FlowScale
System
1.1
General
The Micro Motione FlowScale system measures and displays mass flow-rate and
mass flow-total information for fluids The FlowScale system uses a non-intrusive, ob-
struction-free sensor unit in a stainless steel housing. The sensor unit installs directly
into the process. The transmitter is enclosed in a NEMA
IV housing and can
be
in-
stalled up to
1000 feet (300 meters) from the sensor unit The microprocessor-based
FlowScale electronics system is ideal for custody transfer and other similar applica-
tions. A method for sealing
(i.e. tampe~proof) the FlowScale housing is provided for
approval agencies.
Note: Throughout this manual, the term "sensor refers to a sensing element only.
The term "flowmeter" refers to a combined sensor and
transmitter package.

Operational Features
Display: The Flowscale electronics' displav is a two line. sixteen character. fivebv-
seven dot matrix, liquid crystal display (i~d). Normally, the display is used for mass
flow-rate and mass
fiow-total information. The display is also used for programming
parameters and to indicate error codes.
Dlsplay Modes: There are three display modes: the Owrating Disdav Mode. the
Pa-
ramelei Select~on Disp!ay Mode, and the Error Recovery
is play
ode.
In tqe Oper-
ating Display Mode, the display indicates mass flow rate and mass
flow total .n user-
selected units. In the Parameter Selection Disoiav Mode. the dis~lav indicates the oa-
rameter (variable) to be programmed. The inventory total is alsodisplayed in the
Pi-
rameter Selection Display Mode. When in the Error Recovery Display Mode, the dis-
play indicates error codes and the time and date of their occurrence.
Front Panel Push-Button Kevs: The Mode. Increase. Decrease. and Clear
kevs are
on the front panel. In the openling D splay Mode, the Clear key is
sea
to clear (re
set) the totalizer. In the Parameter
Selectton Display Mode, all lour swltches on tte
front panel are used to change parameters. In the Error Recovery Display Mode, all
four switches are used to evaluate an error and to reset an
error (see Section
3.2.
Op-
erating Functions).
Zero Adjustment:
A
single switch within the FlowScale electronics sets the system
zero. The FlowScale unit contains a circuit which
corrects for the zero shift of the el-
ectronics.
Q
Secum Switch: The SECURE switch is located within the RowScale electronics (see
figure
15a). Wnen this sw:tch is in the on or ~nsecured position, the FlowScale elec-
tronics will allow any parameter to be changed. When the $witch is in the on or se-
cure position, the FlowScale electronics will not allow changes to critical parameters.
Inventory Total: An inventory total is maintained within the FlowScale electronics
and is displayed when in the Parameter Selection Display Mode.
Dlagnostlc
Functions:
The FlowScale electronics incorporates error chec~ing tunc-
tions which routinely monitor the operation o' both the sensor and transmitter. Errors
detected are coded-and stored in a non-volatile memory. A fault alarm output pro-
vides notification of a fault condition.
Flow conditions are also monitored to ensure that thev are within the installation's in-
tended parameters. Should
the
flow rate fall outside oi a preset flow range, an alarm is
energized. When flow direction is reversed, an alarm is activated.
1.3
Rogrammable Features
The FlowScaie transmitters' oroorammable functions are partitioned into
two
areas:
1)
those that are programmable;ia the front panel push-button key switches, and
'
2)
those that are programmable via internal switches.
1.3.1
Front
Panel
The following areas are programmable from the front panel:
RWrammable
Features
Mass and Time Units: Mass and time units for the flow rate and flow total are pro-
grammable. Available mass units are ounces, pounds, tons, kilograms and metric tons.
Available time units are seconds, minutes and hours.
Scaled Pulse: The
scaled-pllse output feature generates a pulse per unit of mass
measurement at a maximum rate of
10
pulses-per-second. The unit of mass measure-
ment is selected
by the user.
High and Low Alarms: The high and low alarm levels are programmable for mass
flow rale only.
Low flow Cutoff: The amount of "cutoff' applied to the flow rate signal can
be
se-
lected by the user. The use of a low flow cutoff eliminates unwanted low-level system
noise from the rate and total at zero flow.
Fllter Constant: The amount of filtenna amlied to the mass flow-rate signal is pro-
grammable through selection of the filler constant The ab'l'ty to select the filter
constant is part'cularly helplul in noisy or pulsat~ng flow systems.
Frequency Output Parameters (optional): The frequency output generates a fre-
auency Droportional to the mass flow rate. Scaling and sDan parameters are also Pro-
grammable:
Current Output Parameters (optional): The current output is factory programmed
as current and is typically configured as a
4
to
20
mA output The scaling and span
parameters of the current output are programmable from the front panel
Communications
Parameters (optional): All communications parameters are pro-
grammable from the front panel. These include
port
selection, unit identification num-
ber
(ID#), controller ID#, mode selection, baud, and parity.
1.3.2
Internally Programmable Internally programmable functions require that the upper front cover of the FlowScale
Features
unit be removed before these functions can be programmed or changed. This pre-
vents accidental altering and provides security for the internally programmed parame
ters.
The following are internally programmable:
Meter Type and Meter Factor: The METER TYPE switches allow the FlowScale el-
ectronics to be attached to any sensor unit. The METER FACTOR switch is used to
establish the scaling of the system. The METER
TYPE
and METER FACTOR switches
are set at the factory
to
appropriate positions. These switches may be changed
if
nec-
essary for recalibration or use with a different sensor.
Securitv: The SECURE switch selects the securitv mode. When in the securitv mode.
the ~low~cale electronics will not allow changes to key parameters. The key parame
ters are mass units, time units, scale0 pulse selection, high alarm level. low a<arm ev-
el, low flow cutoff, filler constant, all communication parameters, time and date.
Declmal PolntIComma: When the COMMA switch is in the up or decimal position,
all breaks between whole numbers and fractions will be displayed with decimal points.
When the switch is in the down or comma position, all breaks between whole num-
bers and fractions will be displayed with commas.
1.3.3
Error
Recovery Modes
The FlowScale electronics contains extensive diagnostic and self-testing capabilities in
order to ensure
accJrate flow measurement and diagnostics operation. Errors are
stored in a nonvolatile memorv and the
25
most-recent errors are saved together with
the time and date of error oc&rrence. Two modes of recovery from errors ire availa-
ble and can be selected via an internal switch. The manual mode requires manual or
communications port intervention to clear an error. In the auto recovery mode, the
FlowScale
electronics
w~ll attempt to recover on its own
