Products that do not operate properly during this period may be repaired or replaced at no

charge. Repairs are normally warranted for one year or the balance of the original

warranty, whichever is the longer.

See also paragraph A-V and B-II of the Terms and Conditions of sales of the

M+W Instruments GmbH.

The warranty includes all initial and latent defects, random failures, and indeterminable

internal causes. It excludes failures and damage caused by the customer, such as

contamination, improper electrical hook-up, physical shock etc.

Re-conditioning of products primarily returned for warranty service that is partly or wholly

judged non-warranty may be charged for.

M+W Instruments GmbH prepays outgoing freight charges when any party of the service

is performed under warranty, unless otherwise agreed upon beforehand. However, if the

product has been returned collect to M+W Instruments GmbH, these costs are added to

the repair invoice. Import and/or export charges, foreign shipping methods/carriers are

paid for by the customer.

1 ANALOG INSTRUMENTS

All necessary settings for this instrument are already performed at M+W Instruments

GmbH. Following the next steps carefully is the quickest way to get the instruments

operational in your own system.

1.1 General

The analog instruments of M+W Instruments GmbH are measurement devices for thermal

mass flow and control of gasses and gas mixes. The flow signal is measured directly in

the gas flow from 0.5...10 ln*/min up to 300...6,000 ln*/min and controlled when a control

valve is applied.

[* n = normal conditions: At normal conditions the volume is regarded at a temperature

of 0°C and a pressure of 1013.25 mbar (a)]

As an option ex work the device can be equipped with an integrated 3½ digit LCD flow

rate indication or with an integrated 8 digit counter.

Output signal / setpoint: 0…5V dc OR 4…20 mA

Power Supply: +15 Vdc OR +24 Vdc (please check on instrument label)

ATTENTION!

The input and output signals are NOT galvanically isolated!

Scope of Delivery

Immediately upon receipt of the incoming goods the package needs to be checked for any

possible damages and the goods have to comply with the scope of delivery listed on the

packing note. In case of any damages the supplier and the freight forwarder have to be

contacted without delay.

When the instrument needs to be returned please include a description of the damage in

a closed envelope.

ATTENTION!

All instruments for return must have a fully filled-in “Declaration of Decontamination“.

This declaration has to be attached to the shipping documents, allowing free access on

the outside of the package.

The declaration of decontamination is available on our accompanying CD with each

instrument shipment or it can be downloaded from our website www.bronkhorst.com.

Please mention the instrument’s model code and the serial number on your order, as well

as your VAT number when needed.

1.2 Installation

To avoid personal injury and/or damage to the equipment only trained and qualified

personnel shall perform the installation of the instruments:

−Read the instrument’s name plate before installation and check the electrical

connection, flow range, media to be measured, inlet and outlet pressure as well as

input and output signals.

−The instruments contain electronic components which are sensitive to electronic

discharges (ESD). Contact with electronically charged persons or objects could

possibly endanger these components or even result in their failure.

−While installing the instrument take care of the arrow marking on the instrument’s flow

body, determining the flow direction.

−Ensure that all piping is absolutely clean and without any damage. It is recommended

to install an inlet filter in front of the instrument.

−Avoid piping with small diameter at high flow rates. When possible no abrupt angles or

other disturbances shall be mounted directly in front of the instrument.

−All devices have Withworth pipe threads – type RP – according to ISO228-1

(cylindrical G-threads in inches according to BSPP). The mounting of NPT-fittings will

destroy the inlet threads in the instrument’s body.

−Using an inlet pipe with sufficient piping diameter is recommended. The length of the

inlet pipe should be at least 10 times the piping diameter.

−Before the first start-up check that the system has absolutely no leakage. If toxic,

explosive and/or corrosive gases are to be used, ensure to purge the system long

enough with a dry, inert gas. This is also required to remove these kinds of gases from

the system.

−The instruments’ preferred mounting position is horizontally. Especially when installing

bigger mass flow controllers (D-6273 and bigger) in different ways you should get in

contact with your distributor or M+W Instruments GmbH beforehand.

All instruments described in this manual carry the CE-mark. Therefore they have to

comply with the EMC requirements valid for these instruments. However compliance with

the EMC requirements is not possible without the use of proper cables and

connector/gland assemblies.

In case the instrument is connected to other devices (e.g. power supply) ensure that the

operating voltage complies with the supply voltage given on the name plate and that the

function of the shielding is not affected. M+W Instruments GmbH recommends using

standard cables following the CE-requirements and could supply them when needed.

1.3 Operation and Maintenance

When the power is switched on a warm-up period of at least 30 sec is required allowing

the instrument’s thermal stabilisation. Afterwards the instrument will work with an

accuracy of approximately 4% FS. It takes around 30 minutes until the optimal stability is

reached and the instrument will work with an accuracy of < 3% FS. This is supposed to be

performed with or without gas flow. To avoid creating gradients it is recommended that

gas and ambient temperature are kept at the same level (max ΔT approx. ± 2…3 °C).

Otherwise the accuracy of this thermal measurement could be affected in an

unpredictable manner.

Be sure that the specified pressures have been applied. Pressure surges, as may occur

during the system pressurisation, must be avoided. The control valve cannot be used as a

shut-off valve. When starting up, always bring the instrument gradually up to the level of

operating conditions.

There are no regular maintenance checks required for the instrument’s operation. It has to

be ensured that a possible mounted inline filter is checked and cleaned on a regular

basis. We recommend having the calibration checked every 24 months by the supplier or

an authorized service partner.
