Quick Start Guide
Setup
• Connect your flow controller. Ensure that flow through your device will be
in the same direction as the arrow on the flow body (usually left to right).
• Tare your flow controller. Before you connect the flow meter, ensure
that no air is flowing through the device and give it a zero setpoint for
at least 2 seconds. Note: Whisper flow controllers are sensitive enough
to measure the lightest of breezes, so ensure that one end is plugged
before selecting tare.
• Choose your engineering units. Press the button above or below any
parameter to enlarge it in the middle of the display. If you select that
same item a second time, you can change the engineering unit for that
parameter. You can choose units for all of the parameters at once by
selecting MENU →BASIC CONFIG →DEVICE UNITS (see page 18).
Operation: Flow Verification
• Monitor live flow readings. You can monitor live readings of flow,
pressure, and temperature by viewing the screen. Readings are updated
in real time. See page 17.
• Tare your flow controller before you begin another round of
measurements. Ensure that no flow is passing through your controller
and wait for it to auto-tare. See page 22.
• (Optional) Capture a totalized reading. The totalizer option displays
the total flow that has passed through the device since the last time
the totalizer was reset. Press TOTAL/MENU to access the totalizer. See
page 19.
Backlight
Your Alicat monochrome display comes equipped with a backlight. To
activate the backlight, press the center of the Alicat logo on the front
of your device. To turn the backlight o press the button again. For color
displays, pressing this button will turn o the display to conserve power.
Maintenance and Care
• If your gas is clean, your flow meter will require no periodic cleaning.
Read more about maintenance on page 51.
• Calibrate your flow meter annually. Request an Alicat factory calibration
at alicat.com/service or by calling 1-888-290-6060.

Mounting
No straight runs of pipe are required upstream or downstream of the flow
controller. Most Alicat flow controllers can be mounted in any position,
including upside-down. MCS and MCRS series flow controllers use
media-isolated sensors that must be tared after changing orientation.
Caution: Flow controllers that use large Rolamite valves
(MCR, MCRW, MCRQ, MCRS) should be mounted with
their valve oriented vertically (right-side up). If another
orientation is desired, please contact Alicat.
Filters
When pressure drop is not an issue, use in-line sintered filters to prevent
large particulates from entering the flow controller. Suggested maximum
particulate sizes are as follows:
• 5 microns for units with flow ranges of 1  or less.
• 20 microns for units with flow ranges between 2  and 1 .
• 50 microns for units with flow ranges of 1  or more.
Device Ports
Your controller has been shipped with plastic plugs fitted into its ports.
To lessen the chance of contaminating the flow stream, do not remove
these plugs until you are ready to install the device.
Standard Alicat Gas Flow controllers have female inlet and outlet ports.
Welded VCR and other specialty fittings may have male connections.
• If you are using a fitting that does not have a face seal, use
thread-sealing Teflon tape to prevent leakage around the
port threads, but do not wrap the first two threads. This
will minimize the possibility of getting tape into the flow
stream and clogging the laminar flow elements (LFEs).
• If you are using a fitting that has a face seal, there is
no need to apply Teflon tape to the threads.
! Warning: It is not recommended to use pipe dopes
or sealants on the process connections as these
compounds can cause permanent damage to the
controller should they get into the flow stream.

10 Getting Started
Connecting Plumbing to
Your Gas Flow Controller
Your Alicat flow controller can measure and control flow generated by
positive pressure and/or suction. Connect the controller so that the flow
travels in the same direction as the flow arrow, usually from left to right
as you look at the front of the device.
Note: On instruments set up for vacuum or gas mixing, the control valve
will be situated in the down-stream position.

Connection Outlet
Connection
Flow Direction Indicator
! Warning: Using the flow controller above the maximum specified
internal line pressure, or above the maximum recommended
dierential pressure between the inlet and outlet, will result
in permanent damage to the internal pressure sensors.
A common cause of this problem is the instantaneous
application of high-pressure gas, as from a snap-acting
solenoid valve either upstream or downstream of the flow
controller. If you suspect that your pressure sensor is damaged,
please discontinue use of the device and contact Alicat.

MCV Controller Operating Notes
Alicat’s MCV mass flow controller is equipped with an integrated Swagelok®
positive shuto valve. The normally closed valve is opened by supplying
with 60120  of air pressure. The shut-o valve closes again when
this pressure is removed.
A common method for actuating the shuto valve incorporates a three-way
solenoid valve (below). Pressure is applied to one side of the solenoid valve
while the other side of the solenoid is left open to atmosphere. When the
solenoid is energized, pressure is delivered to the shuto valve, causing
it to open. When the solenoid is returned to a relaxed state, the gas vents
to atmosphere, allowing the shut-o valve to close.
✓ All standard MC-Series device features and functions are
available on the MCV Series and operate in accordance
with the standard MC Series operating instructions.

