Liquid Turbine Flowmeter Pulse Blind Display Motherboard
This blind display motherboard is specifically designed for liquid turbine flowmeters that do not require an onboard LCD screen. It focuses on high-reliability pulse signal acquisition, signal conversion, and remote data transmission. The board is ideal for OEM applications, embedded systems, or scenarios where flow data is read via external displays, PLCs, or SCADA systems rather than a local screen.

Key Features
