Hydrogen flow meter research and development
We will introduce the ultrasonic flow meter for hydrogen and ultrasonic gas flow sensor currently under research and development.
In recent years, realizing a carbon-neutral society has become an urgent priority in order to achieve the SDGs. In this context, hydrogen has been attracting attention as a clean energy resource that does not emit carbon dioxide. With an eye on the future hydrogen society, we have been one of the first to undertake research into applying ultrasonic city gas and LP gas flow measurement technology to hydrogen.
> Introducing the latest technology｜Research and development “Measuring hydrogen flow using ultrasound”
Currently, the following initiatives are underway in new areas where hydrogen can be utilized:
– Under the government’s hydrogen introduction support measures, large-scale hydrogen use in port areas is being considered.
– Promoting a “local production, local consumption” model that uses water electrolysis equipment to produce and consume hydrogen locally.
– In the industrial sector, efforts are being made to switch industrial furnaces and boilers to carbon-free fuels such as hydrogen.
In order to meet the diverse needs for measuring hydrogen flow rates, we are developing unprecedented large-flow hydrogen flow measurement technology.We are also continuously investigating and researching new methods of flow measurement that will be required in a hydrogen society.
Here, we will introduce the “hydrogen ultrasonic flow meter” and “ultrasonic gas flow sensor” that are currently under development.

Ultrasonic Flow Meter For Hydrogen gasModel: ATZTA HU120 (tentative name)
Jointly developed product by Tokyo Gas Co., Ltd. and Tokyo Gas Engineering Solutions Co., Ltd.
Enables visualization and management of hydrogen gas flow rate
Based on the technology cultivated in ultrasonic flow meters for fuel gas, we have built an ultrasonic measurement unit specialized for hydrogen flow measurement.
This makes it possible to visualize and manage hydrogen gas flow rates not only in fuel cells but also in a variety of applications, including the combustion equipment market and hydrogen production market.

Features
“Low Pressure Drop”
Low pressure drop allows for use in piping after pressure reduction or when the hydrogen supply pressure is low.
“No Straight Pipe Sections Required”
Since no straight pipe sections are required before or after the flowmeter, it can be directly connected to elbows or other bent pipes or flexible pipes, thereby saving space in piping.
“Proven Durability”
Long-term demonstration experiments using hydrogen have proven the high durability of the ultrasonic measuring unit. Outdoor installation is also possible.
“Wet Hydrogen Flow Measurement”
It is possible to measure the flow rate of hydrogen containing moisture.
Even if water accumulates in the flow path, it can be used without malfunction as long as it is properly drained.

Ultrasonic Gas Flow SensorModel: ATZTA HB06 (tentative name)
Slim Ultrasonic Gas Flow Sensor
Anticipating demand for hydrogen flow measurement for purposes other than fuel gas, we are currently developing a gas flow sensor for small flow rates.
Its slim shape, unlike anything we have seen in our previous lineup, allows for neat piping setup and we are aiming for a product that is also suitable for integration into various devices such as water electrolysis equipment.

Features
“Slim and Simple”
The distinctive pipe-like exterior incorporates minimal but sufficient functionality.
“Low Pressure Drop”
The low pressure drop allows for reliable use even in applications with low gas supply pressure.
“Wet Gas Flow Measurement”
It can measure the flow rate of hydrogen and oxygen containing moisture.
Even if water accumulates in the flow path, it can be used without malfunction by properly draining it.
“Compatible with Various Gas Flow Measurements”
It can measure the volumetric flow rate of hydrogen and oxygen regardless of the mixture ratio, and compatibility with other gases is also under consideration.
