MEMS Thermal Gas Flow Meter LCD Display for Compressed Air Nitrogen Oxygen Monit

Product Description

Kindly note that this flow meter measures gas flow under standard conditions, so the unit is NmL/min. "NmL" means standard flow rate.

1.NOTE

This flowmeter is suitable for measuring gases such as air, nitrogen, oxygen, argon, methane, propane, carbon dioxide, helium, and more.

Due to SKU limitations, not all applicable gases and flow ranges are listed. If you need to measure other gases or require a different flow range, please contact us for confirmation.

Please contact customer service before placing an order to confirm the measuring medium, pipe diameter, flow range, and connection size.

Smart LCD Display

Clearly shows real-time flow rate and accumulated flow data, allowing users to read values and operate the device more easily.

Strong Anti-Interference Performance

Professionally tested for enhanced EMI resistance, ensuring stable and reliable operation in complex industrial environments.

MEMS Thermal Sensor with Stainless Steel Port

Equipped with a MEMS thermal sensor and stainless steel port. Dual temperature sensing enables automatic temperature and pressure compensation for accurate mass flow measurement.

Multiple Signal Output Options

Supports RS485 Modbus RTU and 4–20 mA signal output.

4. Applications

Widely used in new energy systems, lithium battery equipment, industrial kilns, photovoltaic manufacturing, semiconductor production, chemical processing, food and beverage production, pharmaceuticals, research laboratories, agriculture, and other related fields.

5. FAQs

Q1: Is this flow meter suitable for corrosive gases?

A1: This flow meter is specially designed for non-corrosive gases such as air, CO₂, N₂, O₂, and Ar. If you need to measure corrosive gases, please contact us for customized solutions.

Q2: Can this device be connected to industrial automation systems?

A2: Yes. The device supports RS485 communication with Modbus RTU protocol as well as 4–20mA output, making it easy to integrate with PLC, SCADA, and other industrial automation systems.

Q3: What is the minimum flow this device can detect?

A3: The minimum detectable flow is ±1 NmL/min, making it highly suitable for micro flow measurement and high-precision flow control applications.
