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. |
