General instructions

Check the package for external damage and contact your distribution partner if the instruments have visible defects. Check that the delivery is complete and corresponds to the delivery note.

This product is a precision measuring instrument. We would like to point out that you should take due care when choosing the installation site and following these suggestions and instructions. Before installing, check that the specification on the type label matches your application.

Please read through these operating instructions carefully before commissioning. Incorrect operation, errors in comprehension and the consequences of these can lead to breakage of the instrument or risk of personal injury.

Commissioning and maintenance must be carried out by appropriately qualified personnel. Proper use of the products is a necessary precondition for their smooth operation.

Safety information

 The instruments must not be used outside the specified operating limits

(See also section Technical Data)

 Incorrect operation can lead to breakage of the instrument or risk of personal injury.  When using toxic media it is strongly advised not to use glass cylinder measuring instruments:

cylinder breakage and leaks can cause risk of personal injury

 Shocks, e.g. caused by magnetic valves, should be avoided.  The measuring instruments must be used solely for the medium specified in the delivery note.

Media which differ from this may lead to impaired durability and therefore cause leakage

General information

Operating principle of the variable area flowmeter

The measuring instrument works according to the float measuring principle

The measuring unit consists of a tapered graduated precision glass measuring cylinder in which a ball float can move freely up and down. The medium flows through the vertically-aligned measuring cylinder from the bottom upwards.

The float positions itself so that the buoyancy force A acting on it, the form resistance W and its

weight G are in balance::

G = A + W

The flow rate can be read as the height of the float on a scale on the tapered measuring cylinder. The value is read off at the middle of the float (largest diameter).

Variable area flow meter type marking

The instrument type label is attached to the inside of the left side panel in the V-100 and on the back of the mounting plate in the Q-Flow:

Example:

Key:

SN: Serial number – Position – number of instruments per position BE: Customer order number 07/08: Date of manufacture, month/year Type: Specification in accordance with type code (standard instruments only) 1

Medium, measuring range, measurement unit, pressure, temperature and additional information.

1

Custom designed instruments are given a seven digit product code instead of a type code

(e.g. 137-1215).

High-precision control valve type marking

For the M-Flow the type label is attached to the valve cartridge housing. An arrow on the body of the valve indicates the flow direction.

Example:

Key:

NS 2.5: Specification of valve size NS 1.0 to NS 6.5 L: Closing direction for valve (L = left / R = right) V: Sealing material (V = FKM / E = EPDM / P = FFKM

Custom designed instruments can have additional details such as leakage rate.

Installation and commissioning

General instructions

Measuring instrument design

In addition to the type code (see appendix) we require you to supply the following information for optimal design of the instrument:

 Medium  Maximum flow rate  For design without valve: Pressure in measuring cylinder  For design with valve: Pressure before and after the control valve  Temperature

When should the control valve be mounted at the outlet?

 In vacuum processes the gas expands considerably. This leads to significant measurement

errors. The control valve should therefore always be placed at the outlet for vacuum applications.

 Liquids often contain gas bubbles. These settle on the float. This results in a higher flow rate

being displayed. By installing the control valve at the outlet the gas bubbles become smaller and are better able to flow past the float.

 In the case of fluctuating back pressure (e.g. when gassing a liquid container if the level varies

markedly).

 In the case of pulsating media or smaller water hammer the valve at the outlet has a cushioning

effect.

When should the control valve be mounted at the inlet?

 In the case of constant after-pressure  If the control valve also has to serve as a locking valve. (e.g. if a measuring cylinder has to be

exchanged when installed).

Direct reading scale or mm-scale?

The direct reading scale (also known as the product scale) is determined for only one operating condition. The mm-scale is not dependent on the medium, pressure and temperature. Different tables with various operating conditions can be used. The actual measurement value is not visible directly on the instrument but is read using a conversion table.

What is the purpose of standard liters and norm liters?

In contrast to liquids, gases can be compressed, so it is important to know the density of the gas used. This in turn is dependent on pressure and temperature, i.e. if two quantities of gas are to be compared with one another, then the current pressure in the pipe and the current temperature of the medium must be known.

We supply general tables relating to norm liters 0°C 1013 mbar a

The two quantities are defined as follows:

Unit Pressure Temperature

Standard liter 1013.25 mbar a 20°Celsius Norm liter 1013.25 mbar a 0° Celsius

The US standard liter corresponds to the German norm liter (0°C 1013.25 mbar a). However, there are other reference temperatures. Gas suppliers use a reference temperature of 15 °C.

Conversion of standard liter (Stdl) into norm liter (ln) and vice versa:

Stdl = (ln/273.15)*293.15 ln = (Stdl/293.15)*273.15

Limit indicator

The V-100 variable area flowmeters can be equipped with a maximum of two limit indicators.

The instruments with limit indicators have the following standard design:

Minimum Switch Maximum Switch

Initiator position

Switching status

Note: In case of power failure, the contact closes irrespective of the position of the float.

For initialization, the float must first pass the initiator so that it is recognized by the initiator and the float position is defined.

When used correctly, variable area flow meters from Vögtlin Instruments AG do not require any maintenance.

Soiling

The following symptoms indicate soiling:

 The set value can no longer be reached – the control valve is probably soiled  The measuring value rises although the actual flow rate has not been changed – measuring

cylinder is soiled

 Colour change / deposits in the measuring cylinder

Cleaning

Depending on the type of soiling, the measuring instrument can be rinsed with isopropyl alcohol (IPA). The measuring cylinder can be mechanically cleaned with a brush at the most.

If soiled, we recommend that you return the measuring instrument to your distribution partner.

Return

When returning, please use the original packaging if possible or suitable alternative packaging. We do not accept responsibility for damage in transit. Please inform us of the reason for return: this enables us to process your request quickly.

Note

If the instrument has been in contact with corrosive or toxic media it is imperative to clean it properly before return. Please always complete the contamination declaration form. This is provided in the appendix to this manual.

Instruments which we receive without a contamination declaration form will unfortunately have to be returned to the sender.
