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
This mode 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
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
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.
Scaled Velocity
This mode allows you to configure the pulse output based on a velocity Flow
Rate.
Pulse Scaling Rate
Allows the user to set a certain velocity flow rate to a desired frequency.
For example:
10 ft/sec = 10,000HZ
1. Enter a Flow rate of 10 ft/sec.
2. Enter a Frequency of 10,000HZ.
Pulse Scaling Unit
Allows the user to set one pulse equal to a desired distance.
