Product details
1、 Product Overview
Electromagnetic flowmeter is a flowmeter based on Faraday's law of electromagnetic induction to measure flow rate. It is widely used in industrial fields such as chemical fiber, food, papermaking, sugar production, mining and metallurgy, water supply and drainage, environmental protection, water conservancy engineering, steel, petroleum, pharmaceuticals, etc. It is used to measure the volume flow rate of various acid and alkali, salt solution, slurry, pulp, coal water slurry, corn slurry, fiber slurry, grain slurry, lime slurry, sewage, cooling raw water, water supply and drainage, salt water, hydrogen peroxide, beer, wort, various beverages, black liquor, green liquid and other conductive liquid media.
IIProduct Features:
l There are no movable parts or flow blocking components inside the pipeline, and there is almost no additional pressure loss during measurement.
l The measurement results are independent of physical parameters such as flow velocity distribution, fluid pressure, temperature, density, viscosity, etc.
l On site, the range can be modified online according to the actual needs of the user.
l High definition backlightLCD display, fully Chinese menu operation, easy to use, simple to operate, easy to learn and understand.
l adoptSMD devices and surface mount technology (SMT circuits have high reliability).
l adopt32-bit high-performance microprocessor has fast computing speed, high accuracy, programmable low-frequency rectangular wave excitation, improved stability of flow measurement, and low power consumption.
l All digital processing, strong anti-interference ability, reliable measurement, high accuracy, and a flow measurement range of up to150:1
l ultra-lowEMI switching power supply, suitable for a wide range of power supply voltage changes, with good EMC performance
l There are three integrators inside that can display the forward cumulative amount, reverse cumulative amount, and differential cumulative amount respectively. There is also a non power-off clock inside,
l recordable16 power outage times
l haveRS485, RS232, Hart, Modbus and other digital communication signal outputs are optional.
l Equipped with self checking and self diagnostic functions
