Non-contact ultrasonic gas flow measurement

and volume counting, suitable for

all gases available meter sizes DN 50-600

and 2”-24”.

Wide range of application

The large range of products that can be

measured accurately and easily make this a

truly universal device. Just a few examples:

Natural gas

• Air

• Methane

• Nitrogen

• Determination of the molecular weight of

gases

• Measurement in hazardous locations, Zones 1 and 2

Calibrated on EN 17025 accredited calibration rigs,

calibration accuracy better than 99.97% of the

measured value.

2 Size, flow velocity, flowrate

Selection of meter size / nominal pipe size

Flow velocitys in m/s or ft/s and the flowrate in m3/h or

US Gal / min can be determinded for each meter size

(DN) using the Tables below.

Precise determination of flow velocities

For range setting, use the flow table below to determine

the precise flow velocity for each nominal pipe size.

Example: v in m/s Example: v in ft/s

Nominal pipe size DN 150

Required measuring range 1000 m3/h

Nominal pipe size 6”

Required measuring range 5000 US Gal / min

For a flow velocity of 1 m/s at DN 150,

the table gives a flowrate of 63.617 m3/h.

For 1000 m3/hr, the flow velocity v is thus

For a flow velocity of 3.3 ft/s at 6’’,

the table gives a flowrate of 280.11 gal/min.

For 5000 Gal / min, the flow velocity v is thus

1000 m3/h x 1 m/s

v = -------------------------- = 15.72 m/s

63.617 m3/h

5000 US / min x 3.3 ft/s

3 Measuring principle

All KROHNE ultrasonic flowmeters operate using the

transit-time differential method.

Transit-time differential measurement is based on a

simple physical fact.

Imagine two canoes crossing a river on the same

diagonal line, one with the flow and the other against the

flow. The canoe moving with the flow needs much less

time to reach the opposite bank.

Ultrasonic waves behave exactly the same way. A sound

wave travelling in the direction of flow of the product is

propagated at a faster rate than one travelling against the

flow (vAB > vBA).

Transit times tAB and tBA are measured continuously. The

difference (tBA - tAB) in time travelled by the two ultrasonic

waves is directly proportional to the mean flow velocity

(vm) of the product.

The volumetric flowrate per unit time is the product of the

mean flow velocity (vm) multiplied by the pipe cross-

section.

A liquid product is identified by direct measurement of the

transit time of ultrasonic waves. Assuming the same path

length (L), the transit time in water is shorter than in crude

oil, for example.
