Flow Meter Price China Water Electromagnetic Flow Meter Inline Liquid Flow Meter
Description Flow Meter Price China Water Electromagnetic Flow Meter Inline Liquid Flow Meter
Electromagnetic Flowmeters (EMF for short) is a new type of flow measuring instrument developed rapidly with the development of electronic technology in the 1950s and 1960s. Electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow of conductive fluid according to the electromotive force induced by the conductive fluid passing through an external magnetic field.

Features Flow Meter Price China Water Electromagnetic Flow Meter Inline Liquid Flow Meter
1. The measurement is not affected by changes in fluid density,
viscosity, temperature, pressure and conductivity;
2. There are no obstructing flow parts in the measuring tube, no
pressure loss, and low requirements for straight pipe sections.
Unique adaptability to slurry measurement;
3. Reasonable selection of sensor lining and electrode materials,
that is, good corrosion resistance and wear resistance;
4. The converter adopts a novel excitation method, with low power
consumption, stable zero point and high accuracy. The flow range
can reach 150:1;
5. The converter can be integrated or separated with the sensor;
6. The converter adopts 16-bit high-performance microprocessor,
2x16LCD display, convenient parameter setting and reliable
programming;
7. The flowmeter is a two-way measurement system with three
built-in totalizers: forward total, reverse total and difference
total; it can display forward and reverse flow, and has a variety
of outputs: current, pulse, digital communication , HART;
8. The converter adopts surface mount technology (SMT), with
self-test and self-diagnosis functions;
9. The measurement accuracy is not affected by changes in fluid
density, viscosity, temperature, pressure and conductivity. The
sensor induced voltage signal has a linear relationship with the
average flow rate, so the measurement accuracy is high.
10. There is no obstruction in the measurement pipeline, so there
is no additional pressure loss; there are no moving parts in the
measurement pipeline, so the sensor has a very long life.
11. Since the induced voltage signal is formed in the entire space
filled with magnetic field and is the average value on the pipeline
surface, the straight pipe section required by the sensor is short,
and the length is 5 times the pipe diameter.
12. The converter adopts the latest and most advanced single chip
microcomputer (MCU) and surface mount technology (SMT) in the
world, with reliable performance, high precision, low power
consumption, stable zero point and convenient parameter setting.
Click on the Chinese display LCD to display the cumulative flow,
instantaneous flow, flow rate, flow percentage, etc.
13. Two-way measurement system, which can measure forward flow and
reverse flow. The use of special production technology and
high-quality materials ensures that the performance of the product
remains stable for a long time.
