1. Control gasometers
1.1 Description
The gasometer is used to calibrate and check gas meters with a maximum flow rate of less than 1,600 m 3 /h. It is only used for calibration in air, at low pressure.
SCROLL TO TOPThe gasometer (figure 1 ) essentially consists of a bell dipped more or less into the liquid in a tank.
