Configuration
The Series 9000MP Multipoint System includes one or more Series 9000MP Probes and a Series 9600MP System Control Panel. The 9000MP flow transmitter probe assembly is the heart of the system. The probe assembly typically has two or more flow sensors mounted in a 1½” OD probe shaft. The 9000MP probe’s sensors are removable for field replacement if one is damaged. Each sensor is matched to its own bridge board and microprocessor to function, in effect, as a complete flow meter. The linearized output signals from the multiple sensor assemblies in each probe are averaged to create one overall probe output signal.
