Paper pulp electromagnetic Flow Meter
The application of electromagnetic flowmeter in pulp is mainly reflected in flow measurement
and control, which plays an important role in the papermaking industry.
Application background and measurement principle
Electromagnetic flowmeter works based on the principle of electromagnetic induction.
When a conductive liquid (such as pulp) flows in a magnetic field, it cuts the magnetic
lines and generates an induced electromotive force. By measuring the magnitude of this
induced electromotive force, the flow rate of the fluid can be inferred. The electromagnetic
flowmeter consists of a transmitter and a converter. The transmitter generates a magnetic
field and measures the induced electromotive force, and the converter converts the signal
into a flow value.
Specific application in pulp flow measurement
In the papermaking industry, electromagnetic flowmeters are widely used in the measurement
and control of pulp flow. Specific applications include:
1. Pulping process: used to measure the flow of fluids such as pulping, water and acid or
alkali to ensure the quality and production efficiency of pulp
2. Papermaking process: used to monitor the flow of additives such as cooling water,
alum, talcum powder, and measure the flow of different types of pulp, and participate
in the pulping process to obtain the required quality of paper
3. Sewage treatment: used to measure the flow of sewage and wastewater to ensure
the effective operation of the treatment system and reduce the impact on the environment
Advantages and features
Electromagnetic flowmeter has a It has the following advantages:
1. Accurate measurement: It is not affected by physical properties such as fluid density
, viscosity, temperature, etc., and is suitable for measuring a variety of fluids.
2. Strong corrosion resistance: It is made of corrosion-resistant materials and is suitable
for corrosive fluids in the papermaking industry.
3. Simple structure: Easy maintenance and reduced use costs.
4. High precision: High measurement accuracy, up to 0.5% to ±1%.
Successful cases and future development trends
With the continuous development of technology, the application prospects of electromagnetic
flowmeters in the papermaking industry will be broader. By real-time monitoring and precise
control of pulp flow, electromagnetic flowmeters help improve production efficiency, reduce
costs and ensure product quality.
