4-20ma Flow Meter
The 4-20mA flow meter is a widely adopted industrial solution for accurate and reliable flow measurement across various sectors including water treatment, chemical processing, food and beverage, and energy. Known for its stable signal output and compatibility with most PLC and SCADA systems, this type of flow meter ensures seamless integration into existing control frameworks. For procurement professionals focused on system stability, the 4-20mA output provides noise immunity over long cable distances, making it ideal for remote or large-scale installations. Additionally, this flow meter type supports both continuous and batch processes, helping industries to monitor consumption trends, detect anomalies, and ensure process control compliance. For bulk purchasers, standardization on 4-20mA interfaces reduces maintenance complexity across distributed systems and lowers training costs. Whether your application requires inline, insertion, or clamp-on styles, most 4-20mA flow meters are available in a wide range of diameters and materials including stainless steel, PVC, and PTFE-lined variants. Distributors and system integrators benefit from models that offer optional temperature and pressure compensation modules, multilingual LCD displays, and digital diagnostics. A high-quality 4-20mA flow meter offers long service life, minimal calibration drift, and the ability to scale deployment across multiple locations with minimal engineering changes.
Overview
The 4-20mA flow meter, as a type of electromagnetic flow meter, is one of the most widely used industrial instruments for liquid and gas flow measurement. By outputting a standard 4-20mA current signal, it ensures stable, interference-resistant transmission over long distances—ideal for factories, chemical plants, water treatment facilities, and energy sectors that demand real-time process monitoring and seamless PLC/DCS integration.
Gallop provides high-accuracy 4-20mA flow meters engineered for bulk industrial procurement. Whether you need ultrasonic, electromagnetic, turbine, vortex, or differential pressure types, our solutions deliver precision, durability, and cost-efficiency for large-scale operations.
