The ATZTA AS-W Series from Aichi Tokei are Ultrasonic Flow Meters for Fuel Gas. They are covering a wider range from small to large flow rates than roots meters and turbine meters, contributing to accurate measurement, cost saving and convenient facility management. The structure of measurement portion is very simple with only 2 ultrasonic sensors.
Measurement without mechanical moving part has various advantaged features as high durability against oil, mist and dust and high accuracy without changes over a long period of time. The measurement method makes the series maintenance-free, repair of parts and periodical refuel of lubricant oil are not required. The 1: 400 wide rangeability enables the devices to adapt to various users’ applications under wide changes in flow volume. The lightweight and compact design can achieve more space-saving installation than diaphragm type gas meter.
