Abstract

In order to enable monitoring of operating conditions of a plurality of uniaxial eccentric screw pumps with monitoring means installed in a remote site, a remote monitoring system (1) is capable of sending and receiving operating condition detection information items in a communication network (N) established by wireless intercommunication means (10) provided in the uniaxial eccentric screw pumps (100). Further, the operating condition detection information items aggregated to a coordinator (10a) can be sent to the Internet via Internet connection means (30). By this means, a state is achieved in which the operating conditions of the uniaxial eccentric screw pumps (100) can be monitored by monitoring means (50) connected to the Internet.
