ATZTA TRX / ATZTA TRZ

Ultrasonic Flow Meter
For Compressed Air and Nitrogen

A new flow meter with a new function (RS485 Output) has been added to the popular lineup of the TRX/TRZ series. It helps you save energy by measuring and “visualizing” flow rate, temperature and pressure.

ATZTA TRX

Ultrasonic Flow Meters
For Compressed Air and Nitrogen (Diameters 40A, 50A, 65A, and 80A)

A cost effective ultrasonic flow meter specialized for measuring air and nitrogen is now available!

It has realized a wide range of measuring ability and ZERO pressure loss using the characteristics of ultrasonic waves. It is also well-equipped to handle dust and mist and has excellent durability compared with conventional flow meters that use other measuring principles because it does not have moving parts.

The meter can be selected from two types of power sources: built-in batteries that can run 10 years without needing power construction, or an external power supply (24 VDC).

・To understand and visualize the usage of compressed air as a measure of saving electric power.. ・To understand the amount of nitrogen refined and used in a factory. (Can be applied to a degreasing treatment.)

AS-W

Ultrasonic Flow Meter
For Fuel Gas

Since AS-W flow meter covers wider range from small to large flow rate, it contributes to cost saving and convenient facility management. At the same time, it saves the cost of redundant governor and piping.

・ Non-moving parts results in not degrading meter performance. It eventually makes needless to repair the parts and refuel the lubricant oil.
・ Because of the pressure loss being closely “0”, it can get rid of the pressure shortage risk.
・ Because of lightweight and compact feature, it enables easy installation and needs less space.

AS-WE

Ultrasonic Flow Meter
For Fuel Gas (CE-marked version)

ATZTA TBZ / ATZTA TBX

Turbine Gas Meters
for Flow Management

Turbine meters in the TBZ and TBX series were developed for controlling the gas consumption of each piece of equipment such as compact boilers and various industrial furnaces.

The products realize a smart design with a lightweight and compact body and support a wide range of measurement including maximum working pressure and maximum measuring flow rate.

Furthermore, the built-in 2-system pulse transmitters enable you to establish a remote meter reading system and an energy control system.

The TBZ series even corrects temperature and pressure to allow you to read gas consumption in the standard conversion condition.

The external power supply model TBX-D has been newly added to the lineup of the TBX series. You can choose the model that would best suit your applications for better usability.

Note) TBX30, TBX100, and TBX100F are CE compliant. (Collaborative development product with Tokyo Gas Co., Ltd.)

ATZTA UX

Ultrasonic Flow Meter
For Fuel Gas Control

A new product has been added to the lineup of ultrasonic flow meters for fuel gas! It realizes a wide range of measuring ability that includes microflows using the characteristics of ultrasonic waves. It is resistant to dust so there is no need to install filters. The flow meters are perfect for low flow gas measurement such as food and controlling gas usage of small-scale furnaces. (Collaborative development product with Tokyo Gas Co., Ltd.)

・High performance that supports a wide range of flow rate.

Realizes a wide range of 1:50, covering minimum to maximum flow rates.

・Dust resistant and highly durable

No need to install filters.

・Space-saving, as it requires no straight piping.

Measures with a high degree of accuracy even installed immediately after elbow piping.

・You have a choice of driving power supply.

Select from AC power, DC power and built-in batteries.

・A variety of output functions support visualizing flows.

Unit pulse/ 4 – 20 mA DC/ RS485 (Modbus/RTU)*

* RS485 is only for the AC or DC power models.

ATZTA UX / ATZTA UZ

Ultrasonic Flow Meter
For Fuel Gas Control

No straight pipe section required for installation

It is possible to connect the flow meter directly to a bend such as an elbow piece and a flexible pipe.

As wide as a 1:50 turn down ratio

Applicable also for measuring gas flow of a burner having a large turn down ratio.

Easy to replace batteries

Users can replace batteries without removing the meter from the piping.

Strong against dust, and high durability

Use the product in such a condition that does not allow the gas to re-liquefy into oil mist.

IP64 Protection – available for outdoor use

High temperature can cause the electronic circuit board to be deteriorated and batteries to be consumed. To avoid unnecessary rise in temperature, the product is recommended to be fitted with a sunshade.
