Product Introduction
The GT300-E remote type electromagnetic flowmeter is a model where the flow sensor and converter are separated and connected by a cable, making it suitable for installation in places with deep piping or harsh environments. It measures flow rate based on the principle of Faraday's law of electromagnetic induction. It can measure fluids with a conductivity of 5 Micro Siemens. or higher, even if solid components are present in the fluid. With no moving parts, it offers excellent durability and a long lifespan, while providing a much larger turndown ratio (100:1) compared to mechanical flowmeters (e.g., turbine meters).
Product Features
- Used across various industries for a wide range of pipelines with diameters from DN10 to 2400mm.
- It offers excellent cost-performance, reproducibility, accuracy, and long-term stability.
- There is no pressure loss as it has no moving parts.
- It is widely applicable to fluids with an electrical conductivity of 5 Micro Siemens or higher.
- Multiple signal outputs: 4–20 mA, Pulse, Alarm
- RS-485 및 Modbus 통신.
Environmental Adaptability: The converter can be separately installed (surface mounted) on a wall or pipe at eye level for convenient maintenance.
Robust Waterproof Performance: When the IP68 rating option is selected for the remote sensor, stable measurement is possible even under fully submerged conditions.
Noise Isolation: Uses a dedicated signal cable to protect data from electromagnetic interference.
Applications
- It is widely used in various industrial fields, such as underground buried pipelines, inside manholes, and high-temperature liquid transfer lines where on-site verification is difficult due to severe vibration or heat.
- Energy & Resources: Petroleum, Electric power
- Chemicals & Manufacturing: Chemical engineering, Papermaking
- Health & Environment: Pharmacology, Environmental protection facilities, etc.
