Ultrasonic flowmeter and electromagnetic flowmeter are common industrial flow measurement equipment, each of which has different characteristics and application fields.
Ultrasonic flowmeter:
Features:
1. Non-invasive, no pressure loss;
2. Easy installation, low maintenance cost;
3. Wide measuring range, can measure high temperature, high viscosity liquid and gas;
4. The flow path design is flexible and suitable for various scenarios and pipe diameters.
The difference:
1. Measurement principle: Ultrasonic flowmeter uses ultrasonic technology to measure the flow rate, transmits ultrasonic wave to the medium to be measured through the sensor, and then receives the rebound signal, calculates the flow rate according to the propagation speed of ultrasonic wave in the medium; The electromagnetic flowmeter uses Faraday’s law to measure the magnetic field induction of moving charged particles in conductive media.
2. Different conditions by environmental interference: because ultrasonic flowmeters need to send and receive ultrasonic signals, they are greatly affected by external factors such as noise and noise, and are more susceptible to environmental interference than electromagnetic flowmeters.
Electromagnetic flowmeter:
Features:
1. High accuracy, good long-term measurement stability;
2. Non-occlusive, no moving parts, and high reliability;
3. Wide application range, can measure conductive liquid.
The differences:
1. Measurement principle: As mentioned above, electromagnetic flowmeter is the use of electrically charged particles in the conductive medium induced by the external magnetic field force to oscillate and change the electrical signal to obtain real-time flow data.
2. Different conditions by environmental interference: Because electromagnetic waves will have a certain impact on electromagnetic flowmeters, the use effect is easy to be limited under harsh sites or complex process conditions such as medium frequency transmission radiation and strong light in Asia
