2.3 Precautions for Measurements

Direction Mark

2.3.1 Air Velocity Measurement Precautions

 Probe has its own directivity characteristics. Make sure that the direction mark is

facing against the airflow (for details of the directivity characteristics, refer to Section

12 “Probe Directivity”). If you are not sure of the airflow direction, slowly rotate the

probe and select the point where you get the maximum velocity reading,

 The probe compensates air velocity change due to temperature change by using the air velocity

sensor with the temperature compensation sensor. In order to obtain this compensation effect, it

is required that both sensors are evenly exposed to the airflow under the same temperature

condition.

 For measurements in an environment with rapid temperature change, you must wait for the

reading to become stable after measuring for more than 20 seconds before taking the data.

Airflow

2.3.2 Air Temperature Measurement Precautions

 The response time for temperature measurement improves as the air velocity increases. The normal response

time is approximately 5 seconds when the air velocity is 1m/s. You must wait for the reading to become stable

before taking the data.



When a measurement is performed in a no-airflow condition, the air temperature reading may become higher

than actual due to the heat generated by the air velocity sensor. It is recommended that the measurement is

performed in an environment with at least 0.1m/s airflow to obtain accurate readings.

2.3.3 Differential Pressure Measurement Precautions (A041, A044)

 Do not apply pressure more than 75kPa to the pressure sensor. Excess pressure may cause permanent damage to

the sensor.

 The operating temperature is 5 - 40

There are two duct shapes - Rectangular and Circular, which are indicated as and at the lower

right corner of the LCD screen.

For a circular duct, set the diameter (D).

Maximum dimension of a side: 2550mm

Input Increment: Range of 0 to 1000mm: 1mm

Range of 1000 to 2550: 10mm

To recover from the hold mode, press the key again.

By pressing the key while the reading is held, the displayed

reading will be saved temporarily in the memory, and hold mode will be

released to resume measurement.

For how to store the data, refer to Section5.2 “Data Storage and

Statistical Calculation Procedure” (P.15).

12

4.3 Setting the Time Constant

When there is rapid change in the measurement data, the readings may become difficult to read. In such case, the speed

of updating the readings can be reduced by changing the time constant setting.

Time constant determines the time span of the moving average. When a larger (longer) time constant is selected, the

readings will be rather stable, and when a smaller (shorter) time constant is selected, the readings will be more

responsive and sensitive to the change.

The time constant can be selected from 1, 5, 10 or 20 seconds by pressing the key.

8. Cleaning the Probe

When the sensor is contaminated with impurities such as dust, particles, soot or machine oil, the heat dissipation rate

will change. In most cases, heat dissipation will decrease, resulting in lower air velocity readings.

This is same for the probes which are equipped with a mesh cover. The same problem will occur if the mesh is deformed,

or clogged with impurities.

If impurities are attached to the sensor or mesh from using the instrument in an unclean environment, it is recommended

that the sensor is cleaned right after use.

Clean the sensor of the probe in an ultrasonic cleaner for approx. 10-20 sec.

Do not clean the sensor longer than required as excess cleaning will lead to sensor coating damage.

Use water for cleaning.

The sensor can also be cleaned in a vessel filled with neutral detergent diluted with water, and by gentl

stirring it in the vessel.

! Caution !

!) Make sure to TURN OFF the power before cleaning.

Dry the probe completely after cleaning. Do not turn on the power before completely dried.

10. Measurement Principles

Hot-wire Anemometer Principle

When the heated air velocity sensor is exposed to airflow, the sensor

temperature will change by the heat drawn by the airflow. Accordingly, the

sensor resistance value will change. This change in the resistance value will

vary largely as the air velocity increases. Therefore, if the relationship

between the air velocity and the resistance value is known, the air velocity can

Airflow

be obtained by measuring the resistance value (or current).

Air velocity sensor (platinum coil)

The Anemomaster anemometer is based on the above principle.

