The YIDU P series portable gas mass flowmeter, with its advantages of high precision, high repeatability, high stability, fast response, long battery life, and easy operation, can meet the flow measurement and equipment calibration needs of atmospheric operation and maintenance in different scenarios, regions, and environments. As one of the few devices in the industry that can directly measure volumetric flow, it is favored by atmospheric operation and maintenance industry professionals.

The product has a small size and weighs only 567g, making it easy to fit into a pocket or tool kit like a smartphone, enabling measurement anytime, anywhere. Equipped with a high-definition touch screen, it can display real-time key data such as temperature, pressure, volumetric flow rate, mass flow rate, and cumulative flow rate, which is intuitive and convenient, greatly improving work efficiency.

The P series flowmeter can adapt to complex outdoor working environments and easily cope with harsh conditions such as high altitude, low pressure, and low temperature. With precision laminar flow components and pressure sensors, it ensures high measurement accuracy (± 1% Rd), long-term accuracy without drift (± 0.1% F.S.), wide medium temperature range (-20 ℃~60 ℃), wide measurement range (0.5ml~5000L/min), and working pressure up to 2MPa. The product has stable performance and high reliability, making it a trusted professional tool for users.

The application range of the YIDU P series portable gas mass flowmeter is far beyond the field of environmental monitoring. Its high precision, portability, and flexibility make it fully valuable in industrial process control, laboratory and research institute fluid measurement and calibration in fields such as semiconductors, biomedicine, fuel cells, photovoltaics, etc.

The P series quality flowmeter solves the problem of on-site calibration of precision instruments. When measuring equipment needs regular calibration and maintenance, traditional methods require disassembling the flowmeter or flow controller for inspection, resulting in production line downtime for several days. The YIDU P series portable flowmeter can be directly connected to the production line to complete flow calibration without stopping the machine.

The product has over 70 built-in gas databases that support one click switching of gas media on the touch screen without the need for manual conversion factors. This flexibility makes it highly favored. Its laminar differential pressure design principle and characteristics make it a powerful tool for flow calibration, and each unit can be sent to the National Institute of Metrology or local metrology institutes for certification!
