TAIO ... ZG2b (Meas. A Page 2)

nnnn

Measurable variable

nnnn

standard velocity Nv, standard

nnnn

volume flow NV/t,

nnnn

mass flow proportional

nnnn

norm:

nnnn

temperature tn = +21 °C,

nnnn

pressure pn = 1014 hPa

nnnn

Functional principle

nnnn

measurement of flow according

nnnn

to heat transfer method

nnnn

temperature dependence of

nnnn

measurement compensated by

nnnn

complete temperature operating

nnnn

range

nnnn

Design

nnnn

Probe with integrated transducer

nnnn

Gases

nnnn

pure gases, gas mixtures:

nnnn

air, nitrogen, methane, natural

nnnn

gas, argon, carbon dioxide,

nnnn

helium, sulphur hexafluoride,

nnnn

landfill gas ...

nnnn

a calibration with a multitude of

nnnn

gases or gas mixtures can be

nnnn

carried out to achieve the

nnnn

slightest measuring uncertainty

nnnn

Advantages

nnnn

high measuring dynamics Nv

nnnn

(up to 1 : 1000)

nnnn

measuring range from 0.2 m/s

nnnn

low measuring uncertainty, even

nnnn

at lowest flow velocities

nnnn

direct air/gas mass flow-

nnnn

proportional measuring.

nnnn

Additional measuring of

nnnn

pressure and temperature not

nnnn

necessary

nnnn

sensor has no moving parts

nnnn

stainless steel sensor housing

nnnn

greater working temperature

nnnn

and pressure ranges

nnnn

low installation costs

nnnn

low pressure drop due to small

nnnn

dimensions

nnnn

long life

nnnn

sterilisable (sensor material-

nnnn

resistance allowing)

nnnn

optional, double-spaced LCD:

nnnn

volume flow / counter

nnnn

parameterization and optimal

nnnn

integration with PC software

nnnn

Range and examples of

nnnn

application

nnnn

measuring

nnnn

- air velocity

nnnn

- compressed air and gas

nnnn

consumption, leakage

nnnn

- laminar flows in clean rooms

nnnn

or machines

nnnn

- in outgoing air, burner supply

nnnn

air and draughts

nnnn

- in climatic applications

nnnn

- in air in rough vacuum range

nnnn

with pressures greater than

nnnn

200 hPa abs.

nnnn

Particles, condensation,

nnnn

humidity in the gas

nnnn

charges in the gas caused by

nnnn

particles such as dust and fibres

nnnn

do not affect the measurement,

nnnn

as long as abrasion and agglo-

nnnn

meration do not occur on the

nnnn

sensor

nnnn

deviations in values as a result

nnnn

of variable air humidity in nor-

nnnn

mal atmospheric conditions are

nnnn

covered by the measuring

nnnn

uncertainty specifications