Generally, a hot-wire anemometer employs a feedback circuit to control the sensor to

maintain constant temperature. (Constant Temperature Type)

When there is a change in the air velocity, the heat drawn from the sensor (heat dissipation)

will change accordingly. In order to maintain constant temperature, current is applied to the

Current i

Ve lo c i ty Sensor

sensor to compensate this change. Thus, the air velocity value can be obtained from the

amount of the applied current (i).

The amount of heat [H] drawn from the air velocity sensor can be expressed by the following

formula.

Where;

H: Heat Dissipation T: Sensor Temperature Ta: Air Temperature

U: Air Velocity a,b: Constant

The Heat Dissipation [H] can also be expressed by the following formula from the sensor
resistance (R) and current (i).

in the current “i”.

 Temperature Compensation

When the air temperature changes, the amount of heat dissipation will change accordingly even when the air velocity is

constant. Thus, Anemomaster employs a temperature compensation circuit to enable accurate air velocity measurement

by eliminating the influence of the temperature change. For this purpose, a temperature measurement sensor Rc having

the same temperature coefficient as the air velocity is provided at the opposite side of the bridge, and the bridge is

adjusted so that the difference with the air temperature (T-Ta) is kept constant.

Air Temperature Measurement

An air temperature element (platinum thin film element) which its resistance value changes by the air temperature is

incorporated in one side of the bridge. The air temperature can be obtained by measuring the variance in the resistance

value.

Pressure Measurement (A041, A044)

A diffusion-type semiconductor pressure sensor is employed to measure the pressure. This diffusion-type

semiconductor pressure sensor is based on the Piezoreistance Effect, in which the resistance value changes when the

pressure is applied. It is configured with four (4) diffusion resistances (sensor chips) located on the thin silicon

diaphragm (Fig. 1).

The pressure is applied from above the pressure sensors, and when the diaphragm is deflected as shown in Fig. 2,

compressive stress is applied to R3 and R4 which are located at the center of the diaphragm, and tensile stress is applied

to R1 and R2. The resistance value of the diffusion resistance changes in accordance with the strength of the stress

applied.

By configuring the bridge of the detection circuit with these diffusion resistances, voltage that is proportional to the

pressure can be obtained. In addition, since the diffusion resistance is dependent on temperature, temperature

compensation resistance is employed for the resistance.

11. Air Velocity Compensation

When the heated air velocity sensor of the instrument is exposed to airflow, the heat is drawn from the sensor. The

instrument obtains air velocity readings by using this relationship between the amount of heat removed (heat

dissipation) and air velocity.

Since the instrument is calibrated with clean airflow with normal temperature and pressure, when the condition of air to

be measured is different from that of the air used for calibration, the heat dissipation amount will differ even when the

velocity is consistent (i.e. velocity reading is influenced by the condition of air).

11.1 Influence of Air Temperature

The instrument is a hot-wire anemometer, which measures the air velocity by using the heat dissipation amount. Thus,

if temperature compensation is not provided, air velocity readings will by affected by the ambient air temperature

change even when the air velocity is consistent. In order to prevent such influence, the instrument is equipped with a

temperature compensation circuit for measuring and compensating the air temperature in the range of 5°C to 60°C.

11.2 Influence of Atmospheric Pressure

The instrument is calibrated under atmospheric pressure of 1013hPa. Since change in the atmospheric pressure will

influence the heat dissipation amount, compensation of the atmospheric pressure is required. Compensation can be

provided by using the following formula.

Where, Um: Actual Air Velocity [m/s]

Um ×=

Uc

Pm

Uc: Air Velocity Reading

Pm: Atmospheric Pressure at the Time of Sampling [hPa]

11.3 Influence of Air Composition

Compensation is required if the measurement is to be performed in an environment including any gas other than air.

Compensation shall be performed by calculating the heat dissipation amount from the physical properties of the gas,

and comparing it with the heat dissipation amount of the air.
