PSMF50 Gas Flow Meter with Modbus RS485 for Methane/Hydrogen/LPG, Thermal Massis a precision instrument designed for measuring gas flow in industrial pipelines and process systems. It is widely used for compressed air monitoring, gas consumption measurement, energy management, and process control applications. Key features include thermal mass flow sensing technology, RS485 Modbus communication, 4-20mA output, high measurement accuracy, and robust stainless-steel construction.
Overview
The Thermal Gas Mass Flow Meter with Modbus RS485 communication is an advanced flow measurement device engineered for accurate monitoring of gas flow in industrial and commercial applications. Unlike conventional volumetric flow meters, it directly measures mass flow, eliminating the need for external pressure and temperature compensation in most applications. This results in improved accuracy and simplified installation.
Designed for use with compressed air, nitrogen, oxygen, carbon dioxide, biogas, natural gas, and various non-corrosive gases, the meter provides reliable performance across a wide range of operating conditions. It is available in multiple pipe sizes and connection types including threaded, flanged, and insertion configurations to suit different installation requirements.
How It Works
The flow meter utilizes thermal dispersion technology. Two temperature sensors are positioned within the gas stream. One sensor is heated while the other measures the gas temperature. As gas flows past the heated sensor, heat is carried away at a rate proportional to the mass flow velocity. The instrument continuously calculates the gas mass flow based on this heat transfer principle and converts the measurement into flow rate, totalized flow, and other process data.
Measured data can be transmitted to control systems through RS485 Modbus communication and analog 4-20mA outputs, enabling seamless integration into PLC, DCS, SCADA, and remote monitoring platforms.
Why Choose This Product
This thermal gas flow meter offers an ideal combination of accuracy, reliability, and digital connectivity. Its direct mass flow measurement capability eliminates many sources of measurement error found in traditional gas flow measurement technologies. The robust stainless-steel design ensures long-term durability, while Modbus communication simplifies integration into modern automation systems.
