Liquid Turbine Flowmeter Motherboard – Dual-Function for Turbine & Oval Gear
This liquid turbine flowmeter motherboard is a high-performance signal processing and control unit designed for precision liquid flow measurement. It supports a wide range of communication protocols, output types, and power options. With its unique reconfigurable design, the same board can be adjusted to work with oval gear flowmeters, providing excellent flexibility for inventory management and OEM applications.
