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

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.

Output

full Signal Appropriate

Actual gas = scale x (Vdc) x sensor conversion

flow rate N

factor of the new gas

Flow 5.000

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.
