Section Introduction MANUAL SCOPE The Series 8700 Magnetic Flowmeter System combines a Rosemount magnetic flowmeter flowtube and Rosemount magnetic flowmeter transmitter. This manual covers the Model 8712C/U/H Magnetic Flowmeter Transmitter. For specific magnetic flowtube information, refer to the Series 8700 Magnetic Flowmeter Flowtubes manual (document number 00809-0100-4727).
Model 8712C/U/H Magnetic Flowmeter Transmitters SYSTEM DESCRIPTION A Rosemount Series 8700 Magnetic Flowmeter System measures volumetric flow rate by detecting the velocity of a conductive liquid that passes through a magnetic field. The system consists of two major assemblies: the Model 8705, the Model 8707 High-Signal, or Model 8711 Magnetic Flowmeter Flowtube combined with a magnetic flowmeter transmitter.
FM or CSA approval. Do not connect a Model 8712C/U/H to a non-Rosemount flowtube that is located in an explosive atmosphere. Failure to comply could result in an electrical spark or an explosion.
(see Figure 2-1). The transmitter should be mounted in an upright position. If the Model 8712C/U/H is mounted separately from the flowtube, it is not subject to limitations that might apply to the flowtube. For considerations regarding the installation of the flowtube, please refer to the flowtube manual (document number 00809-0100-4727).
Pipe Mounting To mount the transmitter on a pipe: 1. Attach the mounting plate to the pipe using the mounting hardware. 2. Attach the Model 8712C/U/H to the mounting plate using the mounting screws. Surface Mounting To surface mount the transmitter: 1.

Supply Current versus Input Voltage Surge Nominal Input Voltage (Volts) OPTIONS, If your application of the Model 8712C/U/H includes the use of options such as multidrop communications, positive zero return (PZR), CONSIDERATIONS, AND auxiliary output control, or pulse output, certain requirements may PROCEDURES apply in addition to those previously listed.
Model 8712C/U/H Magnetic Flowmeter Transmitters Connect 4–20 mA Loop The 4–20 mA output loop provides the process variable output from the transmitter. Its signal may be powered internally or externally. The External Power Source default position of the internal/external analog power jumper is in the internal position.
Installation Connect Pulse Output The pulse output function provides an optically isolated switch-closure frequency output signal that is proportional to the flow through the Power Source flowtube. The signal is typically used in conjunction with an external totalizer or control system. The following requirements apply: Supply Voltage: 5 to 24 V dc Load Resistance: 1,000 to 100 k ohms (typical...
