UXHigh Performance Ultrasonic Flow Meters for Fuel Gas
Features
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.
