A brief introduction to the explosion-proof flowmeter

Date:2019-12-03 source:

Explosion-proof micro-flowmeter, explosion-proof flowmeter adopts unique double uP technology, high-speed sampling and adaptive signal processing technology, and transmits data to PC through FluxData software to intuitively analyze the measurement results and data management.

Explosion-proof micro-flowmeter

A brief introduction to the explosion-proof flowmeter

Measuring principle

Explosion-proof electromagnetic flowmeter is based on Faraday's law of electromagnetic induction, is composed of sensors and switches, sensors installed on the measuring pipe, the converter can be connected to the sensor combination together referred to as electromagnetic flowmeter, a size converter is installed within 100 meters of within 30 meters away from the sensor or occasions, by shielding cable connection between called separation type electromagnetic flowmeter.When the ultrasonic beam propagates in the liquid, the flow of the liquid will cause a slight change in the propagation time, which is proportional to the velocity of the liquid.

use

It is mainly used to measure volume flow of conductive liquid and slurry in closed pipes.Such as water, sewage, mud, pulp, various acid, alkali, salt solution, food slurry, explosion-proof electromagnetic flowmeter is widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper and other industries as well as environmental protection, municipal management, water conservancy construction and other fields.

Using the environment

-- ambient temperature: -5℃ ~ 40℃;-- the altitude shall not exceed 2000m;-- the relative humidity of the air shall not be greater than 95% (at 25℃);-- in places where there is danger of gas and coal dust explosion;-- in places where corrosive gas or steam without damaging the insulation;Where there is no significant vibration or impact;-- pollution level 3;

advantages

The explosion-proof electromagnetic flowmeter USES constant current low-frequency three-value rectangular wave or double-frequency rectangular wave excitation, with rectangular wave magnetic field, to overcome the sinusoidal wave magnetic field, can eliminate the error caused by power supply voltage fluctuation, power supply frequency change and excitation coil impedance change;?It has excellent zero point stability and is not affected by fluid noise.Thus has the high stability, the high reliability characteristic.
