Applications of the fitech -Flowmeter
The fitech -Flowmeter is used for measuring the flow of high-viscous, pasty products.
Depending on the product to be measured, different size nozzles may be used, however, the
standard-size nozzle has a 4 mm hole, H7.
Introduction to the Operating Manual
This Operating Manual includes information on the safety, use and maintenance re-
quirements of the fitech -Flowmeter.
It is to be thoroughly studied and understood by the operator of the equipment as well as all
staff using the fitech -Flowmeter. Specific instructions and training must be provided in order
to ensure a safe operation of the equipment.
The Flowmeter has been built according to the latest technical standards in all respects, also
its safety. The use of the measuring equipment, although rather simple, may cause
grievous physical injury to personnel working with it, should operating instructions not be
followed. Fitech excludes any responsibility for damages or injuries whatsoever that may
result from non-compliance with or non-comprehension of these instructions. Furthermore,
all requirements by the operator of the plant himself and any locally applicable statutory
laws, regulations, etc. that might be applicable must be adhered to.
Please note that this Operating Manual does not provide instructions on repairs that go
beyond maintenance of the plant.
Safety, operation and maintenance
CAUTION: Regulations of use of laboratory equipment etc., labour laws in force
at the place where the equipment is used must be strictly adhered to!
CAUTION: The Flowmeter is operated with compressed air. All necessary caution
when using it is to be employed!
Protect your body against harmful incidents, your eyes with the appropriate
safety glasses or goggles, the hands with the appropriate safety gloves, etc.
CAUTION: All required safety measures must be in place during the entire use of
the equipment!
CAUTION: Ensure no pre-set limits are exceeded!

Place of operation
The Flowmeter is to be carefully unpacked and checked. Should you notice any transport
damage please inform us immediately. We will replace damaged parts as quickly as possible.
CAUTION: The use of a damaged Flowmeter may be the cause of grievous
physical injuries to personnel operating it. fitech declines any responsibility for
injuries or damages connected with a damaged Flowmeter!
To operate it, the Flowmeter is to be placed on a strong, level base (such as a solid table).
For its operation a connection to compressed air only is required. Please make sure that the
air suppied is dry and filtered, air pressure supplied must not exceed 5.5 bar.
Depending on where the Flowmeter is placed and space is available, the products measured,
etc., additional safety measures may need to be taken or installed. Prior to its first use the
operator checks the place of operation and the surrounding area thoroughly and implements
additional safety measures if necessary.
Operation
Prior to its first operation, the following points must be checked:
-All screwed connections are fastened tightly, either manually where indicated, or by
using the correct tools.
-All air pressure connections and fastenings are tight.
-Make sure the safety relief valve is operating properly and release follows when pressure
exceeds 6 bar. Thereafter, its function must be checked periodically, also according to
local as well as owner's regulations.
-The threads of the manually screwed parts like nozzle (Pos.5), nozzle carrier (Pos. 4) and
measuring cylinder (Pos. 3) must be lubricated with an appropriate lubricant (such as
fat). In no case must it contain Silicon and the properties of the greasing agent must be
compatible with the product to be measured. The same applies each time the equipment
is cleaned after measuring a product.
Preparations for measuring
CAUTION: During measuring no fastenings may ever be loosened or
disconnected. The Flowmeter must be completely pressureless by switching the
hand valve (Pos. 8) to OFF and checking that the pressure gage shows zero
pressure!
Proceed as follows:

fitech ag Switzerland Operating Manual page 5
fitech-Flowmeter
1. Choose size of nozzle in accordance with the product to be measured and screw chosen
nozzle (Pos. 5) manually and solidly into the nozzle carrier (Pos. 4).
2. Remove measuring cylinder (Pos. 3) from pressure cylinder (Pos. 2) by unscrewing
manually. Turning the measuring cylinder upside down, the pressure plate (Pos. 6) slides
out of the cylinder. Ensure it is not dropped on to a hard surface!
3. Make sure that nozzle (Pos. 5) has been screwed tightly into the nozzle carrier (Pos. 4)
and latter one has been tightly screwed into the measuring cylinder (Pos. 3), tightening
is to be done manually only.
4. Now fill measuring cylinder (Pos. 3) from the top with the product you intend to measure
by pressing out a cartridge or filling from an other vessel. Ensure that no air bubbles are
locked into the product to be measured. Leave enough room to place the pressure plate
(Pos. 6) above the material.
5. Screw measuring cylinder (Pos. 3) manually tightly onto the pressure cylinder (Pos. 2).
Make sure O-ring (Pos. 16) is properly positioned on the pressure cylinder so as to
exclude an air leak.
CAUTION: The parts mentioned (nozzle, nozzle carrier, measure and pressure
cylinders) are precision parts with very fine threads. When screwing together
take care not to set threads canted against each other. All parts, including the
pressure plate should be handled with care at all times.
Measurement
6. First set the Flowmeter to the desired pressure. This is attained by positioning the hand
lever (Pos. 8) to 'pressure' and by subsequently adjusting pressure shown on the
pressure gage (Pos. 7) to the desired pressure by adjusting the pressure regulator
(Pos. 9) accordingly.
7. Position your laboratory scales, together with a vessel into which the measured product
may flow, under the nozzle, tare the scales.
8. The measuring of the flow is done by starting simultaneously a stop-watch and switching
the pressure on with the hand valve (Pos. 8) to ON. After reaching the desired measuring
period switch off both simultaneously again, the stop-watch and the pressure valve
(Pos. 8).
Please note that since the amount pressed through the nozzle is generally small, it offers you
the possibility to get two to three measurements for comparison.
CAUTION: Should the product to be measured react with humidity in the air used
for flow measurements, it is up to you to decide on whether to use dried air or
rather nitrogen!

Cleaning
With the conclusion of the flow measurements, the Flowmeter is to be thoroughly cleaned.
Follow these steps:
-Ensure that the Flowmeter is not under pressure by making certain that hand valve (Pos.
8) is in OFF-position. Make sure reading on pressure gage is nill, then remove
compressed air connection.
-Unscrew all manually screwed parts (nozzle, nozzle carrier and measuring cylinder),
remove pressure plate.
-Use only cleaning agents that are compatible with the product measured and which will
not harm any of the metal parts, especially the pressure plate.
-Clean the threads of the parts, including the pressure cylinder, thoroughly. It is important
however, that the threads are greased again prior to remounting the parts. Use only
grease which does not contain any parts of Silicon and which will not react with products
to be measured. Remount cleaned and greased parts as indicated under 'Preparation for
measurements'.
Your Flowmeter is now ready for further measurements, store in a well protected and clean
spot.
