SUPERtrol II
Description:
The SUPERtrol II Flow Computer satises the instrument
requirements for a variety of owmeter types in liquid, gas, steam
and heat applications. Multiple ow equations are available in a
single instrument with many advanced features.
The alphanumeric display offers measured parameters in easy to
understand format. Manual access to measurements and display
scrolling is supported
The versatility of the Flow Computer permits a wide measure of
versatility within the instrument package. The various hardware
inputs and outputs can be soft assigned to meet a variety of
common application needs. The user soft selects the usage of
each input/output while conguring the instrument. Consider the
following illustrative examples.
The isolated analog output can be chosen to follow the volume
ow, corrected volume ow, mass ow, temperature, pressure,
or density by means of a menu selection. Most hardware features
are assignable by this method.
The user can assign the standard RS-232 Serial Port for external
data logging, transaction printing, or for connection to a modem
for remote meter reading.
A Service or Test mode is provided to assist the user during start-
up system check out by monitoring inputs and exercising outputs.
The system setup can also be printed.
