Description

Rotor gas meters of CGR-01 are intended for measurement of volume of the proceeding gas. In standard execution they can work at types of the gases specified in Table 1 with a working pressure to pmax = 1,6 MPa.

PRINCIPLE OF OPERATION OF THE ROTOR COUNTER

Rotor schetkik is the device of cyclic action. One cycle of work comes to the end for turn of rotors on a corner 360 °. To its current there is a movement of 4 portions of gas (on 2 on each rotor). The volume of one transported portion of gas is approximately equal to the volume of a measuring chamber which is space between a rotor and a wall of the case of the counter. The proceeding gas fills chambers and sets rotors in rotation motion. Summation of the leaked volume of gas happens on the basis of quantity of the executed work cycles.
