2. Silicone Button Pads, 
3. Button & Key flexible webbing
4. Button & Key Travel
5. Carbon Pills & Graphite Pads (Conductive Materials)

Silicone Keypads Surface Symbols & Icons
1. Screen Printing
2. Laser Etching (Legends for LED backlight)
3. Embossed & Debossed Molded Symbols

Silicone Keypads Surface Protection
1. Matte Smooth Coating
2. PU Coating
3. Epoxy Coating
4. Silicone Key with Plastic Button Cap
5. Silicone Key with Metal Button Cap

Notes: PU coating is more wearproof, and protective effects is better than matte smooth coating. However, PU coating is more expensive than matte smooth coating.
And also matte smooth coating have good tactile effect, PU coating is not too hard and not good tactile effect. Most silicone rubber keypads choose matte smooth coating.

Portable Ultrasonic Flowmeter

Portable Ultrasonic Flowmeter uses the principle of low voltage, multi-pulse time difference, the use of high-precision and ultra-stable double balance signal differential transmission, differential reception digital detection technology, when the ultrasonic beam propagates in the liquid, the flow of the liquid will make a small change in the propagation time, the change in the propagation time is proportional to the flow rate of the liquid.

At zero flow, the time required for the two sensors to transmit and receive sound waves is exactly the same (the only technology that can actually measure zero flow), and when the liquid flows, the transmission time of sound waves in the countercurrent direction is greater than that in the forward direction.
