YFLD electromagnetic flowmeter is an electromagnetic induction type flow measuring instrument, used to measure the volume flow of various conductive liquids. The measured medium includes acid, alkali, salt and other strong corrosive liquids and pulp, mud, mineral pulp, waste water , Seawater and solid-liquid two-phase fluid. The product is mainly used in petrochemical, steel, electric power, metallurgy, textile, food, pharmaceutical, paper and other industries, as well as municipal environmental protection, water conservancy and other fields.
❐Rugged all-metal structure design;
❐ Non-contact magnetic coupling transmission indicator;
❐The measurement system of stainless steel, Hastelloy, titanium and PTFE materials can be selected, which can be suitable for high temperature, high pressure and strong corrosive media;
❐ Low pressure loss design;
❐Short stroke, miniature structure design, total instrument height 250mm;
❐The magnetic coupling structure design ensures more stable signal data transmission;
❐ It can be equipped with thermal insulation or heating jacket structure;
❐The installation method can be divided into vertical and horizontal installation, which can be adapted to various installation occasions;
❐ It is suitable for flow measurement of medium with small diameter and low velocity;
❐The measurement is stable, the work is reliable, the maintenance is small, and the service life is long;
❐ The requirements for straight pipe sections are not high, the first 5DN and the rear 250mm are enough;
❐ Wider flow rate range ratio: 10:1;
❐ Two-line liquid crystal display, on-site instantaneous and cumulative flow display can be selected, with backlight;
❐ It can be used for the measurement of flammable and explosive hazardous environment;
❐ The power supply can choose 24V or lithium battery self-powered type;
❐Multi-parameter intelligent calibration function;
❐ With data recovery, data backup and power failure protection functions;
