Electronic turbine gas meter

Electronic turbine gas meter

Features

Wide measuring range and high accuracy It has a wide flow rate measuring range and has high measuring accuracy far precise than the calibration tolerance specified in the Measurement Law of Japan.
Highly accurate calculation Highly accurate calculation can be made by accurate pressure sensor, temperature sensor and microcomputer.
Possible to read both temperature and pressure In addition to the temperature compensation calculated value, it displays the integrated value of non-compensation, temperature compensation, pressure compensation, and temperature and pressure value.
Battery driven type It can be used without changing built-in battery for seven years, and the power supply work is not required.
