Marine Flow Gauge
Marine Flow Gauge is a marine instrument used for displaying and monitoring liquid flow conditions in ship piping systems.
Designed for marine applications, the flow gauge provides operators with a clear visual indication of flow status, helping monitor fuel, oil, water, and other liquid circulation systems onboard vessels.
Unlike a complete flow meter that calculates and records flow quantity, Marine Flow Gauge mainly focuses on flow indication and system monitoring. It is often installed with flow meters or directly integrated into marine pipeline systems.
Marine Flow Gauge is commonly used in:
Marine fuel systems
Diesel engine systems
Lubrication oil systems
Cooling water systems
Hydraulic systems
Auxiliary ship systems
Overview
Working Principle of Marine Flow Gauge
Marine Flow Gauge displays flow conditions by detecting and indicating the movement of fluid inside the pipeline.
According to different structures, the working principle varies:
| Type | Working Principle |
|---|---|
| Mechanical Flow Gauge | Indicates flow through internal mechanical movement |
| Sight Flow Gauge | Allows direct visual observation of liquid movement |
| Digital Flow Gauge | Displays flow data through electronic signals |
| Pointer Flow Gauge | Shows flow value through dial indication |
