What is a small flow electromagnetic flowmeter?

Author: Released at: 03:39-11:15 Source: Shanghai Cixi View: 432
?????? Small flow electromagnetic flowmeter According to Faraday's law of electromagnetic induction, it is an inductive instrument to measure the volume flow of conductive medium in the pipe. It adopts the embedded technology of single chip microcomputer to realize digital excitation. At the same time, it adopts can field bus on small liquid flowmeter, which is the first in China, and its technology reaches the leading level in China.
?????? Small liquid flowmeter At the same time, it can output 4 ~ 20mA current signal for recording, regulating and controlling. It has been widely used in chemical industry, environmental protection, metallurgy, medicine, papermaking, water supply and drainage and other industrial technology and management departments.
?????? Small liquid flowmeter In addition to measuring the flow rate of general conductive liquid, it can also measure the volume flow of liquid-solid two-phase flow, high viscosity liquid flow and salt, strong acid and strong alkali liquid.
Performance characteristics ??????????????????????????????? ?
The instrument has simple and reliable structure, no movable parts and long working life.
There is no blocking part, pressure loss and fluid blockage.
No mechanical inertia, fast response and good stability, which can be used in automatic detection, adjustment and program control system.
The measurement accuracy is not affected by the type of measured medium and its physical parameters such as temperature, viscosity, density and pressure.
Different combinations of PTFE or rubber lining and electrode materials such as HC, Hb, 316L and Ti can meet the needs of different media.
There are many kinds of flowmeter models, such as pipeline type and plug-in type.
The EEPROM memory is used to store and protect the measurement data safely and reliably.
There are two types of integration and separation.
High Definition LCD backlight display.
