Krohne VA40/ VA45 Variable area flowmeter

1.   VA40 VA45 Variable-area flowmeter

The VA40 flowmeter is suitable for measuring the flow rate of liquids or gases.

The VA45 flowmeter is suitable for measuring gases at low operating pressures

Highlights

• Consistently used overall length concept

• Low loss of pressure for gas applications

• Low maintenance

• Optional limit switches

• Simple installation and start-up

• Simple float guidance

• Shatter protection

3.2 Measuring ranges

Measuring ranges VA40

The oper. press. should be at least twice the pressure loss for liquids, and at least 5

times the pressure loss for gases! The specified pressure drops are valid for water and air at

maximum flow rate. Other flow ranges on request.Conversion of other media or operating data

(pressure, temperature, density, viscosity) isperformed using the calculation method in

accordance with VDI /VDE Directive 3513.

Measuring ranges VA45

The operating pressure should be at least 5 times the pressure loss for gases! The specified

pressure drops are valid for water and air at maximum flow rate. Other flowranges on request.

Conversion of other media or operating data (pressure, temperature, density, viscosity) is

performed using the calculation method in accordance with VDI /VDE Directive 3513.

3.3 Installation condtitions

When installing the device in the piping, the following pointsmust be observed:

• The variable area flowmeter must be installed vertically (measuring principle). Flow direction

from bottom to top. For installation recommendations please refer also to VDI/VDE 3513

Sheet 3.

• Before connecting, blow or flush out the pipes leading to the device.

• Pipes for gas flow need to be dried before the device is installed.

• Use connectors suitable for the particular device version.

• Align the pipes centrically with the connection bores on the measuring device so they are free

of stresses.

• If necessary, support the pipeline to reduce vibrations being transmitted to the measuring

device.

• Do not lay signal cables directly next to cables for the power supply.
