Analysis is made of the effect of the parameters of 
the elements of the vacuum system and the temperature of the water 
vapor on the speed of pumping-out the chamber of a dynamic thermovacuum 
hydrometer. To stabilize the speed of pumping-out the chamber it is 
suggested that a diaphragm be mounted; an expression for calculation 
of the diaphragm cross section is given.
