lized a straight pipe section, which is basically equivalent to a water pipe, and does not cause internal blockage.2. Wear contrast: Ordinary mechanical non-magnetic water meter with hard alloy shaft and red stone bearings can wear 2-3 years. There is no moving parts inside the ultrasonic water meter measurement section, so there is no wear.3. Measurement accuracy comparison: ordinary mechanical water meter over time, internal parts will be slowly perishing, the longer the time, the worse the me
