flowmeter can measure the flow of various gases, including air, nitrogen, oxygen, carbon dioxide, etc., widely used in medical, environmental protection, chemical and other fields. It has the characteristics of low power consumption, mobile design, tape display and network conventional metering.

Application field
a. Medical field: Micro gas mass flow meters can be used for clinical oxygen supply monitoring and metering in hospitals (such as medical oxygen meters), as well as gas flow monitoring in medical equipment such as ventilators and anesthesia machines, to help medical personnel monitor patients' breathing conditions in real time and adjust treatment parameters.

b. Environmental protection: In terms of environmental monitoring and control, the flow meter can be used to detect and measure the composition and flow of gases in the atmosphere, such as air pollutants, greenhouse gases, etc., to provide accurate measurement data for environmental protection departments and scientific research institutions.

c. Chemical field: In the chemical production process, the micro gas mass flow meter can be used to monitor and control the gas flow in the industrial process to ensure the stability and safety of the production process.

d. Scientific research field: In scientific research and laboratory environments, the flow meter can be used to measure and analyze the gas flow in laboratory equipment, such as gas chromatograph, mass spectrometer, etc., to provide reliable experimental results for researchers.

Features

Based on the thermal principle, the mass flow rate of the gas does not change with variations in ambient temperature and pressure.

The tubular diversion principle makes it convenient to change the range and easy to install.

Good sensor packaging reduces sensitivity to external temperature changes.

The measurement and control range is large, with the maximum full range reaching up to 30ln/min

It features short preheating time, small zero drift, high measurement and control accuracy, and is suitable for the measurement and control of very small flow rates.

It can communicate with the instrument through secondary instruments or PLC, and the operation is simple.

High precision: Better than 1%

It has a wide measurable range, from 1% to 100%

The response time is fast, better than 1 second

Installation

Note: When installing and using, it is necessary to ensure that the front pipe end and the back pipe end of the above distance are ensured, and the straight pipe section is concentric with the pipe on the flow meter, and ensure that the flow meter is fixed and reliable. If the straight pipe section cannot be guaranteed, the accuracy of the flowmeter cannot be guaranteed.
