nnnn

Vortex Flow Sensors VA Di

nnnn

also suitable for applications in condensation and particle laden gases

nnnn

Measurable variable

nnnn

actual flow rate

nnnn

standard velocity

nnnn

standard flow rate (in

nnnn

combination with pressure

nnnn

and temperature sensors)

nnnn

Design

nnnn

measuring tube

nnnn

Functional principle

nnnn

vortex meter for measuring

nnnn

flow rate and volume

nnnn

ultrasonic measurement of

nnnn

the vortex shedding

nnnn

Medium

nnnn

primarily single-phase gas

nnnn

mixtures with air, nitrogen,

nnnn

oxygen, methane, natural

nnnn

gas, flare gas, ammonia,

nnnn

argon, carbon monoxide,

nnnn

steam ... as dominant

nnnn

component, combustion

nnnn

exhaust gas, bio gas,

nnnn

sewage gas.

nnnn

Other gases on request.

nnnn

Particles, condensation,

nnnn

humidity in the gas

nnnn

charges in the gas caused

nnnn

by particles such as dust

nnnn

and fibres do not affect the

nnnn

measurement, as long as

nnnn

abrasion and agglomeration

nnnn

do not occur on the sensor

nnnn

relative gas humidity of less

nnnn

than 100 % does not affect

nnnn

the measurement

nnnn

uncertainty

nnnn

Advantages

nnnn

low starting value

nnnn

high measuring dynamics

nnnn

(up to 1 : 100)

nnnn

no moving parts

nnnn

maximum fatigue strength

nnnn

corrosion resistant

nnnn

operates to a large extent

nnnn

irrespective of gas

nnnn

composition

nnnn

low pressure drop

nnnn

easy adjustment to process

nnnn

parameter

nnnn

Range and examples of

nnnn

application

nnnn

flow measurement, for

nnnn

example, of air, exhaust

nnnn

gas, process gas, bio and

nnnn

sewage gas, engine intake

nnnn

air, exhaust emissions,

nnnn

gases laden with particles,

nnnn

dust and fibres, superheated

nnnn

steam

nnnn

depending on the density,

nnnn

condensation on the sensor

nnnn

may affect measurements.

nnnn

The vortex signal processing

nnnn

module VSM can help reduce

nnnn

measurement uncertainty if

nnnn

condensation is moderate;

nnnn

requirement: external

nnnn

evalutation unit instead of

nnnn

integrated transducer UVA
