Features
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.
