Gas Turbine Flowmeter Motherboard – Dual-Mode for Turbine & Roots Flowmeters
This gas turbine flowmeter motherboard is a versatile signal processing and control unit designed for precision gas flow measurement. It supports a wide range of communication protocols, analog/pulse outputs, and power options — including battery power for remote field operation. A unique feature of this board is its ability to be reconfigured for roots (rotary lobe / 腰轮) flowmeters, providing excellent flexibility for OEMs and end users who work with multiple flowmeter types.

Key Features & Functions
Communication Protocols
RS485 Modbus (standard)
HART protocol (bidirectional communication)
GPRS wireless (in development / available soon)
Analog & Pulse Outputs
4–20mA
1–5V / 2–10V
Frequency output (scalable to flow rate)
Equivalent pulse output (scaled pulse per volume or mass unit)
Power Supply Options
24V DC (standard industrial)
Battery-powered (for remote, off-grid, or field installations)
Flow Compensation
Temperature & pressure (T/P) compensation for density correction and volumetric-to-mass conversion
Hardware & Control Features
Alarm output (high/low flow, temperature, pressure, or fault notification)
Support for split-mounted configuration (optional)
Special Feature – Dual Flowmeter Compatibility
Configurable for gas turbine flowmeter operation
Reconfigurable for roots flowmeter operation — same functions apply

Applications
Natural gas distribution and metering
Industrial gas flow measurement (nitrogen, oxygen, argon, etc.)
Remote wellhead or pipeline monitoring (battery + GPRS)
Roots flowmeter applications for higher viscosity or lower flow rates
Custody transfer and process gas monitoring
