Connecting Inlet Filter

The 5300 Series Gas Flow Multi-Meters have an exposed thermal flow sensor that is highly sensitive to foreign matter and particles within the gas flow. TSI® supplies inlet filters for both low pressure and high pressure applications and recommends that these filters be used at all times while testing with the instrument. After attaching the inlet filter, connect the flow tube to the inlet side of the filter.
If you are measuring a bidirectional gas flow and are concerned about foreign matter or particles entering the flow stream from either side of your test setup, TSI® recommends an inlet filter be placed on both sides of the meter.
CAUTION
Always use a filter on the inlet of the flow meter. Failure to filter the gas flow may change the calibration and/or permanently damage the sensor.
NOTE
Connecting a second inlet filter or tube to the outlet side of the 5300 Series Gas Flow Multi-Meter will create back pressure. In general, minimize back pressure on the meter to maintain the highest possible accuracy.
See Appendix A for the pressure drop created by connecting the supplied inlet filters to the 5300 Series Multi-Meter along with additional specifications.

Meter Operation
CAUTION
TSI® flow meters are not medical devices under FDA 510k and in no situation should they be utilized for human respiration measurements.

Getting Started

Power Button

The Multi-Meter may turn itself on once it is supplied with power. If the meter does not turn on automatically, press the Power button on top of the meter and the unit will power ON. To turn the instrument OFF, press and hold the Power button for 5 seconds.

Initialization and Warm-Up

It takes approximately 40 seconds for the 5300 Series Gas Flow Multi-Meter to initialize and warm-up. A TSI® splash screen will be displayed during this initialization period. Once this process has completed, the Flow Multi-Meter will begin displaying measurements and users will be able to fully operate meter. No additional meter warm-up time is needed.

Touchscreen Display

The 5300 Series meters utilize a 2.8-inch color LCD touchscreen display for easy viewing and operation. The touchscreen display is resistive and responds to pressure applied from a finger, stylus, or other instrument. The Flow Multi-Meter touchscreen can be operated while wearing gloves.

Measurement Parameters

The 5300 Series Gas Flow Multi-Meter measures flow rate, flow volume, temperature, absolute pressure, low differential pressure (Models 5310, 5320, 5330 only), and relative humidity (Models 5320 and 5330 only). All measurements made by the 5300 Series Multi-Meter are NIST traceable.

Flow Measurement

The 5300 Series Gas Flow Multi-Meters incorporate TSI® Incorporated’s proprietary platinum film sensor designed for measuring gas flows with high accuracy and fast response time while minimizing the pressure drop. Flow measurements are bi-directional and depending on the model can be selected to measure air, oxygen, air/oxygen mixtures, nitrogen, and carbon dioxide. Flow measurement data is available on the meter, through FLO-Sight™ PC Software, or via ASCII commands.
Meter Orientation
Although the 5300 Series can measure flow in both directions, TSI® recommends that flow be run through the meter from left to right as this is the orientation in which the meter was calibrated. There is an arrow printed on the bottom of the meter for reference.
Flow measured in this direction will be displayed as positive while flow measured in the reverse direction will be shown as negative.
For maximum flow accuracy at low flows, TSI® also recommends that the meter be run in a horizontal orientation.
18 Gas Flow Multi-Meter Models 5300/5310/5320/5330/5303

Temperature Measurement

The 5300 Series Multi-Meters have an independent temperature transducer in the flow tube to measure and display the gas temperature. The temperature sensor is also used for temperature compensation of flow rate and for converting flow from standard to volumetric units. Temperature measurement data is available on the meter, through FLO-Sight™ PC Software, or via ASCII commands.
NOTE
At low flow rates, the temperature inside of the flow tube will increase because of the heat generated by the thermal flow sensor. This effect is normal and the temperature of the incoming gas will be measured once flow resumes.

Absolute Pressure Measurement

The 5300 Series Multi-Meters measure absolute or barometric pressure near the outlet of the flow path. This pressure measurement is required for converting standard flow to volumetric flow. Absolute pressure measurement data is available on the meter, through FLO-Sight™ PC Software, or via ASCII commands.

Low Differential Pressure Measurement

Models 5310, 5320, and 5330 Gas Flow Multi-Meters have the ability to measure differential pressure, also known as breathing circuit pressure. The pressure differential of flows can be measured at the meter or at any point along the circuit. Low pressure measurement data is available on the meter, through FLO-Sight™ PC Software, or via ASCII commands. When combined with absolute pressure, low pressure readings can be used to calculate a volume flow rate at a remote point in the system. See Appendix D for more information on Remote Flow Measurements.

Relative Humidity Measurement

Models 5320 and 5330 Gas Flow Multi-Meter includes a relative humidity sensor near the inlet of the flow path. In addition to providing a humidity measurement, sensor readings are used to compensate the air flow for humidity effects to provide an equivalent dry-gas flow measurement. Relative humidity measurement data is available through the meter, FLO-Sight™ PC Software, or via ASCII commands.
NOTE
Humidity compensation does not apply to oxygen or carbon dioxide gas flows.

