The difference between a water meter and a flowmeter
Qualitatively, the general electromagnetic flowmeter is good, followed by water meters, while the ultrasonic difference
The accuracy of electromagnetic flowmeter is high, generally can reach 0.5, ultrasonic flowmeter next, generally 1, and mechanical water meter accuracy is poor
Measuring medium, mechanical water meters are generally only measured tap water, electromagnetic flowmeter measuring medium must be conductive, and ultrasonic measurement range
The installation and maintenance of ultrasonic flowmeter is convenient, no process parking, and the other two are parking to install
