High-Pressure Electromagnetic Flow Meter:
Product Overview:
The high-pressure electromagnetic flow meter consists of a high-pressure electromagnetic flow sensor and a high-pressure electromagnetic flow converter. Manufactured using specialized processes, it is designed to measure the volumetric flow of conductive liquids or liquid-solid two-phase media (e.g., aqueous solutions, slurries, cement pastes, and high-pressure water injection) under high-pressure conditions. It can withstand pressures up to 40MPa, features no obstructive moving parts inside the pipe, almost no pressure loss, and has low requirements for straight pipe sections. Even in harsh environments, its surface corrosion resistance remains exceptional.
Features:
- Corrosion-resistant full stainless steel material and ABS fully molded probe; simple structure.
- Sturdy design with no moving parts, easy maintenance, long service life; no flow-blocking components, resulting in zero pressure loss.
- Strong anti-interference capability; flow measurement is unaffected by changes in fluid density, viscosity, temperature, pressure, or conductivity. The sensor’s induced voltage signal is linearly proportional to the average flow velocity, ensuring high measurement accuracy.
- Suitable not only for general process detection but also for measuring flow of acids, alkalis, salt solutions, slurries, mineral pastes, paper pulp, and similar media.
- Utilizes SMD components and surface-mount technology (SMT), ensuring high circuit reliability.
- On-site adjustable range to better match data acquisition terminals based on user needs.
- Supports digital communication outputs: RS485, RS232, Hart, Modbus, Profibus-DP, etc. (optional).
- Self-checking, self-diagnostic, and alarm functions.
- Ultra-low EMI switching power supply, compatible with wide voltage ranges and excellent EMI resistance.
