Product Description

Piezoelectric ceramic disc For flowmeter

Quick delivery, Stable performance,wrapped around electrode on request, high consistance.

There are two main types of ultrasonic flow meters: Doppler and transit time. While they both utilize ultrasound to make measurements and can be non-invasive (measure flow from outside the tube, pipe or vessel). Various kinds of ultrasonic flowmeters have been widely used in industrial production, commercial measurement and hydraulic testing.

Diameter: 5-100mm

Frequency: 200KHz- 10MHz