Volume Measurement

5300 Series Gas Flow Multi-Meters measure total volume by integrating flow over time. This is a calculated measurement performed by the Multi-Meter and is controlled through triggers. You can set begin and end triggers for volume measurements using flow rate, absolute pressure, or low differential pressure values.
See the topic “Volume and Triggers in Chapter 4 of this manual for more information on triggering and volume measurements. For models 5310, 5320, and 5330 you can set triggers and take volume measurements through the meter or with FLO-Sight™ PC Software. Volume measurements are available via ASCII commands for all 5300 Series models.

Totalizer Measurement

All 5300 Series Gas Flow Multi-Meters include a totalizer feature that measures total volume by integrating flow over time. This is a calculated measurement performed by the meter and operates as a running total. The totalizer count begins automatically when the meter is powered on regardless if the totalizer parameter is displayed or not. You can reset the totalizer count back to zero within the meter. Totalizer measurements can be viewed on the meter and in FLO-SightPC Software.
Operation and Service Manual 19

Units of Measurement

The 5300 Series Gas Flow Multi-Meter allows for user-selectable units of measurement options for all available measurement parameters. Units of measurement can be configured directly through the meter or with FLO-SightPC Software. Please see "Configuring the Meter" in Chapter 4 for instructions on changing units.

Standard Flow Rate vs. Volumetric Flow Rate
Since thermal flow sensors are sensitive to changes in air density and air velocity, all thermal flow meters indicate flow rates with reference to a set of standard conditions. For TSI® instruments, standard conditions are defined as 21.1°C (70°F) and 101.3 kPa (14.7 psia). Other manufacturers may use different values.
Standard flow rate is the equivalent flow rate the gas would be moving at if the temperature and pressure were at standard conditions. It is usually the most useful measure of gas flow because it defines the mass flow, number of molecules, and heat-carrying capacity of the gas.
Volumetric flow rate is the actual volume flow of the gas exiting the Flow Meter. In some instances, volumetric flow rate rather than standard flow rate may be of interest. To display
the volumetric flow rate, the 5000 Series Multi-Meter will multiply the standard flow measurement by the following density correction factor:
Volumetric Flow = Q  
T

std
 
P

Where:
Q = Standard flow rate Tm = Gas temperature measured in flow tube in units of degrees Celsius
Pm = Absolute pressure measured in flow tube in units of kPa
TSI® Flow Meters use T
std
= 21.11oC and P
std
= 101.3 kPa absolute
Example: The mass flow rate measured by the TSI® Multi-Meter is 100 Std. L/min at 15°C and 117 kPa. The Multi-Meter calculates and displays the volumetric flow as follows.
Volumetric Flow = (100 std L/min) 󰇧

Humidity Compensation
TSI® models 5320 and 5330 can correct their flow measurement in the presence of moist air. Previous models of TSI® flow meters read up to 5% higher in moist air than in dry air. The change in flow reading was due partly from the added mass of water vapor and partly from the change in thermophysical gas properties introduced by mixing water vapor in air.
The 5320 and 5330 model flow meters use a humidity sensor to remove the effect of humidity on the flow measurement. With humidity compensation turned on, the meter will indicate the flow in terms of dry air. In other words, the flow measurement will display the amount of air flow minus the water vapor present.
NOTE
Humidity compensation is only available when measuring the flow of air.

Disable / Enable Humidity Compensation

Users have the option to disable the humidity compensation feature on their Flow Multi-Meter. With humidity compensation disabled, the meter will deliver flow readings irrespective of the water vapor present in the gas flow. The humidity compensation feature is set to enabled as the default.
To disable humidity compensation, select the Gear icon from the Menu header bar. On the 4040 Mode tab, select EDIT, click the Humidity Compensation toggle switch, and SAVE. Select the toggle switch again to enable the feature.
Humidity compensation has also be disabled / enabled through FLO-SightPC Software.

Remote Flow

Theory of Operation

When combined with absolute pressure, low pressure readings can be used to calculate a volume flow rate at a remote point in the system. When set to remote flow measurement, the low pressure value is added to the absolute pressure measured in the channel of the instrument to convert the mass flow of gas at the instrument to volumetric flow at the remote location. The tubing should be connected from the positive (+) port on the instrument a tap at the remote location.
NOTE
The remote flow measurement assumes that the gas temperature is consistent between the two measurement locations. If the gas temperature between the measurement locations is significantly different, the remote flow measurement will no longer deliver a true reading.

Remote Flow Setup

The setup below shows air flowing through two 5000 Series meters in a line. Meter #1 is measuring upstream of the valve and meter #2 is measuring downstream of the valve. Both meters are measuring volumetric flow using the actual temperature and pressure of the air flow.
58 Gas Flow Multi-Meter Models 5300/5310/5320/5330/5303
With similar temperature and pressure conditions, the volumetric flow rate between the two measurement points is consistent.
Meter #1 Meter #2
Back pressure is introduced upstream of the valve. The increased pressure of air being measured by Meter #1 causes the volumetric flow reading to decrease. Meter #2 does not experience an increase in pressure and its flow reading remains steady. The remote flow measurement is taken upstream of the valve and is consistent with the volumetric flow reading from Meter #1 at the same location in the line.
