Product Introduction
The GT-NFM partially filled pipe electromagnetic flowmeter is a state-of-the-art flow measurement solution that can continuously and accurately measure flow even in a partially filled pipe state where the pipe is not completely full of liquid. Unlike typical electromagnetic flowmeters, this product utilizes the Velocity Area Method. It calculates the real-time cross-sectional area with a built-in level sensor and detects the speed of the flow with a velocity sensor, combining these measurements to yield precise flow values at any liquid level.
Product Features
Real-Time Monitoring: Measures and displays instantaneous flow rate, velocity, and totalized flow data in real time.
Easy Intelligent Configuration: Simply by entering the inner diameter of a circular pipe or the width of a rectangular channel, the device automatically calculates and outputs the flow rate within the pipe.
Precise Measurement System: Composed of a high-performance velocity sensor, level sensor, and flow indicator as a set, it provides accurate data regardless of the liquid height.
Applications
t is ideally utilized in any open channel or piping environment where water flows without filling the pipe completely or where gravity discharge occurs. It is particularly essential in various industrial and environmental management sectors as follows:
Urban Infrastructure: Sewage and stormwater drainage pipe monitoring, urban drainage systems.
Water Resource Management: River and natural flow measurement, irrigation and agricultural water channels.
Industry & Environment: Factory wastewater and effluent monitoring, influent/effluent measurement in water treatment facilities.
