Ultra-High Pressure Electromagnetic Flowmeter (25–42 MPa)
Overview
This electromagnetic flowmeter is specifically developed for high-pressure liquid measurement in oilfield applications, including polymer mother liquor, chemical injection, and pulsating flow from plunger pumps. It delivers stable, accurate measurement with a long service life, making it ideal for petrochemical, water injection, and chemical dosing systems.
Key Features
Accurate low-flow measurement – starts measuring reliably from 0.01 m³/h
Suitable for harsh media – handles liquids with particles, slurries, mud, and chemical agents
High-pressure capability – pressure ratings from 25 MPa to 42 MPa
Strong anti-interference – resistant to static and lightning surge voltages up to 1500 V
Multiple material options – electrodes available in 316L SS, Hastelloy C, Titanium, and more
Flexible installation – available in compact or remote versions
