2-5 Transit Precautions
To safeguard against damage during transit, transport the instrument to the
installation site in the same container used for transportation from the
factory if circumstances permit.
2-6 Removal from Storage
Upon removal from storage, a visual inspection should be conducted to
verify the condition of the equipment is “as received.” If the equipment has
been in storage in conditions in excess of those recommended (See
Section 2-3), the device should be subjected to a pneumatic pressure test
in accordance with applicable vessel codes.
2-7 Installation Tips (Refer to Figure 2-1)
a. The MassRate 5700 should be located in a clean dry atmosphere
relatively free from shock and vibration.
b. Leave sufficient room for access to the electrical components.
c. The MassRate 5700 Flowmeter can be installed in any position.
However, mounting orientations other than the original horizontal factory
calibration couldresult in a ±0.5% maximum full scale shift after
re-zeroing.
d.When installing flowmeters, be aware that sharp abrupt angles in the
system piping directly upstream of the meter may cause a small shift in
accuracy. If possible, have 10 pipe diameters of straight tubing upstream of
the MassRate
5700 Flowmeter.

2-8 In-Line Filter
It is recommended that an in-line filter be installed upstream from the
flowmeter to prevent the possibility of any foreign material entering the flow
sensor. Refer to Table 2-1 for recommended filter size. The filter should be
periodically replaced or ultrasonically cleaned.
Flow Rate Filter Size

Table 2-1 Recommended Filter Size
2-9 Positive Shut-Off Valve
It is recommended that a positive shut-off valve be installed in-line with the
MassRate 5700. The position of this valve, upstream or downstream of the
meter will depend upon the specific application.
2-10 Gas Connections
The MassRate 5700 comes with integrally machined 1/4" female NPT
mechanical connections. Optional 1/8", 1/4", or 3/8" compression fittings
may be supplied with the meter. For flow rates above 10 slpm, 3/8"
compression fittings are recommended. It is recommended that 1/4" wide
pipe tape, not pipe dope, be used to install fittings or adapters into this
meter. The following steps should be followed during mechanical
installation:
a.Clean both male and female tapered thread ends to ensure removal of
dirt or previously applied antiseize compound or tape.
b.Beginning at the first thread, wrap tape in the direction of the male
tapered thread spiral, and join with a slight overlap. (Two wraps are
suggested for stainless steel tapered pipe threads.)
c.Make sure tape does not overhang the first thread, as the tape could
shred and get into the fluid system.
d.Cut off excess tape. Draw the free end of the tapearound the threads
tautly so that it conforms to the threads. Press firmly at the overlay point.
The connection is now ready for proper make-up.
The entire system should be pressurized and leak tested with a dry inert
gas prior to operation.

Section 2 Installation
2-11 Electrical Interfacing
To insure proper operation, the MassRate 5700 must be connected per
Figure 2-1. A positive 12 to 15 Vdc power source must be connected to pin
1 and common to pin 5. Under normal operating conditions this meter will
draw less than 50 mA. The flow output is a linear 0-5 Vdc signal on pins 2
and 4.
The electrical connector is a 5 pin post header horizontal mount AMP
171826-5. The recommended mating connector is AMP 172053-5.
NOTE: IF MassRate 5700 is going to be located in a noisy
environment (motors, pumps, etc.), it is recommended that the body
is connected to earth ground. This can be done by attaching a
ground wire to either mounting screw.
2-12 Zero Adjustment
Each MassRate 5700 is factory adjusted to provide a 0 ±10mVdc signal at
zero flow. If readjustment is necessary refer to Figure 2-1 for zero
potentiometer location and follow instructions a through f listed below.
a.Mount the flowmeter in its final configuration.
b.Close the in-line positive shutoff valve. Turn on the gas supply and/or
vacuum system.
c.Apply 12 to 15 Vdc and allow 20 minutes for the instrument to warmup
and stabilize.
d.Using a suitable voltmeter check the flowmeter output signal on pins 2
and 4.
e.If the output is not 0 ±10 mVdc check the system for leaks.
f. If no leaks are found adjust the zero potentiometer until the desired
output is obtained.

a. Close the in-line positive shutoff valve.
b. Turn on the gas supply and/or vacuum system.
c. Apply 12 to 15 Vdc and allow 20 minutes for the instrument to
warmup and stabilize.
d. Adjust zero potentiometer if necessary. Refer to Zero Adjustment
Section 2-8.
e. Open the valve to allow flow to pass through the meter. Monitor the
flow output signal.
3-2 Output Signal
The flow output from the MassRate 5700 is a 0-5 Vdc signal linear with
flow rate. Some output versus flow points are shown in Table 3-1 for
reference.
3-3 Process Flow Rate
Each MassRate 5700 is calibrated on Nitrogen for a specific full scale flow
rate. That flow rate is indicated on the label of the instrument. If a process
gas other than Nitrogen is specified when the instrument is ordered, a
conversion factor based on the specific heat of the process gas is used to
determine a new full scale flow. This process gas and new full scale flow
will also be indicated on the label. If using a process gas other than that
specified at the time of order placement, a new full scale flow can be
determined as detailed in Section 3-4.

