DescriptionThe BT-3010-G Inline Thermal Mass Flow Meter uses an advanced thermal dispersion sensor to deliver high accuracy, repeatability, and stable gas flow measurement. It is ideal for monitoring and controlling gas flow in pipelines and industrial process systems.

Its flange connection ensures secure installation with minimal pipeline modification. The inline design provides smooth integration and accurate readings without pressure loss. Built with SS316 industrial-grade materials, it is engineered for harsh environments and long-term reliability.

The meter offers multiple output options, including 4-20 mA and RS485 Modbus RTU, ensuring easy integration with plant control systems. It features self-diagnostics, detecting performance issues and reducing maintenance needs.

With PESO-certified flameproof and weatherproof housing, it is suitable for demanding industries such as oil and gas, chemical plants, energy, and utilities.
