With the development of intelligent metering, there are many types of water meters. The most common ones on the market are ultrasonic water meters and mechanical water meters. Ultrasonic water meters are more popular now. Today, as an ultrasonic water meter manufacturer, we will talk about the differences between these two water meters from different angles, hoping to help everyone.
1. Water quality requirements
Ultrasonic water meter: not affected by impurities such as gravel and weeds in the medium, chemical substances, and magnetic substances.
Mechanical water meter: water quality similar to tap water must be used, and the liquid must not contain impurities such as rust, gravel, and weeds.
2. Range ratio
Ultrasonic water meter: The range is generally better than 100:1, the starting flow rate is extremely low, which can be lower than 0.01m/s, and the effective measurement range is large, which can avoid running, bubbling, dripping, and leaking.
Mechanical water meter: It is difficult to make high range ratio products, and the range ratio of conventional water meters is generally below 80.
3. Wearability
Ultrasonic water meter: no mechanical moving parts, never wear, accuracy has little to do with the use time, generally the calibration cycle is more than 3 years.
Mechanical water meter: use mechanical rotating parts such as impeller gears to measure, there is wear, the longer the use time, the lower the measurement accuracy.
4. Pressure loss
Ultrasonic water meter: meet the minimum level of pressure loss AP10.
Mechanical water meter: pressure loss is large, around AP63.
5. Protection level
Ultrasonic water meter: electronic products, the protection level strictly reaches IP68 requirements, must be qualified products can achieve.
Mechanical water meter: IP68.
6. Installation requirements
Ultrasonic water meter: industry-leading products can be better than U3D0: upstream requires 3 times the pipe section aperture length, downstream can be directly connected to the elbow.
Mechanical water meter: U10D5: upstream requires 10 times the pipe section aperture length, downstream requires 5 times the pipe section aperture length.
7. Installation method
Ultrasonic water meter: You can freely choose the installation method horizontally, vertically, or tilted according to the site conditions.
Mechanical water meter: Single installation, must be strictly horizontal or vertical.
8. Power supply problem
Ultrasonic water meter: Qualified product, can guarantee a battery life of more than 10 years under a flow measurement cycle of at least 1S.
Mechanical water meter: Mechanical base meter does not require power supply.
9. Communication network
Ultrasonic water meter: Internal circuit initiated, no external electronic device required, zero communication error.
Mechanical water meter: Need to add additional electronic device.