3-4 Use of Conversion Factors
A list of sensor conversion factors is given in Table 3-2. To change to a new
gas, multiply the meter output by the sensor factor for the new gas.

Example:
The flowmeter is calibrated for 10 slpm Nitrogen.
The process gas is carbon dioxide.
The flowmeter output is 3.750 volts (75%).
What is the actual carbon dioxide flow?
Actual CO

= 10 x 3.75 Vdc x .773
flow rate slpm 5.0 Vdc
= 7.5 slpm x .773 = 5.798 slpm
In order to calculate the conversion factor for a gas mixture the following
formula should be used:
Sensor 100
Conversion = P1 P2 Pn
sensor + sensor + sensor
conversion conversion conversion
factor 1 factor 2 factor n
Where, P1 = percentage (%) of gas 1 (by volume)
P2 = percentage (%) of gas 2 (by volume)
Pn = percentage (%) of gas n (by volume)
Example:
The gas is 20% Helium (He) and 80% Chlorine (CI) by volume.
Sensor conversion factor for the mixture is:
100
Mixture = = .946
Factor 20 + 80
1.386 .876
It is generally accepted that the flow rate derived from this equation is only
accurate to ±5%. The sensor conversion factors given in Table 3-2 are
calculated based on a gas temperature of 21°C and a pressure of one
atmosphere. Gas conditions that vary widely from these reference
conditions may cause an additional error due to the change in specific
heat.

Section 4 Maintenance &
Troubleshooting
4-1 General
No routine maintenance is required on the MassRate 5700. If an in-line
filter is used, it should be periodically replaced or ultrasonically cleaned.
4-2 Troubleshooting
A. System Checks
The MassRate 5700 is generally used as a component in gas handling
systems which can be quite complex. This can make the task of isolating a
malfunction in the system a difficult one. An incorrectly diagnosed
malfunction can cause many hours of unnecessary downtime. If possible,
make the following system checks before removing a suspected defective
flowmeter for bench troubleshooting or return, especially if the system is
new.

Section 4 Maintenance &
Troubleshooting
B. Bench Troubleshooting
1. Properly connect the mass flowmeter to a 12 to 15 Vdc power supply.
Connect an output signal readout device, 4-1/2 digit voltmeter is
recommended to pins 2 and 4 of connector (refer to Figure 2-1). Apply
power, and allow the flowmeter to warm up for 20 minutes. Do not
connect to a gas source at this time. Observe the output signal and, if
necessary perform the zero adjustment procedure (Section 2-8). If the
output signal will not zero properly, refer to the Sensor
Troubleshooting, Section 4-2c. If the sensor is electrically functional,
the printed circuit board may be defective and will require
replacement. If the instrument requires service, contact the Brooks
Product Service Group for a R.M.A. number.
2. Connect the flowmeter to a gas source. Nitrogen or air should be used
for this bench test. Increase the flow until 100% indication (5.00 Vdc)
is achieved. Vary the flow rate over the 5 to 100% range and verify that
the output signal follows the flow rate. If possible, connect a flow
measurement device in series with the flowmeter to observe the actual
flow behavior and verify the accuracy of the flowmeter. If the flowmeter
functions as described above, it is functioning properly, and the
problem may lie elsewhere. Refer to Table 4-1 for additional troubleshooting.
C. Sensor Troubleshooting
If it is believed the sensor coils are either open or shorted. Remove the
cover can. Remove the PCB.
Unplug sensor flex cable from the PCB. Troubleshoot using Table 4-2. If
any of the steps do not produce the expected results the sensor assembly
is defective and the flowmeter should be returned to the factory.
1. Verify a low resistance common connection and that the correct
power supply voltage and signals are reaching and leaving the meter.
Refer to Section 2-7.
2. Verify that the process gas connections have been correctly
terminated and leak checked, and gas supply is on. Refer to Section 2-6.
