Electromagnetic flowmeter is the first choice: 1, the requirements of straight pipe section is relatively low, generally the first three and the second can be; 2, whether you are municipal sewage or factory wastewater, electromagnetic has a corresponding lining and electrodes, long service life, and stable; 3, from the accuracy point of view, the electromagnetic flowmeter quality clearance, calibration qualified, level 0.5 is no problem, vortex flowmeter in the actual use of 1.5-2 level is very good. For everyone to say the vibration, it is really fatal to the vortex street, because the principle of the vortex street itself is the Karman vortex phenomenon, the vibration changes the fluid distribution, and the Karman vortex phenomenon is disturbed. In addition, since it is sewage, there must be dirt inside. If there is floc, high adhesion, it is even more terrible, attached to the vibrator, although it will not endanger the service life, but the accuracy is not guaranteed.

Applications: ultrasonic vibration tranducer for inkjet printer
Vibration mechanism of inkjet printer:
Generally, it is composed of piezoelectric ceramics and driving rods. By high-frequency electric excitation, piezo ceramics produce high-frequency ultrasonic vibration (above 60 kHz or higher), which is transmitted to the driving rod and generates high-frequency micro-displacement (back and forth expansion) at its front end.
Piezo ceramics components features :
1. High vibration amplitude and can withstand higher power.
2. The product has high reliability, strong maintainability, and is not easy to break down or off-line.
3. The frequency can be adjusted in a wide range, generally within the range of 10KHz.
