Pulse output
The Rosemount 8600D comes with an optional pulse output option (P). This enables the
flowmeter to output the pulse rate to an external control system, totalizer, or other device.
If the flowmeter was ordered with the pulse mode option, it may be configured for either
pulse scaling (based on rate or unit) or shedding frequency output. There are four methods
for configuring the pulse output:
 Off
 Direct (Shedding Frequency)
 Scaled Volume
 Scaled Velocity
 Scaled Mass
Direct (shedding frequency )
This mode provides the vortex shedding frequency as output. In this mode, the software
does not compensate the K-factor for effects such as thermal expansion or differing mating
pipe inside diameters. Scaled pulse mode must be used to compensate the K-factor for
thermal expansion and mating pipe effects.
Scaled volume
Allows you to configure the pulse output based on a volumetric flow rate. For example, set
100 gallons per minute = 10,000 Hz. (The user enterable parameters are flow rate and
frequency.)
Pulse scaling rate
Allows the user to set a certain volume flow rate to a desired Frequency.
For example:
1. Enter a flow rate of 100 gallons per minute.
2. Enter a frequency of 10,000 Hz.
Pulse scaling unit
Allows the user to set one pulse equal to a desired volume.
For example:
1 pulse = 100 gal. Enter 100 for the Flow Rate.
