Setup

375 Transducer Block, Detailed Setup, Additional Params

The PV minimum span is the minimum flow range that must separate the minimum and maximum configured PV Range values.

Reverse Flow

375 Transducer Block, Detailed Setup, Additional Params

Enable or disable the transmitter’s ability to read reverse flow.

Reverse Flow allows the transmitter to read negative flow. This may occur when flow in the pipe is going the negative direction, or when either electrode wires or coil wires are reversed. This also enables the totalizer to count in the reverse direction.

This allows you to configure the language shown on the display. There are five options available:

•English

•Spanish

•Portuguese

•German

•French

Signal Processing

375Transducer Block, Detailed

Setup

The 8732E contains several advanced functions that can be used to stabilize erratic outputs caused by process noise. The signal processing menu contains this functionality.

Operating Mode

375 Transducer Block, Detailed Setup, Signal Processing

The Operating Mode should be used only when the signal is noisy and gives an unstable output. Filter mode automatically uses 37 Hz coil drive mode and activates signal processing at the factory set default values. When using filter mode, perform an auto zero with no flow and a full sensor. Either of the parameters, coil drive mode or signal processing, may still be changed individually. Turning Signal Processing off or changing the coil drive frequency to 5 Hz will automatically change the Operating Mode from filter mode to normal mode.

Man Config DSP

375 Transducer Block, Detailed Setup, Signal Processing

Manually configure the digital signal processing parameters.

The 8732E transmitter includes digital signal processing capabilities that can be used to condition the output from the transmitter by enabling noise rejection. See Appendix D: Digital Signal Processing for more information on the DSP functionality.
