DIFMANOMETR DSS-711, DSS-712

Differential manometers (difmanometr) bellows-sealed are intended for measurement:
a) an expense of liquid and gaseous environments by a method of variable difference of pressure (flowmeters);
b) differences of pressure of liquid and gaseous environments (perepadomer);
c) level of the liquid environments which are under atmospheric, vakuummetrichesky or excessive pressure (level gages).

DSS-711 - difmanometr recording with the drive of a chart disk from the electric motor;
DSS-712 - difmanometr recording with the drive of a chart disk from the hour mechanism;