Power and Signal Connections
Power can be supplied to your controller through either the power jack
or the multi-pin connector on top of your device.
✓ Small valve controller power jacks require a 1224 Vdc power
supply with a 2.1 mm female positive center plug capable of
supplying at least 250 mA. 420 mA analog signal outputs require
at least 15 Vdc, and 010 Vdc outputs require at least 10 Vdc.
Large valve controllers (MCR models) require a 24 Vdc power supply with a
2.1 mm female positive center plug capable of supplying at least 1 A.

options ordered. Optional configurations are noted on the unit’s calibration sheet.
Caution: Do not connect power to pins 1 through 6, as permanent
damage can occur. It is common to mistake Pin 2 (labeled 5.12 Vdc
Output) as the standard 0–5 Vdc analog output signal. Pin 2 is
normally a constant 5.12 Vdc that reflects the system bus voltage.
For 6-pin locking industrial connector, M12, DB9, and DB15 pinouts,

Analog Signals
Primary Analog Output Signal
Most Alicat instruments include a primary analog output signal, which is
linear over its entire range. For both standard 0–5 Vdc and optional 0–10
Vdc output signals, a zero flow condition is usually in the range of 0.010 Vdc.
Zero flow for the optional 1–5 Vdc and 4–20 mA output signals is 1 Vdc and
4 mA, respectively. Full scale flow is 5 Vdc for 0–5 Vdc and 1–5 Vdc signals,
10 Vdc for 0–10 Vdc signals and 20 mA for 4–20 mA signals.
Alicat’s default 8-pin mini-DIN connector places the primary analog output
on Pin 6 for voltage signals and Pin 1 for 4–20 mA current signals. Ground
for these signals is common on Pin 8.
Option: Second Analog Output Signal
Alicat’s default 8-pin mini-DIN connector places the secondary analog
output on Pin 2 for both voltage and current signals. Your device’s
secondary analog signal may dier from its primary output signal.
✓ See the calibration sheet that shipped with your controller
to determine which output signals were ordered.
Option: 4–20 mA Current Output Signal
If your controller has a 4–20 mA current primary or secondary output
signal, your flow controller will require 15–30 Vdc power.
Caution: Do not connect 4–20 mA devices to “loop powered”
systems, as this will destroy portions of the circuitry and void the
warranty. If you must interface with existing loop powered systems,
always use a signal isolator and a separate power supply.

2020.02.05  REV. 0 15
Option: Color TFT Display
Instruments ordered with a color display function the same as standard
backlit monochrome instruments, but color is used to provide additional
on-screen information.
Multi-Color Display Indicators
• GREEN: Parameter labels and adjustments associated with the
button directly above or below the label are presented in green.
• WHITE: A parameter is displayed in white while
operating under normal conditions.
• RED: A parameter is displayed in red when its value
exceeds 128% of the device’s specifications.
• YELLOW: Menu items that are ready to be selected
appear in yellow. This color replaces the symbol
(>) in selections on monochrome display.
✓ Press the Alicat logo button to turn o the color
display backlight. The flow controller remains
in operation while the backlight is o.
LCD Contrast
LCD contrast is ranged from  to 11 on color displays, with 11 indicating
the greatest contrast. See “Display Setup” on page 39.
Specifications for Instruments with Color Displays
Color displays will require an additional 40 mA when using a 24 Vdc
power supply. All other specifications from your device’s specification
sheet remain in eect.

Option: Totalized Flow Data
and BatchDispensing
Your ow controller may have an optional ow totalizer, which enablesbatch
dispensing. The totalizer displays the total amount of mass or volume that has
owed through the instrument since its last reset, like a gasoline pump. Access
the totalizer screen by pressing TOTAL/MENU on the Main Display.
Totalizer – Main Screen Totalizer Rollover Functions
Your flow totalizer has been configured to report a maximum of 7 digits. By
default, the placement of the decimal is the same as the live flow rate. The
totalizer can be configured at the time of order for the following behaviors.
(By default, the totalizer rolls over and displays OVR.)
• Rollover: Totalizer resumes counting from  as soon
as the maximum count has been reached.
• Freeze: Totalizer stops counting at max
count, until it is reset manually.
• Error: Displays OVR status message when maximum count
has been reached; compatible with Rollover and Freeze.
The elapsed time counter has a maximum value of 9999:59:59 (h:m:s) (416
days, 16 hours). If flow is still being totalized at that point, the timer freezes,
regardless of the behavior chosen above for the totalized flow readings.

How to start batch dispensing
1. From the totalizer screen, press BATCH. Choose the total quantity to
be dispensed in each batch. Press SET to accept the new batch size.
2. From the totalizer screen, press SETPT to choose a non-zero
setpoint. Flow begins as soon as you press SET.
✓ Note: Batch dispensing requires an active batch size and a non-zero
setpoint. If your controller already has a non-zero setpoint, flow
begins as soon as you press SET from the batch size screen.
3. While a new batch is being dispensed, the BATCH button
changes to show the quantity that remains to be dispensed.
When the batch size has been achieved, the BATCH
button displays -DONE- and flow stops automatically.
The batch size can be changed while a batch is in progress. If the new
batch size is larger than the current totalized flow, then flow continues
until the new value is reached. If the new batch size is smaller than the
current totalized flow, then the flow stops immediately. Press RESET to
start the new batch.
