Features Dead Weight Tester Pressure Gauge Calibration Floating Ball Type
1. Float ball pressure meter is built-in automatic flow regulator, after any increase or decrease in weight without further operation, then can output precise pressure.
2. The floating ball does not drop when working, can continuously and stably accurate output pressure signal.
3. Floating ball pressure meter with self-adjusting function.
4. When the instrument is working, the gas flow make the ball suspend in nozzle, the ball is non-contact with the nozzle. Friction is small, reproducible, high resolution, and eliminates the need for rotating weight.
5. In working process, the airflow can constantly clean the float ball, to ensure high reliability of the instrument.
