Mr. TríFeatures
A cost effective ultrasonic flow meter specialized for measuring air 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 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.

*1:In the actual flow measurement setting, the digits of the accumulated flow rate display, instantaneous flow rate display and pulse output vary.
*2: When displaying the instantaneous flow (NL /min), the main display (accumulated flow rate), sub-display (instantaneous flow rate [Nm3/h]), pressure (kPa) and temperature (°C) will not be displayed.
* Piping conditions:
20D or higher in upstream and 5D or higher in downstream for the 25A/32A models. (When using in the forward and reverse display mode, 20D or higher on both sides.)
