Inline Thermal Mass Flow Meter

The BT-3020-V Inline thermal mass flow meter with thread connection is designed to measure the flow of Air, Natural gas, LPG Gas, Biogas, Flue Flare Gas, etc., for small pipes ranging from ½” up to 2”.

Air, Oxygen Gas, Natural gas, LPG Gas, Biogas, Flue & Flare Gas Sensor : SS 316 / Hastelloy C276 Size: DN 20 to DN 200 Flange: ANSI B16.5, 150# / 300# 4-20mA HART, Pulse & RS 485 Modbus RTU Power Supply: 24 VDC / 230 VAC Temp: 0 ... +150°C

Product Description

The BT-3020-G Inline thermal mass flow meter, equipped with a dual platinum wire wound sensor encapsulated in a 316 Stainless Steel sheath, represents an innovative approach to measuring gas flow rates with exceptional accuracy. This specialized meter utilizes a unique sensor design, employing dual platinum wire coils around a support structure. These coils serve as both heating and temperature-sensing elements.
 

This flow meter is available in both integral and remote transmitter versions. The transmitter unit has a graphical LCD, offering real-time flow data, cumulative values, velocity (nm/s), and process gas temperature. Moreover, it includes 4-20mA HART, RS485, and pulse interfaces, enhancing its connectivity and communication capabilities. It has a dual power input source of 24 VDC and 230VAC. The transmitter comes in flame-proof enclosures, ensuring the safety of personnel, equipment, and the surrounding environment in hazardous areas.
 

The BT-3020-V Inline thermal mass flow meter comes with an inbuilt diagnostic feature that serves as an intelligent system that continuously monitors, analyzes, and reports the health and performance of the meter itself. This feature goes beyond mere flow measurement by providing valuable insights into the meter's functionality, ensuring reliability, accuracy, and early detection of potential issues.
 

The meter employs screwed connections for its installation and integration into piping systems, ensuring a secure and reliable attachment. The screwed connection mechanism involves threads on both the meter and the piping system, allowing for a firm and leak-proof attachment. These connections often use standardized thread types such as NPT (National Pipe Thread) or BSP (British Standard Pipe), ensuring compatibility and ease of installation in various industrial settings.
 

The BT-3020-V is meticulously engineered to accurately measure the flow rate of clean gases like Air, Natural gas, LPG Gas, Biogas, Flue Flare Gas, etc. This versatility makes it indispensable across industries reliant on precise gas control and management for diverse applications.
