Smart electronics - Long battery life - Stable and accurate

Compact PCB design - Working with linear signal increase - Low energy consumption - Stable and reliable - Small and light

Inner PCB

Compare with Landis+Gyr product 1

Strong battery -Integrated with up to 3 high capacity batteries -Optimized electronics lead to lower consumption -Running up to 25 years, without changing battery

Multiple PCB Inner PCB, outer PCB, and extend PCB Make the gas meter safer and multifunctional

2

Elaborate flow duct - Safe and reliable - Small and light

Safer flow duct - Linear signal variation - Low pressure drop - Stiff and rigid - Air leakproof - Dust proof - Small and safe

Flow connector - Round shape inside Give low pressure drop - Different connectors For different applications

3

Innovative

4

- Install transducer from the side - Transducer connect with PCB directly - A motor valve work as a switch - Seal the gas meter - By high temperature silicon - Mirror duct concept leads to smaller

Tiny transducer - Tiny and cheap - Developed for various gas

Cheaper than ever before

- Excellent performance - Tiny and simple - Cheap and easy to make - Carefully chosen material

5

Excellent performance - Developed for gas flow application - Tested with several hundred transducer - Manufacture easier - Tested in multiple shapes, thickness, wires, components, and materials.

6

Other manufactures’ transducer

CPD transducer

Strong signal - Efficient mode shape at working frequency - Much stronger signal even with dumping - Optimized signal with soldered PCB board - As simple and cheap as possible without lower performance

7

Chemical tolerance - Tested material: PMMA, POM, Rubber, epoxy-resin (el30, tg24, USA) , and other manufactures’ transducer - Method: Hang in the vapor and dip in the liquid - The test was running at least for 3 weeks - They were tested in different flammable chemical substances

8

Easy-to-use Design - Easy for installation - Attractive art design

Chemical tolerance - Flat cover design, easier and cheaper to produce - The transparency part helps IR sensor fix at the right position - Easy to change and fit to different gas meter size - Put 2-3 batteries at the bottom of the box - The left part keeps a port to connect to extension part - It can be open from the side 9

The most simple design - A Simple design can fit to different environment - Open design, easier to extend the functionality - It derives several possible designs, which could fit to customer perspective

10

Concept design - We organized several workshops to get the right direction of the design - From a very board view, we have inferred out the special enclosure design - Final design can fit both to functionality of a gas meter and to Visual Identity of specific company

11

Cheap and functional design

12

- Reduce the size of the product could lead to several aspects cheaper: Production cheaper, lower shipping cost, and lower tax and insurance for customer.

- The enclosure design allow authoritative people open the product to change components, to program, and to connect an extend board.

To remember This Ultrasonic Gas Meter is: - Easy for installation - Long battery life - Small and Light - Developed for varied gas - Stable, safe and reliable - Cheaper than ever before - With attractive design
